The Role
Design and implement agentic tools, translating product needs to production, scale prototypes, improve semantic search, build evaluation pipelines.
Summary Generated by Built In

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.

In this role, you will:
  • 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.
We’ll be happy to have you on our team if you have:
  • At least five years of hands-on NLP experience.
  • Experience in information retrieval systems.
  • Strong experience in LLM prompt and tool engineering, as well as with AI agents.
  • Solid programming skills in Python and/or Kotlin (and the willingness to learn the language you’re unfamiliar with).
  • Experience building and operating production-grade software systems.
We’d be especially thrilled if you have:
  • Experience developing in Kotlin or Java.
  • Previously worked with code intelligence (e.g. AST, symbol graphs).
