At Modular, a Qualcomm company , we’re on a mission to revolutionize AI infrastructure by systematically rebuilding the AI software stack from the ground up. Our team, made up of industry leaders and experts, is building cutting-edge, modular infrastructure that simplifies AI development and deployment. By rethinking the complexities of AI systems, we’re empowering everyone to unlock AI’s full potential and tackle some of the world’s most pressing challenges.

If you’re passionate about shaping the future of AI and creating tools that make a real difference in people’s lives, we want you on our team. You can read about our culture and careers to understand how we work and what we value.

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. We are searching for a compiler engineer who can help make Mojo the best language for heterogenous programming for CPUs, GPUs and hardware accelerators. You will be designing a multi-target compiler technology stack, based on MLIR and LLVM. You will be collaborating with kernel authors and hardware engineers to get best performance for each hardware target.

We are a small team with no internal boundaries. You will end up touching everything in the Mojo land, from language to IR to codegen to SDK and user experience.
