The posting

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.

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.

What you will do:

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.

What you bring to the table:

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

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
