Job summary

MatX Inc. seeks engineers with strong Rust skills to verify our silicon through software models and hardware design. You will write Rust tests, build scalable test infra, and develop harnesses linking tests to hardware.

The role blends software and hardware verification with a focus on correctness and robust tooling. You will work in a hybrid setting at our Mountain View, CA office, three days a week, collaborating with architects and design engineers.

Qualifications

• Proficient in production Rust with ownership, traits, generics, and enums
• Strong engineering fundamentals: clean, well-tested code with 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

Responsibilities

• Write Rust tests that verify software models and hardware design agree with the specification
• Build test infrastructure in Rust to add tests and run them at scale
• Develop and maintain harnesses connecting tests to hardware
• Write tests that explore corner cases and rare event sequences including randomized tests
• Collaborate with architects to translate specifications into testable properties

Job description

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 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

Compensation

The US base salary for this full-time position is determined based on a variety of factors including role, experience, location, job-related skills, and relevant education and training. Career length is only a guideline for compensation.

• Early Career - $160,000 - $275,000 + equity

• Mid Career - $175,000 - $400,000 + equity

• Senior Career - $250,000 - $600,000 + equity

What We Offer

• Time off: 4 weeks PTO (accrued) + 12 company Holidays + up to 3 weeks remote work

• Health: Company-subsidized Medical (Kaiser or Anthem) for employees & dependents, Guardian Dental and Vision insurances for employee & dependents, and life insurance (employee only), plus HSA and FSA offerings via Lively. See attached benefits 1-pager and full benefits guide for more info on benefits.

• Financial Wellbeing: Choose from Roth IRA/ 401K (or both) retirement plans with up to 5% company contribution to 401K (even if you don't contribute). Also, 100% company-paid life insurance (up to $300K) and long-term disability insurances.

• Professional Development: $1500 Professional Development Budget (per year)

• Team Meals: MatX provides onsite team lunch & dinner Monday - Friday, with your choice of ordering via WeBox, Specialty’s or via our reimbursement system

• Commute on Us: Commute on our company Uber account, or reimburse your train rides. Either way, we pay 100% for your daily commute.

• MatX E[x]tras: $50/mo to use on the perk you value most

• Cell & Internet Reimbursement: $35/mo for cellular and $40/mo for wifi

• Mental Wellbeing: 100% paid mental health benefit via SpringHealth and Guardian EAP.

• Support to Parents: Up to 12 weeks paid parental leave regardless of path to parenthood, 10 weeks pregnancy disability leave, flexible return-to-work hours, and Benepass reproductive health & parental benefit.

• AI Resources: Up to $20K/month plus a dedicated internal AI Tooling Team to support your productivity
