  • Work with Mesa maintainers and kernel maintainers through code review and open source collaboration.
  • Translate hardware vendor and client requirements into upstream-compatible technical solutions.
  • Balance upstream correctness, performance targets, vendor constraints, and client deadlines while maintaining code quality.
  • Explain complex GPU and driver architecture decisions to product teams and clients.
  • Review patches, participate in technical discussions, and help shape driver architecture decisions.

  • DRM fundamentals, including GEM/buffer management, dma-buf/prime sharing, fence and sync objects, and GPU job submission paths.
  • Mesa architecture awareness, including Gallium and driver structure.
  • Basic understanding of how userspace drivers interact with the kernel.
  • Strong C and C++ skills, including pointer arithmetic, memory management, and kernel-style coding.
  • Git experience with mailing list patch workflows, not just GitHub pull requests, is preferred.
  • Ability to read specs and documentation independently is preferred.
  • Comfort working in large unfamiliar codebases is preferred.
  • Open source contribution mindset, including public code review and upstream-first collaboration, is preferred.
  • Existing Mesa or kernel patch history is preferred.
  • Experience with a specific GPU family such as ARM, AMD, or Intel is preferred.
  • Python experience for tooling and scripting is preferred.
  • Rust programming skills are preferred.
  • Understanding of KMS fundamentals or Wayland clients is preferred.

Benefits

  • Biannual wellness assessments with a trained mental health specialist.
  • Conference attendance expenses covered, with encouragement to speak.
  • Open source time to contribute to projects you care about.
