Rust Engineer

MatX•Mountain View, CA

30d•$120,000 - $475,000•Hybrid

About The Position

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.

Requirements

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 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

Nice To Haves

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

Responsibilities

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
