Factory | Security Engineer | Onsite in San Francisco | Full-time

Come work on my team! (We’re hiring lots of engineers right now, but I’m biased toward my own group today.)

Factory builds software development agents that accelerate the world's largest enterprise engineering teams. We're helping customers including Nvidia, Adobe, Adyen, Klarna, and Ernst & Young turn their engineering organizations into autonomous development systems — shipping code, reviewing PRs, running tests, and deploying continuously.

We're seeking a talented Security Engineer to join our team. In this role, you will play a critical role in developing and maintaining the security foundation of our platform. You will conduct in-depth code reviews, implement security best practices, and influence the overall security strategy. Your expertise in TypeScript, Python, Kubernetes, CI/CD, and terraform orchestration will be crucial in identifying and mitigating potential security vulnerabilities.

MintMCP | Founding Engineer / Founding GTM | SF Bay Area (HYBRID)

MintMCP gives IT one place to roll out AI agents easily, providing security teams governed identity, access, and visibility while engineering teams connect MCP tools, LLMs, and coworker agents.

We also doubled our team in the last 6 weeks from 6 to 12 FTEs, and almost everyone is a seasoned startup vet at staff or principal level.

Chariot Claims | Full-Time | Various Staff+ Engineering Roles | REMOTE (US) | https://chariotclaims.com

We recently raised series A and are hiring driven engineers who have strong product sense, leverage AI effectively, communicate well, and want to build technically interesting products that benefit the everyday person.

You'll join as the lead product engineer on greenfield projects that are scoped to take us from 1-100. We're building a verticalized factory for claims. ex:

* agentic legal case origination agent - responsible for validating things like privacy violations, research existing case law to find new cases for us to operationalize

* real-time claims processing - claim quality / fraud detection at scale, harnessing regulatory requirements for novel approaches

and much much more

Chariot Claims is a platform that helps everyday people find, file, and manage legal claims without any hassle. We proactively identify companies accused of breaking the law and violating consumer rights, and fight so they can get the compensation they may be entitled to. We partner with law firms to execute on legal proceedings.

Our team is fully remote, with hubs in Berlin, NY, DC, and (soon) SF. Onsites for the team in the US every ~2 months, and curated offsites in a beautiful location 2-4 times a year with your +1.

Seeking US BASED Freelancer Only — Co-Founder - Equity‑only until MVP - Long Term with Follow-on Projects - Remote (US)

Building CaseLight, a local‑first investigative evidence platform for private sector, corporate and insurance investigators. I’m a 24 year former federal LE & current private investigator founder with the full product spec, workflows, and roadmap ready — just need a strong engineer to help punch out the desktop MVP. Front end UI is already operational.

Looking for: C#/.NET desktop dev, SQLite, local encryption, packaging/installers, clean productivity UI. Must be US‑based. Must be able to ship independently.

Offer: Equity‑only until MVP launch. I have solid GTM, trust network and traction in an otherwise insular market. There is no product like this on the market and the industry is begging for it. Serious builders only.

What you’ll build: case management, evidence ingestion, tagging/search, timeline, encrypted local storage, hashing, dual timestamp, export/report modules.

Drop questions or GitHub + relevant experience to info@getcaselight.com

Sunspell | Founding Engineer | New York, NY | ONSITE | Full-time | https://sunspell.fm/careers/founding-engineer

Six-person venture lab in New York. We build our own products. A studio arm does client work, is profitable, and pays for the rest.

Our founder ran her own design studio and was the founding design partner on Partiful, on Sentropy before Discord bought it, on Goldcast before Cvent, on Make before Celonis, and on Descartes Labs. She builds here now instead of for other people.

You would own the production application around our intelligence layer. Architecture, frontend, backend, Postgres, durable execution state, retries and idempotency, permissions, deploys, and the data-heavy interfaces people work inside all day: tables, relationships, filters, history, approvals. React and TypeScript at depth, Node or Python behind it. We write a lot of MCP servers and build with Claude Code daily.

Seven-plus years shipping, hands on code within the last year. Design and engineering sit in the same room here. There is no handoff.

Most people who apply like the words "founding engineer." We are looking for someone who has already started something of their own.

Ownership. You should own a piece of what you build here. We are not going to post a percentage, because the honest answer depends on what you end up carrying, and we would rather work that out with you than hand you a number that pretends to be precise. It is a conversation, it is flexible, and we intend it to be fair.

We are six people. Nothing you build goes through a committee before it ships. Nothing you break, you fix alone. We are a tight team today and we are looking to double it by the end of the year.

Please send your resume or GitHub, plus the most ambitious thing you have built mostly on your own. Rough work that worked beats polished that never shipped.

If this is not you but a name comes to mind, please pass it along. :)

InfoHawk | Software Engineer | London, UK or NYC | REMOTE (UK or US), occasional onsite | Full-time | https://www.infohawk.com

Fraud reaches people through ads, cloned brand sites, counterfeit shops and AI-generated video, and it moves faster than any manual review. InfoHawk detects it while it is still running, correlates it across platforms and formats, and surfaces it early enough for our customers to act. We are a small team of engineers plus security, privacy and fraud specialists. Pre-seed, $2.25M led by Moonshots Capital: https://www.infohawk.com/news/2026-06-08-pre-seed-funding-an...

You’d own how data gets in: scrapers and collectors that survive source changes, official APIs where they exist, undocumented endpoints where they don’t. Sources break constantly. Can you figure out how to use AI to spot the change and adapt automatically? Stack: TypeScript, Node, SvelteKit, Postgres, Playwright, heavy AI-assisted development.

We’re looking for ~3-5 years building scraping or integration systems in production, but if you’re a great engineer who doesn’t tick every box we’d still like to hear from you. UK-based for London, US-based for NYC; we cannot sponsor visas. Two of our three founders are engineers, one in each city, and you’ll work with them directly.
