What MatX Is Building
MatX is on a mission to be the compute platform for AGI. We are developing vertically integrated full-stack solutions from silicon to systems including hardware and software to train and run the largest ML workloads for AGI. MatX is seeking silicon micro-architects and design engineers to join our team as we create best-in-class silicon for high-performance and sustainable GenAI. Successful candidates for these roles will be responsible for delivering performant and functionally accurate silicon for MatX products across compute, memory management. High-speed connectivity and other key technologies.
This is a senior, hands-on individual-contributor (IC) technical leadership role. You will own the verification strategy for the compute datapath and drive it across two complementary worlds: conventional silicon verification (SystemVerilog/UVM, assertion-based, formal) and Rust-based software–silicon co-simulation. You will set direction, raise the bar on quality and coverage, and provide technical guidance to verification engineers working in both styles — including early-career engineers growing into independent owners.
What You'll Do Here
Own and drive the end-to-end verification strategy — across block, subsystem, and SoC levels — spanning conventional (UVM/SV, assertion-based, formal) and Rust SW–silicon co-simulation approaches
Who You Are
Bonus Points If You Have
10+ years of silicon verification experience
Experience with the numerics of compute / matrix / vector-math datapaths (floating-point pipelines included) — enough to hold substantive conversations with architects
Production Rust experience, or experience standing up Rust-based co-simulation / co-verification flows
Hands-on experience in an abstracted / functional HDL ecosystem (Bluespec BH/BSV, Chisel, etc.)
Familiarity with emulation and prototyping platforms; participation in silicon debug and bring-up
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 - $120,000 - $275,000 + equity
Mid Career - $175,000 - $450,000 + equity
Senior Career - $275,000 - $600,000 + equity

Provide technical direction and mentorship to verification engineers working in both conventional silicon-verification and Rust co-simulation roles; grow early-career engineers into independent owners of their areas
Make and own the methodology calls — where conventional UVM/SV, Rust co-simulation, and formal each fit best — and drive verification strategy accordingly
Drive verification across the seams: partner with SoC integration, formal verification, and the software/modeling team to turn architectural specifications into concrete, testable properties and coverage closure
Plan and drive intermediate and sign-off reviews on test plans, execution progress, and verification closure toward design freeze and tapeout
Build and curate verification infrastructure and regressions the broader team can adopt and extend
8+ years of silicon verification experience, including at least one tapeout owning a block's or subsystem's verification — concept-to-silicon experience driving verification from an architecture and/or design specification to production silicon
Strong software aptitude, with proven experience crossing language boundaries while driving verification goals — comfortable working across Rust, Python, and C/C++ as the task demands
Deep, hands-on expertise in conventional verification — SystemVerilog/UVM, assertion-based verification — with comfort across both formal and simulation-based verification
Able to lead across methodologies: you can guide engineers in conventional silicon verification and in Rust-based SW–silicon co-simulation, and set strategy that applies each where it fits
Either prior experience verifying designs expressed in abstracted / high-level HDLs (Bluespec, Chisel, etc.), or the ability to ramp quickly on Bluespec and drive verification strategy for designs written in it
Strong leadership and communication — you drive sign-off conversations, mentor engineers, and partner cleanly across architecture, design, SoC, and software
Background in AI accelerator, GPU/TPU-class, or other high-throughput compute datapath verification
