The role

At JetBrains, code is our passion. Ever since we started back in 2000, we have been striving to make the world's most robust and effective developer tools. By automating routine checks and corrections, our tools speed up production, freeing developers to grow, discover, and create.

We are now building services and agentic tools that provide AI coding agents and end users with deeper context about codebases. Our code retrieval service already delivers meaningful improvements in agent speed and task performance, and we aim to push this further - extracting richer insights than snippets alone at the scale of several hundred thousand repositories.

We are looking for an AI Engineer who can design and implement agentic tools from scratch, bring them to the end users, and make coding with agents smarter, faster, and more reliable.

What you'll do

  • Translate product needs into agentic tools and services and ship them to production.
  • Scale prototypes to large numbers of users.
  • Improve and test our semantic search service.
  • Build evaluation pipelines for code retrieval and coding task performance.
