Senior Software Engineer - YC-backed AI Platform San Francisco (preferred) / Remote - with monthly SF visits
Our client, a YC-backed startup with a recent $6M seed round, is on a mission to empower non-technical founders to turn ideas into scalable software businesses. Their platform bridges the gap between AI-generated code and production-ready products - delivering not just the build, but the infrastructure, tooling, and go-to-market support to help new companies succeed.
This is a rare opportunity to join a high-caliber founding team (ex-serial founders with a decade of working together) and work on deep, complex engineering problems that make sophisticated tech invisible to end users.
What you’ll do:
Design and build full-stack features from scratch - front-end, back-end, infra, and architecture
Architect modular, reusable systems that scale
Work closely with product and design to ship quickly without sacrificing quality
Collaborate with a small, senior team that values high autonomy and zero fluff
Keep pace with the latest technologies and contribute to technical direction
Take ownership end-to-end - no “just my piece of the stack” mentality
What we’re looking for:
4-10 years’ experience in software engineering, with strong CS fundamentals
Proven 0-to-1 product experience (ideally as a Founding Engineer or early hire at a VC-backed startup)
Fluency in
TypeScript
and
React
(React Native a plus)
Experience with
AWS ,
Docker ,
Postgres , and scalable architectures
Ability to operate without heavy reliance on AI coding tools - you can code and architect from scratch
Strong communicator who thrives in high-autonomy, fast-paced environments
Based in or willing to relocate to SF (remote possible for exceptional candidates who can attend 3-day on-site sprints monthly)
Be part of a
high-bar engineering culture
- every teammate is senior-level or above
Ship products that help thousands of founders bring their ideas to life
Competitive comp - salary at the 90th percentile for top performers, plus meaningful equity
Work directly with the founders to shape the company’s technical future
No bureaucracy, no layers - just a flat, hands-on team moving fast
If you’re the kind of engineer who loves building from the ground up, hates red tape, and wants to work with an elite team solving ambitious problems, we should talk.
