Work directly with a CTO who has 20+ years of building systems, on a product that is getting ready for launch. The LLM is at the core of it, the backend team is small, and your code goes into the first release.

We are hiring a Python backend engineer into our client's product team. Reviews here are detailed: you defend your decisions line by line and get feedback from someone who has seen most of the ways a system can fail. That is how you grow fast. The CTO also expects to hear "this is a bad idea" when it is one, with an argument behind it.

Use AI as much as you like. You own every line, whoever wrote it. You get a task and bring it back done: questions at the start, blockers raised the same day.

What you will do Own backend tasks from spec to production: API, data model, background jobs, integrations Build the layer around the LLM: checking model output, handling failures, quality tests Improve service stability before launch

What we need 4+ years of commercial development, Python as your main language. The framework is secondary You know how systems are put together: data structures and complexity, concurrency, queues, caches, transactions, indexes English Upper-Intermediate or higher: daily calls and written communication with the CTO Ukrainian or Russian for communication inside our team Nice to have: LLMs in production, asyncio, type hints and tests as a habit
