Mojo Back-End Compiler Engineer

Modular is building Mojo, a new programming language for AI hardware. They are seeking a compiler engineer to design a multi-target compiler based on MLIR and LLVM, working on language features, optimization passes, and developer experience.

• Craft and implement new Mojo language features on top our MLIR-based compiler architecture.
• Dream up and realize optimization passes that make GPUs, CPUs, and accelerators sing in harmony.
• Shape the developer experience for Mojo — from syntax to performance semantics.
• Collaborate with the Modular core teams, researchers, and an emerging open-source community.
• Help define what 'next-generation language design' means in the age of AI.

• 5+ years working on compilers, runtimes, or language implementations.
• Hands-on mastery of C++ (Python fluency a big plus).
• Experience with MLIR and LLVM.
• Experience optimizing code for CPUs, GPUs or AI accelerator hardware
• Have contributed to a real-world compiler project

• Amazing Team.
• World-class Benefits (comprehensive healthcare, retirement, stock purchase, PTO, wellbeing resources, family support, learning and development).
• Competitive Compensation (strong compensation packages including RSU grants).
• Team Building Events (regular onsites and local meetups, travel 2-4 times a year).
