## About the role

ML developers today face significant friction in taking trained models into deployment. They work in a highly fragmented space, with incomplete and patchwork solutions that require significant performance tuning and non-generalizable, model-specific enhancements. At Modular, we are building the next generation AI platform that will radically improve the way developers build and deploy AI models.

## What they're looking for

- 2+ years of experience in high-performance computing, compiler engineering, or related domains in industry or research
- Proficiency in C++ and experience working in complex, multi-component software systems
- Hands-on experience with at least one heterogeneous programming model (CUDA, SYCL, OpenCL, or similar), either as a user or contributor
- Some exposure to non-GPU accelerator architectures (DSPs, NPUs, or other hardware accelerators) is a strong plus
- Curiosity and willingness to learn new hardware platforms quickly, comfortable reading architecture manuals and vendor documentation
- A collaborative, team-oriented attitude and alignment with our culture
