at GitHub Remote - Europe

GitHub is the home for software development, where developers collaborate to build some of the world’s most important software. The security of that software is a collective problem, a responsibility that involves producers and consumers of code, open source maintainers, security researchers, and security teams. At GitHub, we want to give the community the tools it needs to secure the software we all depend on.

CodeQL is one such tool: our semantic code analysis engine that lets you query code as though it were data. CodeQL combines the latest research in compiler optimization with insights in database implementation. It understands the complex data structures inherent in code, and makes analysis available to researchers using a declarative, object-oriented query language. You can write a query to find all variants of a vulnerability, eradicating it forever. Then share your query to help others do the same.

Responsibilities:

  • Work on the development and improvement of the CodeQL language, and evaluation engine, and tooling.
  • Help to advance and evolve the core components of CodeQL:
  • Compiler - making improvements on the language, optimizer, packaging ecosystem and creating features that allow for deeper analyses.
  • Runtime - covering the efficient evaluation of queries, allowing CodeQL analyses to scale to the largest codebases in the world.
  • Tooling - helping to improve the open source extension for Visual Studio Code as well as adding further extensions and tools to ease the adoption of CodeQL by engineers and researchers.
  • R&D - investigate bleeding edge research for the development of CodeQL and the evolution of the language. Past examples include embedding deep neural networks for adaptive threat modelling; machine learning capabilities for adaptive alert ranking; research into the area of modular and incremental analysis.

Minimum Qualifications:

  • 5+ years of professional or academic experience in at least one if the following programming languages (e.g. C, C++, Java, Rust, C#, Prolog,
  • Assembly, Python, Datalog, Dart, Go, JavaScript, Ruby).
  • Experience in at least one of the following;
    • Compilers / compiler construction
    • Language design
    • Program analysis and optimization
    • Database theory

Preferred Qualifications:

  • Knowledge of high-performance interpreter construction and JIT compilation.
  • Solid understanding of modern compilers (e.g. GHC, Rust, Clang, LLVM, GCC, Roslyn, ECJ, WindRiver, EDG, PyPy etc.); how they perform and how they process highly complicated source code.
  • Experience of logic programming and declarative programming languages and techniques (e.g. Prolog, Datalog, Haskell, ML).
  • Programming language design; program analysis; static analysis; code generation.
  • Background in one of the following: Programming Language Design; Tooling; Abstract interpretation; Formal verification; Formal Methods; Program Analysis.
