About the role
TL;DR
Own and ship full-stack product features with a backend-first approach.

- •You'll own complete product slices end-to-end.
- •You're not a specialist who hands off at the API boundary.
- •You think in user outcomes and delivery units, and you're reliable: your code handles edge cases, your APIs have clean contracts, and the work you ship stays shipped.
- •Key Responsibilities Own product delivery
- •take features from spec to production, backend-first but covering frontend and integration where needed Build and maintain backend systems
- •product APIs, data pipelines, and core infrastructure on our Python/FastAPI/Postgres stack Build with LLMs and agents
- •ship product features with significant LLM integration; contribute to the voice agent backend and information extraction systems Work across the stack
- •ship workable React/TypeScript frontend for product features; not a frontend specialist, but comfortable and pragmatic Collaborate with product and design
- •translate ambiguous requirements into concrete shipped work; be the engineer who unblocks, not the one who waits Maintain quality at speed
