About the role

Mojo is our secret sauce, spell-book, and Mjolnir , a new programming language that blends the soul of Python with the raw, elemental power of C. It’s designed to unlock every ounce of performance from modern AI hardware, while still being human-friendly and beautifully expressive.

What they're looking for

  • 3+ years working on compilers, runtimes, or language implementations
  • Hands-on mastery of C++ (Python fluency a big plus)
  • Familiarity with compiler development frameworks such MLIR and LLVM
  • Understanding of type systems, compiler optimization theory, and language semantics. (those who read the Pierce’s Types and Programming Languages, and can present a proof, will skip an interview)
  • Contributions to Clang, GCC, Swift, Rust, Dart, or another real-world programming language implementation
  • Experience with HPC or accelerator ecosystems (CUDA, SYCL, OpenCL, etc.)
