Open positions
Hardware Tools Engineer
Builds and evolves the language, compiler, and tooling that MatX hardware engineers use daily — chiefly the open-source Bluespec compiler (Haskell) plus Rust-based hardware libraries, simulators, and design/verification flows — so architects, designers, and verification teams on the AI chip can move faster.
Design Verification Engineer - Compute
Design Verification Engineer at MatX, an AI-chip company, owning subsystem- and chip-level verification of high-performance AI accelerator silicon: building testbenches and tests, driving coverage closure, and leading verification sign-off through design freeze and tapeout using SystemVerilog/UVM, formal and simulation, plus Python/C++.
Microarchitect and RTL Designer - Compute
Own micro-architecture and RTL for the compute subsystem of MatX's AI accelerator chips — from spec through area/timing closure, design freeze, and tapeout — collaborating with verification, DFT, and physical design teams. Core tech: SystemVerilog, Bluespec, Python, C/C++, synthesis and sign-off flows. Mountain View HQ or remote.
SOC Integration Engineer
A silicon SOC integration engineer who stitches subsystems into the full-chip top-level RTL for MatX's AI training chips, building automation for on-the-fly SOC RTL generation and aligning clock/reset, timing, and floorplan connectivity with physical design. Core tools: SystemVerilog, Python/Perl, and SOC integration/verification flows.
Software Engineer, AI Tooling
Builds the AI agent infrastructure at MatX, a custom AI silicon company: making coding agents first-class users of internal infra with their own identities and audited access, running them in ephemeral VMs and no-egress sandboxes, and maintaining a company knowledge base pulled from the monorepo, design docs, and Slack.
