At SafetyWing, we’re building a global social safety net for remote workers — simple health, insurance, and retirement products designed to replace national welfare systems. Our mission is to remove geographical borders as a barrier to equal opportunity and freedom for everyone.

Our ambassador program has been one of the most powerful growth channels for Nomad Insurance Essential since 2019, driving more than 35% of sales. This Partnerships Manager role brings that proven model to a new b2c product: Nomad Insurance Complete. You'll be among the first dedicated to building its ambassador program from the ground up. Experiment, source, pitch, onboard and grow.

SafetyWing is a team of ~150, fully remote since day 1, globally distributed, and async-first by nature.

We look forward to hearing from you! Apply via the link here: https://safetywing.pinpointhq.com/postings/df3a7344-aa17-469...

Banking Circle provides account and payment infrastructure to other regulated financial firms. You have probably never heard of us but we have probably moved money on your behalf at some point this month.

As part of this we need to screen payments for sanctions compliance and anti money laundering and fraud concerns. The team hiring builds the ML models that decide if the payment needs to go for manual review.

We’re a diverse mix of people (50% have PhDs) and we work a wide ranging set of problems.

Specifically we are looking for candidates to strengthen our GIS (geolocation) / graph (network) and NLP (genAI) capabilities.

A good candidate will have experience in two of the three areas, a track record of delivering business relevant results and some research experience.

I'm a solo founder. I built the entire product myself, got 11 fire departments paying with zero churn, and now I need someone to own engineering so I can't be the only one who does. West Point, Ranger Regiment, Yale Law, still the only developer.

What we do: Hotwash is an after-action review platform for fire departments. After a serious call, crews record what happened, we transcribe and structure it, and the hard-won lessons become searchable institutional memory instead of retiring when the veterans who earned them do. Fire is the wedge; the long game is operational learning for any high-reliability organization.

Traction: $40K ARR, 11 paying fire departments, zero churn. Raising a $1M pre-seed.

The role: Employee #1 on engineering. You own the codebase, architecture, and UX end to end, and you lead the rebuild off the current stack. You work directly with me on what gets built and why, including sitting with fire chiefs to figure out what they actually need. For the right person this becomes the CTO seat.

Who I'm looking for: A full-stack engineer who ships simple, usable products and has a real eye for design. Our users are fire crews, not power users, so the bar is "obvious to someone who's never seen it." If you care about how software feels, not just whether it works, this is your seat.

Stack: Today it's FlutterFlow + Firebase, Node, with Groq/AssemblyAI for transcription and Gemini for summarization. The rebuild target is React Native (Expo), Cloudflare Workers, D1, R2. You'd own that migration, so this is real greenfield ownership, not maintenance.

Comp: Founding equity, scaled to scope.

We're pre-raise, so cash is lean right now and grows when we close.

Email hiring@hotwash.com with a resume, link to something you've built, and one line on why this interests you.

I've tried FlutterFlow. I might even be using it now for prototyping. But with coding agents in all the IDEs, why bother?

I have hands-on experience in information security, penetration testing, and SOC operations. I’ve worked with Splunk SIEM monitoring, threat hunting, vulnerability assessment, digital forensics, and incident response fundamentals. I’m ranked in the top 1% on TryHackMe with 13 certifications and placed 2nd in IBM ICE DAY 2025 CTF.

Impact: – Built real-time threat detection systems. – Built DDoS mitigation solutions. – Developed secure cloud applications with authentication, encryption, and access control. – IBM academic internship: Tejas Raksha, a zero-day web scanner for OWASP Top 10 vulnerabilities. – Freelance cloud security work: AES-256-GCM and Argon2id file encryption, MFA/SSO/RBAC, WebAuthn/TOTP, and secure healthcare workflows.

We are looking for an Enterprise Security Engineer to help build and operate Compa’s security-first enterprise environment.

This is a senior individual contributor role reporting directly to the Head of Security & IT. You'll own the systems that define how employees access, use, and interact with technology at Compa — identity, access, endpoints, and enterprise SaaS — and treat them as core security infrastructure, not traditional IT.

This role sits on the Security team and partners closely with the rest of the business to help Compa move fast, securely, all while delivering a world-class employee experience.

We're open to candidates earlier in their career who demonstrate strong systems thinking, sound judgment, and the ability to design for scale. We care more about what you can do than how many years you have been doing it.

Upwave builds brand measurement software for large advertisers, agencies, and media partners. We process high-volume ad exposure + survey/event data and turn it into brand lift, reach validation, optimization recommendations, and AI-assisted analysis for enterprise marketers.

We're looking for a senior full-stack/backend-leaning engineer who can be productive quickly in our JVM/Spring Boot stack. Recent production experience with Java, Kotlin, or similar is important for this role; we need someone who can help us ship and operate backend services without a long stack ramp-up. Strong candidates also bring Python, SQL/data modeling, AWS/Kubernetes/observability, and high-volume event or analytics pipeline experience.

The work includes building APIs and data pipelines, productionizing analytics/statistical workflows with Product and Data Science, improving reliability/performance, and building AI-powered customer experiences. Stack includes Kotlin/Java, Python analytics services, React, MySQL, DynamoDB, AWS, Kubernetes, Terraform and LLM orchestration.

We're profitable/growth-stage, remote-first in the US, and engineering-led: high velocity through focus and leverage, not crunch. Interview process includes an in-person meeting.

Apply: https://www.upwave.com/job/8547924002/ Or email me directly: jason.kelly@upwave.com

Wrenly is a bootstrapped, profitable HR / people-analytics SaaS. We collect performance and engagement data where teams already work (Slack, MS Teams), and our AI turns it into plans managers actually act on. We go up against Lattice and Culture Amp with a fraction of their headcount.

We're hiring our first CSM. You'll own onboarding, support, QBRs, renewals and expansion — and you'll do it with AI as the primary tool, not a side feature. Claude is how you'll triage tickets, investigate our codebase, write docs, and automate the repetitive parts of the job, so the knowledge base answers the next customer before they ask.

Hard requirements: - Based in Brazil, comfortable with US Eastern time-zone overlap - Fluent written and spoken English - 100+ hours of real hands-on experience building AI agents/automations. This is a genuine bar — if you haven't, this isn't the role. - 1-4 years in B2B SaaS customer success / account management is ideal but not required; we care more about how you work than how long you've done it.

Comp & perks: USD $16k-$26k base + commission on expansion, fully remote, 40h/week, 20 days off/year total, all tools and AI plans covered, real input on product from day one.

Company: We’re building a geologic modelling software, based on reasoning, to help mining and mineral exploration companies work faster. Our goal is to create a way to enable open-ended, interpretive geologic problem solving to be done programmatically, changing the way to explore for hard rock and critical minerals. Currently in active fundraising.

Role: You are the founding engineer on the team, joining co-founder (Neil, CEO) and myself (Jeff, CTO) as first employee. You’ll have a deep influence over systems and architecture. You will have ownership through the entire stack from the database, through geostatistical backend services, through 3D rendering on the client side.

Work rooted in agentic systems, so an understanding of the internals of things like Claude Code, and a broader understanding of orchestrating agents to complete complex discrete tasks is important.

You:

- Fluent in Typescript, Python, and framework/tooling agnostic (Currently using things like NextJS, Supabase, Cesium)

- Eager to learn about mining domain knowledge around the software.

- Ownership of the codebase, and the systems that support the software (project management, CI/CD, monitoring, etc.)

- Strong engineering fundamentals around architecture, systems and security.

I'm building an AI-native operations tool for private mortgage lenders. MVP targets two workflows that eat servicing staff time: NSF collections follow-up and renewal management. I run a Canadian private lender as my day job, so the product is built against a real shop with real data and real users. Self-funded. No VCs, no board.

The data model is locked (20 tables, multi-tenant by lender_id, idempotent CSV imports, append-only event log). Wireframes in progress. Hiring one engineer for the full ~6-month build via a paid bake-off: $5k flat for ~1 week of work, 2-3 candidates in parallel, winner takes the engagement. Losing candidates get paid in full and keep their work.

Trial scope: CSV loan tape import with idempotent upsert + audit, one case detail screen, one LLM call classifying a borrower email reply with structured output, activity log driven by case events. Stack is contractor's choice — Postgres required, Next.js + TS or Python + React expected.

Looking for senior generalists with real production LLM experience (structured outputs, evals, failure modes — not side-project tier) and strong relational data modeling judgment. Opinions you'll defend in writing.

Email: info@readifinancial.com

with: one paragraph on why this interests you, 1-2 links to shipped work involving a real schema + LLM in production, your rate and availability, and one question about the project. No cover letters.

Search terms: postgres, multi-tenant, LLM, OpenAI, Anthropic, Next.js,

We're hiring an Analytics Engineer to help power our future. This is a really greenfield project where we need to define the data models that fuel all reporting, analytics, and ML/AI going forward. We do 'freight audit' - we save our clients money by making sure all their logistics spend is correct and as agreed.

At Trax, our data infrastructure is in the middle of a real transformation. We're building the data foundation that will power our next wave of AI features, and we need someone who can own that work end-to-end. This isn't a "run queries and make charts" role.

You'll be:

- Designing and maintaining data marts in dbt + Snowflake

- Building customer-facing dashboards that integrate into our platform

- Bridging the gap between engineering, business ops, and client teams

- Running ad-hoc analyses that drive real decisions

- Shaping how our data platform evolves alongside our AI/ML capabilities

What matters most to us:

- Deep data modeling knowledge (domain logic, not just syntax)

- Advanced SQL; dbt and Snowflake experience is a big bonus

- Strong communicator who translates between technical and non-technical worlds

- A learning mindset; genuinely non-negotiable for us

We're a small, close team. You won't disappear into a large org. You'll work directly with leadership, partner with Solutions and Sales, and have a real voice in how we build. If you thrive on ownership, are energized by complexity, and want to see the direct impact of your work, let's talk! My email and linkedIn are in my profile.

We work with robots that run biology experiments. The robots are accurate, but programming them by hand takes so long that most labs don't bother. So we wrote a compiler and visual editor a scientist can use. They describe their protocol in plain language, we parse it into a structured format, and compile that to optimized code. Our end goal is to build the infrastructure for autonomous science and a centralized cloud lab. Short demo: https://tinyurl.com/mrx63phb

The team is three software engineers, an automation engineer, the founders, and soon a designer. The codebase is one monorepo containing an OCaml compiler, Python backend services, and a TypeScript/React editor. The challenges come in the form of eliciting scientific context and tacit knowledge and in the fact that a protocol has to deterministically run correctly.

We are looking for at least 3 years of experience. OCaml isn't a requirement, just a willingness to learn it. Nice if you've done DSLs, compilers, life sciences or lab automation, an ML-family language, or LLM parsing and evals.

I'm the hiring manager for this role, which is for an IC tech lead. Please see the full job description for details, but I'm looking for someone who is comfortable leading engineering discovery and working with Product on roadmap planning within the API payroll integrations space. The most important thing in this role will be driving your own pace and taking projects from inception to completion. A successful candidate will be good at working efficiently without many hard deadlines or micromanagement. We also want someone who has strong systems design experience and good technical leadership skills. In terms of tech stack, it's mostly Python and Typescript, including nest.js

Our interview process is pretty straightforward. There's a phone screen with our recruiter, then a culture fit/qualifying interview with my boss, a technical interview with a real-world problem (no leetcode), and finally a cross-functional team interview with myself and another engineering leader at my company. We move pretty quickly and aim to keep the process respectful of everyone's time. Happy to answer any questions here! If you'd like to apply, please email recruiting [at] vestwell [dot] com with your resume.

We’re on a mission to radically transform the way we design and construct our built environment.

Backed by Lightspeed Venture Partners, Eagle acquires civil, structural, and MEP engineering firms and transforms them with applied AI. Our thesis: 85% of what engineers do is automatable, yet less than 5% has been touched by AI; the largest gap of any profession. By arming designers with frontier technology, our ambition is to build the most valuable, talent-dense engineering firm in the United States.

We're looking for founding members of technical staff. If you get excited about building from zero, get energized by direct access to users, and want to work in a problem domain that's barely been touched by AI, we'd love to talk.

Carma (https://www.joincarma.com/) is an AI-native operating system for enterprise fleet operations. Fortune 500 construction, electrical, and disaster restoration fleets run thousands of commercial vehicles on our platform in production today. When a truck breaks down, gets recalled, or sits idle, our software detects it, builds the workflow, and drives it to resolution automatically. Ship a feature in the morning; a fleet manager in the field is using it within the hour.

Why it's technically interesting: real-world software with messy, adversarial data — telematics streams, OEM recall feeds, vendor invoices, DOT compliance — fused into workflows that AI agents execute. The incumbents in this multi-billion-dollar market ship on decade-old stacks. We raised a $5.5M seed from Y Combinator, Soma Capital, and the founders of Superhuman, and we're driving toward a Series A.

Stack: TypeScript end-to-end — React, NestJS, PostgreSQL + Prisma, AWS.

Two founding roles, both heavy on ownership:

1) Founding Head of Engineering: $300K–$450K + 3–5% equity. Hands-on technical leader: the majority of your time writing production code, plus owning architecture, standards, and technical direction. Explicitly not a people-management track.

2) Founding Full-Stack Engineer: $175K–$275K + 2–3% equity. Own product surfaces end-to-end: ambiguous problem statement → scoped design → shipped to enterprise users.

Onsite in SF six days a week, early-stage pace, high ownership and high expectations. Our process is fast, strong candidates go from first conversation to offer in days, not months.

Email suleyman@joincarma.com with 2–3 lines on the hardest system you've shipped end-to-end. We reply to every thoughtful email within 24 hours.

By fraudulent I mean: fake resumes, names stolen from real developers who work at well-known companies but either don't have a linkedin/portfolio or do have a linkedin/portfolio without a profile picture. So easily impersonated by a scammer.

It is a real shame, but this thread is now being scraped by plenty of other sites and bad actors.

Inbound hiring for remote teams is basically cooked at this point, signal is completely hidden in the noise. Curious if anyone else has had this experience or if it's just me?

But no, it's just a performance. The director can claim they're behind on projects because they don't have enough staff, but everyone they interview isn't qualified (because the interviews are impossible and nearly everyone trips up)

I started seeing this pattern recently.

The companies that are serious move fast. A chat with the hiring manager. A couple technical interviews, maybe on-site for 2 hours. A chat with someone higher up. Done, offer made.

On an unrelated note, your localias project is really cool! Going to give it a spin tonight.

As a job seeker, I see the chaos from my side of the table, I feel like its well known and discussed.

The other side of the table however, the recruiters and hiring managers, I want to understand this more. I feel like I could assume the struggles your having, but I would love to see more discussion around this.

> Commenters: please don't reply to job posts to complain about something. It's off topic here.

LinkedIn is doing nothing to stop the fraud at this point. There's almost no way to tell if you're talking to a real person unless you meet with them personally at their office.

YNAB started in 2004 and we haven’t taken any outside funding—we’re established, profitable, and in this for the long haul.

We currently have a team of 8 iOS developers and an Engineering org of about 45 total. You'd be embedded in a product team alongside a PM, product designer, QA analyst, support specialist, and a few other fullstack engineers.

If you're interested, read the full JD here and apply before June 7th at 11:59pm PT (and don't miss the 3 questions to include in your cover letter!): https://ynab.pinpointhq.com/postings/04715f30-5fb5-4ee7-9d27...

We are a seed stage startup building Tabular Foundation Models (TFM). This is an emerging space with huge potential.

LLM's like Claude take text as input and produce text. Model's like nano banana take text as input and produce images. Tabular Foundation Models take rows/columns as input, and produce predictions.

The world is sitting on huge amounts of structured data that isn't being used to its potential. Making predictions is hard. Today, most folks are building, training, maintaining their own models. A bit like you'd need to have done back in 2019 with LLM's.

We want to change that. We're looking for an early career Field Engineer to help build out demos, docs, resources, integrations as well as driving product adoption directly with customers. Someone who is passionate about building, has shipped real software (or predictions), has experience with Python and data science fundamentals.

If you're looking for something a bit different than just "hands on keyboard" engineering, and enjoy business as much as tech, this could be for you.

Feel free to reach out at aaron.stillwell@neuralk-ai.com

Small stealth team in the property management space, building AI agents that run real operations, where agents and humans work as one team rather than as user and tool. Funded, profitable, fully remote, competitive comp.

We want a senior backend engineer to own a client facing use case end to end: build the backend tools and workflows our agents call, handle the jurisdiction and client specific extensions, and talk to the client directly. Pull requirements, explain the tradeoffs, own the relationship. Take messy real world problems, turn them into something agents can actually use, then keep it alive in production.

You're probably a fit if:

- you've shipped serious backend systems in production

- you can hold your own on a customer call

- you've run LLM agents in production, or you'll ramp fast: tool calling, evals, knowing when a plain deterministic tool beats a model call

Bonus, not required: containers and CI/CD, RBAC and auditing, LangChain and LangGraph, prior customer facing or operator background.

We care more about what you've built and can build than a checklist, so skip the skills inventory and tell us about something hard you shipped.

Aquabyte is on a mission to revolutionize the ocean sustainability and efficiency of aquaculture. By making fish farming cheaper and more viable than livestock production, we aim to mitigate one of the biggest causes of climate change and help prepare our planet for impending population growth. Aquaculture is the single fastest growing food-production sector in the world, and now is the time to define how technology is used to harvest the ocean for generations to come. Through custom underwater cameras, computer vision, and machine learning we are able to quantify fish weights, detect sea lice infestations, and generate optimal feeding plans in real time.

SmarterDx builds clinical AI for one of healthcare’s most broken systems: how hospitals get paid for the care they actually deliver.

Our physician-designed clinical AI platform reviews the clinical record, understands the nuance of patient care, and helps hospitals capture appropriate reimbursement across the revenue cycle. The core problem is hard: messy clinical data, complex regulations, payer rules, medical reasoning, and real financial stakes. When we get it right, hospitals recover millions in earned revenue, reduce manual review burden, and keep clinical and revenue teams focused on higher-value work.

We’ve hit serious scale while keeping the team unusually strong and technical: MD/data scientist hybrids, Stanford LLM researchers, former Google and Amazon engineers, former ASF board member, and others who are among the best in their fields. Many teammates have been here since we bootstrapped to $1M+ in contracted revenue before raising capital.

In 2025, SmarterDx became part of Smarter Technologies through a $1.1B deal with New Mountain Capital, reaching unicorn status while continuing to operate with the autonomy, urgency, and product velocity that got us here. Before that, we raised $71M from Floodgate, Transformation Capital, and Bessemer, including a $50M Series B.

We have real product-market fit: 85+ health systems, 300+ hospital sites, rapid customer growth, and 150% YoY headcount growth (currently at ~500). Now we’re scaling the platform.

- Software Engineer (Backend) - Software Engineer (Frontend) - Site Reliability Engineer - Software Engineer Support (internal team)

Close is hiring four engineers — Sr. Backend Engineer (Python), Sr. Frontend Engineer, Site Reliability Engineer, and a Software Engineer for our Support team (internal tooling + AI systems).

We're bootstrapped, profitable, ~100 people, 100% remote US. No PMs telling you what to build — we hire people who take ownership, move fast, and care about craft.

The Support Eng role in particular is a rare one: embedded inside our Support function, shipping AI automation and internal tools with a tight feedback loop.

All roles are full-time, async-first, US time zones. https://close.com/careers

Opaxa is the AI agent platform that runs restaurant back-office operations. Not another dashboard — agents that take the work off the operator's plate and act: build the schedule and push it to action, place the order with distributors, audit the invoice for overcharges, draft the review reply. The operator approves what matters; the rest gets done.

The unfair part: the founder owns and runs a 40-location restaurant company with over 750 employee's — so Opaxa's first customer is a real, operating restaurant group with real data and real stakes from day one. Deep domain expertise is built in, and your work runs in real restaurants immediately, not after a six-month hunt for a design partner. Well-funded.

A working prototype is already built. Now I'm hiring a founding full-stack engineer to take it from prototype to production: own the architecture, the agent runtime, the backend, and the integrations the agents act through (Toast, Paycom, Sysco, and more), set the technical bar, and grow the team behind you.

You'd work directly with me — I own product, customers, and the domain; you own the AI and the build. We'd be hiring additional engineers and account managers within the first year.

You're a fit if you: - have shipped agentic systems to production — plan-and-act, not chatbots or wrappers - are a strong full-stack builder (Python and/or Node, Postgres, real infra) - use the latest AI tooling (Claude Code / Cursor) as your default want to own a whole product as the first engineer, and eventually lead

Stack: React/TypeScript, Python/Node, Postgres, the Anthropic API, integrations across the restaurant stack.

To apply: email me at colton@opaxa.ai with the most impressive agentic system you've personally shipped — what it did, what you owned, and what made it hard — plus your resume or links. I read every one and reply. Please write it yourself; if it's clearly AI-generated, I'll pass.

Tech Stack: Rust, TypeScript/React, WebAssembly, GraphQL, PostgreSQL, Kubernetes, Keycloak, ImmuDB

What happens when you get a number wrong?

In most systems, you log an error and move on. At Anyfin, a wrong number is someone's loan application.

We're a profitable Swedish fintech that helps people refinance expensive consumer loans at better rates. Small team, regulated industry, which sounds like a recipe for slow, cautious engineering. It's the opposite. The regulation sets the floor, not the ceiling. Above that floor, we experiment, ship, break, learn, and ship again.

We're building real-time credit decisions using ML models on GKE, Go and Python on the decision layer, TypeScript/Node.js on the API, React on the frontend, BigQuery and dbt for data. Interesting stack, interesting problems, and because we're small, you're close to all of it.

Hey HN! I'm Ian, one of the founders of Root Managed Services.

Root Managed Services is a managed IT services provider focused on helping businesses keep their infrastructure stable, secure, and running day to day.

We're hiring a network engineer who is excited to help with day-to-day NOC operations, client infrastructure support, alert triage, troubleshooting, and keeping systems online. This is a hands-on role for someone who enjoys digging into network issues, server alerts, firewalls, tickets, documentation, and the operational details that keep businesses running.

Root Managed Services works with small and growing businesses that need reliable IT operations without building a full internal team. That means our work spans networking, servers, workstations, monitoring, ticketing, backups, security, and client communications. We’re looking for someone who can help us improve our NOC process, respond to issues quickly, and build better operational workflows as we grow.

Stack / tools: Windows Server, Linux, firewalls, switches, VPNs, RMM tools, ticketing systems, monitoring/alerting, Microsoft 365, Active Directory, DNS, DHCP, VLANs, TCP/IP.

Applying: email me and let me know why you want to work with us.

The world doesn't need another ERP. CoPlane is building the Agentic Orchestration platform that enables enterprises to orchestrate intelligent processes across their existing systems. Founded by ex-Stripe/Segment product and tech leads, we're changing how businesses operate their backoffice - helping them scale intelligence not headcount.

We're looking for an exceptional product engineer to grow our small team of engineers that include ex-founders, open source contributors (authors of neovim and neverthrow), and architects of petabyte-scale data platforms.

We are looking for someone that wants to own product features end to end (Python + Typescript/React) but is particularly spiky on frontend and UI. You'll build a platform for billion-dollar enterprises solving their hardest, most mission-critical automation problems.

If you're excited about working at the nexus of data, automation and AI, and want to make a significant impact in an early, well-capitalized startup with large enterprise design partners, we'd love to hear from you.

Roles: Product Engineer.

Veedma is a telehealth practice for men's hormonal and sexual health. We treat low testosterone, ED, and vitamin D deficiency in men 18 and up, fully online. Cash-pay subscription covers consultations, lab panels twice yearly, prescribed medications, and unlimited messaging. Clinically Enclomiphene-only; we don't offer testosterone replacement therapy.

Founder-led: an MD urologist (CEO) and a software CTO (ex-Yva.ai, acquired by Visier). The platform is AI-native by default: both founders code in Claude Code every day, production calls OpenAI's API from Python, Akute is the EHR, Stripe handles billing.

Two founding seats, both reporting to the founders directly:

* Founding Product Engineer ($160-200k + equity). Python/Flask/Postgres/Celery. Own patient flows, EHR and billing integrations, internal clinical tooling, and the in-product LLM layer. 7+ years shipping production web apps, most of them in healthcare. Apply: https://app.dover.com/apply/Veedma/8f5e6d01-75f1-46a8-b5b7-9...

* Founding Growth Engineer ($150-190k + equity). A builder who happens to do growth. No paid budget, no agency. You ship landing pages, scrapers, creator outreach pipelines, referral loops. 7+ years in organic / partnerships growth, most of them in healthcare. Apply: https://app.dover.com/apply/Veedma/d39d76d3-e968-407c-b268-0...

Bar for both: Claude Code is your primary tool (6+ months daily, you write skills and wire up MCP servers). Healthcare in your background and where you want to stay. AI-native, not AI-curious.

Both: remote US, async-first with US-hours overlap, full-time, 1.0-1.25% equity. All roles: https://app.dover.com/jobs/veedma

TypeSafe AI (https://typesafe.ai/) is a well-funded stealth mode company making a new class of AI models which enable a reliable way to embed composable intelligence into traditional software, founded by a co-author of ChatGPT/RLHF/GPT4 (answering the questions "If AI is so smart, why are we barely automating any work? Why does today's AI always need a human-in-the-loop?").

We're especially looking for people to join our Synthetic Data research team - no previous data experience needed (synthetic or otherwise). We need strong engineers who care deeply about the end use cases and whose instincts are to NOT trust LLMs blindly and look at the reality of their generations (much more investigator in the spectrum of investigator vs optimizer).

I'm Nick, CTO & co-founder. We're Rippling, but for insurance carriers paying their sales force. Every policy sold triggers a chain of payouts across brokers, agents, and sub-agents. Today that runs on spreadsheets and legacy vendor systems and tomorrow they'll run on Chestnut. Nationwide and other major carriers have already made the switch.

Revenue is up 8x in the last year. We're backed by a16z. Founding team came out of leadership at Ethos (insuretech that recently IPO'd in January).

The work is state-heavy and correctness-critical: payouts that must reconcile with finance to the cent, dynamic agent hierarchies, retries, chargebacks, partial failures. These systems move real money and cannot drift.

You'll design schemas, build backend logic, ship UI, deploy, and own the sharp edges that show up with real enterprise customers.

Stack: Go, TypeScript/React, Postgres, Temporal, Kubernetes, AWS. We use AI aggressively and expect you to as well.

We're looking for 3–6 years on real product systems. You're thoughtful about invariants and failure modes.

Speckle is the open-source platform that makes 3D/AEC design data accessible, trustworthy, and queryable across every tool in the stack - Revit, Rhino, IFC, ACC and more. We've just launched Speckle Intelligence: ask your project models anything, trust the answer, and generate client-ready deliverables in minutes. 23 people, open-source core, enterprise tier on top, post-Series A. Repo: github.com/specklesystems

We're hiring our first Head of Delivery to own the enterprise post-sale motion: turning pilots with general contractors, owners, and large service providers into expanded production deployments. Forward-deployed role (think Palantir FDE, not SaaS customer success) - you sit inside the customer's real decision problem, make "trust the answer, take the action" true on their actual data, and feed what you learn back into product. We measure impact and not closed ticket counts.

Good fit if you've delivered technical/data products into heavy industry (AEC, construction tech, infra, or similar) and can read an enterprise's problem without a spec. AEC background a strong plus, not required. Comfortable with messy data and ambiguous orgs.
