Founding Engineer, Backend & AI
Base + equity
You'll own the backend infrastructure and AI inference layer that powers Compose, Discover, and Reporter. This is the most consequential engineering role at the company — the systems you build will define what the product can do for the next decade.
What you'll do
- Architect and build the AI inference layer on Anthropic's Claude API — including prompt construction, output validation, source attribution, and zero-data-retention guarantees.
- Own the Compose drafting pipeline end-to-end — corpus ingestion, voice-signature extraction, draft generation, source-grounded citations.
- Build and operate the Postgres-based platform on AWS, with deliberate emphasis on observability, audit logging, and tenant isolation.
- Set technical standards for the engineering team — code review, testing philosophy, deployment cadence, on-call rotation.
What we're looking for
- 5+ years of backend engineering experience, with substantial production experience in Python (FastAPI, SQLAlchemy) and Postgres at scale.
- Hands-on experience building products on top of LLM APIs — shipping production systems with proper output validation, cost controls, and graceful degradation.
- Strong opinions about API design, data modeling, and operational excellence, held loosely.
- The ability to write clearly about technical trade-offs in long-form documents.
