Rust Engineer

What MatX Is Building

MatX is seeking engineers with strong Rust skills to join our team as we create best-in-class silicon for high-performance and sustainable GenAI. We are looking for engineers to support work in these areas: Infrastructure, Performance, Runtime, Tooling/Testing, Verification.

What You'll Do Here

• Use your experience to expand upon and build new infrastructure and tooling to support hardware and/or software teams. 

• Design/implement our Rust based simulator

• Build the host-side interface library 

• Write tests that systematically explore corner cases and rare event sequences — both targeted tests and tests that use randomization to find surprises

• Work across hardware, architecture and software teams to turn specifications into concrete, testable properties

Who You Are

• Proficient in production Rust — you've shipped real systems. You're comfortable with ownership, traits, generics with bounds, and enums as sum types. You understand why Result<T, E> is better than exceptions and what the borrow checker is actually protecting you from

• 3+ years of experience

• Strong engineering fundamentals — you write clean, well-tested, well-documented code and are comfortable with build systems, version control, and CI workflows

• Comfortable with low-level systems concepts: memory layout, concurrency, bit manipulation

• Genuinely interested in hardware and willing to ramp quickly

• This is a remote (with travel) or hybrid role based in Mountain View

Bonus Points If You Have

• Experience with hardware in any capacity — FPGA projects, embedded systems, robotics, or prior roles touching hardware engineering; Accelerators are a huge plus

• Experience with foreign function interfaces — Rust FFI is ideal, but any experience crossing language boundaries is valuable

• Formal methods, model checking, or property-based testing (e.g., proptest, Kani)

• Understanding of computer architecture: pipelines, caches, memory hierarchies, on-chip interconnects

• Familiarity with ML Systems/Frameworks
