Requirements

  • You have at least 3 years of professional experience with C/C++ and 1+ year of hands-on experience with Rust.
  • You are experienced with FFI tools (bindgen, cxx) and unsafe Rust for C/C++interoperability.
  • You bring experience testing migrated code (unit/integration/fuzz tests).
  • You demonstrate solid understanding of systems programming (memory management, concurrency).
  • You are skilled at refactoring legacy code and documenting migration steps.
  • Prompt engineering experience is a strong plus.
  • Your level of English is advanced (C1) or above.
  • You are ready to learn new methods, able to switch between tasks and topics quickly and sometimes work with challenging, complex guidelines.
  • Our freelance role is fully remote so, you just need a laptop, internet connection, time available and enthusiasm to take on a challenge.

Benefits
Why this freelance opportunity might be a great fit for you?

  • Take part in a part-time, remote, freelance project that fits around your primary professional or academic commitments.
  • Work on advanced AI projects and gain valuable experience that enhances your portfolio.
