BNamericas is hiring
Senior Full-Stack Engineer AI Native
- 8+ years building and operating production web applications end to end, backend-weighted, with a track record of owning systems rather than tickets.
- Strong Python in production. FastAPI is what we use; Django, Flask or similar is fine if you can move across.
- Solid relational data modelling and migrations against live data.
- Real frontend experience, and the ability to ship usable UI without a design team. Whichever framework you come from, what matters is that you work comfortably on both sides of the line.
- Hands-on experience getting LLM-backed systems into production: agent or graph orchestration, RAG, prompt and context design, and evaluating model output rather than trusting it.
- Fluent daily use of Claude Code or an equivalent agentic coding tool, with a clear view of where it helps and where it doesn't.
- Production experience on a major cloud. We are on AWS: containers, background jobs, secrets, logs, and debugging things that only break in prod.
- Autonomy. You'll get context and a goal, not a decomposed backlog.
- Documentation creation that let someone else pick the work up.
- Professional English
- Connection during LATAM (Chile) Business hours
