Rust SW-Silicon Co-verification Engineer at MatX in Mountain View, CA

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. You will write Rust tests that verify our software models and hardware design behave identically and match the specification.

Your tests and tooling will exercise the chip's software model and hardware design side by side, catching mismatches before they become silicon bugs. If you've ever wished your knack for writing correct, thorough Rust could be applied to something where correctness has million-dollar consequences, this is the role for you. You do not need prior hardware or verification experience to apply — if you know Rust, we will teach you the hardware side.

What You'll Do Here

• Write Rust tests that verify our software models and hardware design agree with each other and with the specification
• Build test infrastructure in Rust that makes it easy to add new tests and run them at scale
• Develop and maintain harnesses that connect your tests to our hardware
• Write tests that systematically explore corner cases and rare event sequences — both targeted tests and tests that use randomization to find surprises
• Work with architects and design engineers 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
• 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 on chip verification
• This is a hybrid role that will require you to work from our Mountain View, CA office 3 days a week on Tuesday through Thursday

Bonus Points If You Have

• Experience with hardware in any capacity — FPGA projects, embedded systems, robotics, or prior roles touching hardware engineering
• Experience with foreign function interfaces — Rust FFI is ideal, but any experience crossing language boundaries is valuable
• Experience with Bluespec (BH or BSV)
• Formal methods, model checking, or property-based testing (e.g., proptest, Kani)
• Understanding of computer architecture: pipelines, caches, memory hierarchies, on-chip interconnects
