About the job
Job Title: Fullstack Engineer
Salary: $185K – $250K + 0.1% – 0.3% equity
Company Description: Founders Fund-backed applied AI startup, SF, multi-seven figure ARR in under a year
Job Description: Join a 12-person team rebuilding the foundation of one of the largest and most broken industries in the world with applied AI. This company hit multi-seven figure ARR and roughly 50% month-over-month growth in under a year, raised a 13x oversubscribed $3.8M seed round from Peter Thiel's Founders Fund, led by the partner who was early at OpenAI and Scale AI, and has capital in the bank with no urgent need to raise. You deploy to production on day one, you create your own specs, and you own your work end-to-end. This is not a role for people looking for a standard 9 to 5.
Location: San Francisco, CA (Monday through Friday in-office)
Why this role is remarkable:
- Work on genuinely hard, real-world applied AI problems including multimodal agents and complex document processing in a $280B industry that is broken and ripe for automation, backed by one of the most selective and prestigious venture funds in the world
- Join a talent-dense team where candidates who interview are consistently impressed by the technical bar, with teammates from top quant firms, top competitions, and elite engineering backgrounds who set a high standard every day
- Ship to production on day one with full end-to-end ownership of your features, work directly with enterprise customers, and have a clear path to scale into leadership as the team grows from 12 to the next stage
What you will do:
- Build and ship production-grade fullstack features end-to-end across backend Python APIs, databases, and React frontends, taking full ownership of specs and delivery from ideation through customer deployment
- Integrate and scale AI/ML systems in production including LLMs, RAG pipelines, function calling, and multimodal AI, working on the kind of applied problems that most engineers only read about
- Work hands-on with enterprise clients to integrate solutions, iterate quickly on feedback, and deliver measurable business outcomes in a fast-paced environment where 50-plus hours per week is the norm
The ideal candidate:
- 1 or more years of professional software engineering experience shipping production-grade code with a strong backend focus and clear signals of technical excellence, whether from a top-tier company, a quant firm, strong academic competitions like IMO, IOI, or ICPC, or published and applied AI work
- Strong backend engineering in Python with experience designing and shipping production APIs and databases, plus familiarity with AI/ML integration in production systems and cloud infrastructure across AWS, GCP, or Azure
- A CS or technical degree from a top program, a high-ownership mindset, and genuine excitement about working in an intense, fast-paced environment where you are expected to figure things out and deliver, not wait for direction
