Job summary

Modular is hiring a Hardware Enablement engineer to broaden support for new accelerator architectures across the software stack, from Mojo to MAX model serving. You’ll work with cross-functional teams, learn vendor toolchains, and help improve portability and performance on cutting-edge hardware.

The role emphasizes collaboration, rapid learning, and hands-on kernel and compiler work, with opportunities for onsite alum in Los Altos and remote options for senior staff.

Qualifications

• 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)
• 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

Responsibilities

• Implement and validate support for new hardware architectures across the Modular stack, working under the guidance of senior engineers on the team
• Write and optimize Mojo kernels targeting novel accelerator architectures, with a focus on correctness first and performance iteration
• Contribute to cross-team efforts improving portability infrastructure, tooling, and debugging workflows for new target hardware
• Collaborate with hardware vendor engineers to understand target platforms, build integration tests, and triage platform-specific issues
• Develop working knowledge of new hardware platforms — including ISA documentation, memory hierarchies, and vendor toolchains — and share findings with the team through demos and write-ups
• Participate in company events such as on-sites and hackathons, contributing to a collaborative and open engineering culture
