Rust Engineer - Mountain View, CA, United States
$175,000 - $362,500 USD yearly
Originally posted 16 July 2026 by the employer.
About the role
MatX is seeking engineers with strong Rust skills to build silicon for high-performance and sustainable GenAI across infrastructure, performance, runtime, tooling/testing, and verification. You will design simulation infrastructure, host-side libraries, and verification tooling to support hardware and software engineering teams.
What you'll do
- Expand upon and build new infrastructure and tooling to support hardware and software teams. - Design and implement a Rust-based simulator. - Build the host-side interface library. - Write tests that systematically explore corner cases and rare event sequences using targeted tests and randomization. - Work across hardware, architecture, and software teams to turn specifications into concrete, testable properties.
What you'll need
- 3+ years of engineering experience with proficiency in production Rust, including shipping real systems. - Experience with Rust ownership, traits, generics with bounds, and enums as sum types. - Strong fundamentals in build systems, version control, and CI workflows. - Understanding of low-level systems concepts, including memory layout, concurrency, and bit manipulation. - Interest in hardware systems and ability to work across technical domains.
Nice to have
- Experience with hardware in any capacity, such as FPGA projects, embedded systems, robotics, or accelerators. - Experience with foreign function interfaces (FFI), specifically Rust FFI or crossing language boundaries. - Experience with formal methods, model checking, or property-based testing (such as proptest or Kani). - Understanding of computer architecture concepts including pipelines, caches, memory hierarchies, and on-chip interconnects. - Familiarity with ML systems and frameworks.
Skills: Rust, simulator, host-side interface library, hardware/software teams, ML Systems/Frameworks
