JetBrains is hiring a Staff or Senior AI Engineer for its AI for Code team, which builds coding agents. The role turns internal models such as Mellum2, plus open-weight models, into production agents: model training and fine-tuning, context engineering, tool use, evaluation suites, and feedback loops from real usage. The posting asks for strong software engineering, hands-on LLM product experience, evaluation and benchmarking practice, and comfort with ambiguous, multi-iteration work. It is based in one of nine listed cities, and shipping features rather than isolated research is the stated goal.
