Python Developer (FastAPI + LLM) European hosting provider launches a new B2B product - a multi-agent LLM system that generates websites on demand. The product is at MVP stage.

📍Candidate location: Ukraine.

✔️ What you'll do: 🔹 Build a multi-agent system where a planner agent breaks down user requests and a code agent generates working websites — you'll design how these agents talk to each other and to the LLM 🔹Write and iterate on prompts and tool schemas so the LLM reliably picks the right actions and returns clean, parseable output (including handling "messy" JSON from the model) 🔹 Build the backend that powers it: FastAPI, Celery + Redis for async job orchestration, PostgreSQL for state and history 🔹 Spin up and manage isolated Docker sandboxes where generated code actually gets built and tested — including recovery when a build or container fails 🔹 Push real-time build progress to the frontend as it happens 🔹 Own reliability end-to-end: retries, idempotency, graceful recovery from LLM/container/network failures — this is an MVP, so a lot of these patterns you'll be designing from scratch

✔️ What we expect: 🔹 3 years of experience. 🔹 Strong Python (async/await, typing, Pydantic) and FastAPI experience 🔹 Queues and data: Celery + Redis, PostgreSQL 🔹 Docker and Git in daily work 🔹 English — reading documentation and APIs ✔️ Nice to have: 🔹 Experience with LLM (tool/function calling, structured output). Not required — we'll train you on the project.

✔️ What we offer: 🔹 Remote work in Ukraine (office in Khmelnytskyi — optional) 🔹Paid vacation and sick leave 🔹 Real impact on product architecture from scratch 🔹 Modern stack + LLM tasks 🔹 B2b contract
