We are looking for a Senior Software Engineer to join one of the distributed software engineering teams responsible for building and expanding code analysis engines and agents  this role you will work in one of the following areas, selected based on your own experience and interests, and the needs of the organization at the time of hiring:

• Code analysis
  :
  • Maintaining detection support for multiple programming languages, including:
  • building source code extractors that translate code written in each language into data that CodeQL can understand, keeping up with the latest version of each supported language
  • writing and maintaining queries in the CodeQL query language that accurately detect security vulnerabilities and undesirable coding patterns
  • building analysis libraries in the CodeQL query language that reason precisely about the semantics of programming languages, supporting the development of queries across all languages
  • experimenting with and robustly evaluating LLM‑powered detection engines and integration between LLMs and traditional static analysis
• Foundations
  :
  Developing QL, the query language powering CodeQL analysis, and its underlying query compiler and evaluator within the CodeQL CLI. Expanding the expressive power of the CodeQL query language and speeding up the performance of the underlying query engine, empowering other teams to write high‑quality analysis, and ensuring that CodeQL scales to the largest codebases in the world.

In any of the above tracks, you will work closely with various engineering teams, product managers, designers, and technical writers that build different aspects of the code scanning product, to influence product direction and deliver features to users, with clear focus on quality, reliability, and user experience. You will engage with internal users and external users (both from enterprise customers and the open‑source community) to help them succeed with the product.
