Obsess over the details that separate software that works from software customers can trust: data integrity, API latency, failure modes, query performance, and the edge cases most engineers skip.
Partner closely with product and design to push past the requirements. Challenge assumptions, propose better solutions, and make sure what we build solves the actual customer problem — not just the technical specification.
Turn ambiguous user needs into clean, maintainable implementations. And advocate for the user in every technical decision.
What You’ll Bring
2+ years of production engineering experience. Early-stage startup experience strongly preferred.
Deep fluency in TypeScript and Node.js, with real opinions about API design, data modeling, backend architecture, and system reliability.
End-to-end ownership and strong product instincts. You can take a feature from idea to shipped without a frontend engineer holding your hand, and you care as much about the customer experience as the systems underneath it.
You know how to build with AI, not just use it. Tools like Claude Code, Codex, and other coding agents are a core part of your engineering workflow, and you know how to use them to dramatically increase your speed and output without outsourcing technical judgment.
A track record building complex, data-rich products backed by systems operating under real reliability and performance constraints.
Speed without the debt. You move fast without leaving behind the kind of backend mess that makes a codebase painful six months later.
High ownership. You take problems as your own and see them through — the mark of the people who thrive here.
