About this role
JetBrains is an AI startup focused on building innovative tools for creators. They are seeking a Research Engineer to develop AI product features, improve system reliability, and track advancements in the AI space.
Responsibilities:
- Ship AI product features that combine engineering and ML
- Build and improve agent workflows (tooling, retries, guardrails, fallbacks)
- Improve the latency, cost, and reliability of our systems
- Track what’s new in the AI space (agent teams, methods, tooling) and turn it into shipped products
- Build self-improving loops: systems that run experiments, learn from feedback and evals, and improve the product over time
Requirements:
- Have shipped real systems, not just demos or prototypes
- Have built software with LLMs (structured outputs/function calling, tool use, reliability work)
- Have built agents (multi-step workflows that call tools, keep states, and handle failures)
- Have set up evals to track quality (tests, regression checks, eval harnesses)
- Feel comfortable moving fast, iterating, and owning outcomes end to end
