Cross-Platform C++ Build & Integration Engineer (CLion)

At JetBrains, code is our passion. Ever since we started in 2000, we have striven to make the strongest, most effective developer tools on earth. Our tools speed up production by automating routine checks and corrections, freeing developers to grow, discover, and create.

CLion is JetBrains’ cross-platform C and C++ IDE, trusted by hundreds of thousands of developers worldwide. It offers powerful code analysis, refactoring, debugging, and build configuration tools that help developers write high-quality code more efficiently.

CLion comes with a variety of native development tools – including LLDB, GDB, CMake, Ninja, and Python support – fully integrated and ready to use out of the box. By joining us, you’ll become part of the team responsible for the cross-platform engineering behind these tools, working on a range of projects like building and packaging, or fine-tuning for performance and compatibility on Linux, macOS, and Windows.

You’ll work at the intersection of C++ development and cross-platform build engineering, collaborating with the team to maintain and improve CLion’s bundled native tools.

In this role, you will: 

• Maintain and improve the cross-platform build process for native tools shipped with CLion.
• Update, patch, and adapt tools like LLDB, GDB, CMake, Ninja, and Python when needed.
• Implement CI/CD automation for these tools, while keeping ownership distributed within the team.
• Ensure builds are reproducible, stable, and optimized on Linux, macOS, and Windows.
• Collaborate with product and platform teams to integrate tools into CLion.
• Document build and packaging workflows so others can contribute and debug.
• Pair with other developers during major tool upgrades to share knowledge and reduce the bus factor.

What we’re looking for 

We'd love to have you on our team if you have:

• Extensive C/C++ programming experience.
• A solid understanding of how binaries, linking, and debugging work on multiple platforms.
• Experience with cross-platform build systems (like CMake or Ninja) and compiler toolchains (like GCC, Clang, and MSVC).
• Familiarity with the packaging and distribution of native tools and libraries.
• Comfort with scripting languages (like Python, Bash, and PowerShell) for automation.

We'll be especially thrilled if you have:

• Prior experience working on IDEs, compilers, debuggers, or developer tools.
• Knowledge of continuous integration systems (like TeamCity, GitHub Actions, Jenkins, etc.).
• Experience contributing to open-source build or toolchain projects.
• Experience with Java or Kotlin development, or an interest in learning these languages.
