Instrumentl
Senior (and above) Backend Engineer | REMOTE (US + Canada)
hn · REMOTE (US + Canada)
Exceptional technical match with deep Python/FastAPI expertise, proven ability to build AI features end-to-end from prototype to production (demonstrated at Addie and Rubercubic), and direct experience with the exact stack (Python, FastAPI, Langchain, Postgres, Redis, GCP). Strong founding engineer background shows ability to own architecture and shipping decisions. Only minor gap is lack of explicit Qdrant vector DB experience, though RAG expertise suggests quick ramp-up.
Hook: Your backend AI role is a natural fit for someone who just built a real-time voice AI platform end-to-end using FastAPI and LangGraph—and scaled it to production across 10+ countries in month one.
Missing: Qdrant vector database
