At JetBrains, code is our passion. Ever since we started, back in 2000, we’ve been striving to make the strongest, most effective developer tools on earth. Today, AI-powered assistance and agents are becoming a core part of how developers work in our IDEs.

We’re building multi-step coding agents that can understand large codebases, plan changes, call tools, and iterate with the user. As a Research Engineer in the Agentic Models team, you’ll be responsible for the models, training loops, and evaluation pipelines that power these agents.

You’ll work at the intersection of SFT and RL‑style post‑training, and product‑driven evaluation, using our distributed GPU and MapReduce clusters to ship models into JetBrains products.

As Part Of Our Team, You Will

• Design, implement, and maintain SFT and RL post‑training pipelines for multi‑step coding agents.
• Train and adapt LLMs for agent workflows, including planning, tool use, and multi‑step i...
