Microarchitect and RTL Designer - Compute

MatX•Mountain View, CA

23d•$175,000 - $600,000

About The Position

MatX is building hardware to make the world’s best AI models run as efficiently as physics allows. The compute subsystem implements the core numerics and associated control and data paths needed to accelerate target machine-learning workloads. The Microarchitect and RTL Designer owns microarchitecture and RTL for compute blocks end to end. The role contributes to MatX’s silicon architecture-to-design methodology, developing scalable solutions across blocks, subsystems, and full-chip design. It may own entire subsystems, subsets, or chip-level silicon design deliverables from microarchitecture through sign-off-ready design. The role plans and drives intermediate and sign-off reviews of specifications and execution progress, and works toward area and timing closure for milestones such as design freeze and tapeout. It works closely with verification, DFT, and physical-design co-owners to deliver strong performance, power, and area results. The position requires access to information subject to U.S. export controls. Employment is contingent on being able to perform the job in compliance with those laws without obtaining an export-control license.

Requirements

At least 5 years of silicon design experience.
Tapeout experience, demonstrating end-to-end ownership of a design through multiple generations.
Ability and willingness to ramp up on Bluespec, a functionally rooted HDL used for MatX designs.
Production-proven experience with silicon microarchitecture and design concepts used in high-performance compute (such as CPUs, GPUs, or accelerators), high-speed connectivity, memory management, and related functionality.
Experience with SystemVerilog, Python, C/C++, and similar scripting and programming languages used for chip design and related flows.
Experience testing designs and working closely with verification teams toward performance and coverage closure goals.
Hands-on experience with design synthesis, design lint, and related flows for high-quality sign-off.

Nice To Haves

Prior experience with Bluespec or familiarity with functional-programming paradigms such as Haskell.
Experience designing ML arithmetic and compute datapaths, including matmul or systolic (MAC) arrays, reduction trees, and floating-point or special-function units such as MuFu.
Familiarity with verification and emulation platforms and methodologies.
Extensive experience with logic focused on moving, storing, or managing data, such as caches, buffers, and crossbars.

Responsibilities

Contribute to MatX’s silicon architecture-to-design methodology with scalable solutions across blocks, subsystems, and full-chip design.
Own entire subsystems or subsets and/or chip-level silicon design deliverables from microarchitecture through sign-off-ready design.
Plan and drive intermediate and sign-off reviews of microarchitecture and design specifications, execution progress, and area and timing closure toward milestones including design freeze and tapeout.
Work closely with verification, DFT, and physical-design co-owners of the relevant subsystem or block to deliver best-in-class performance, power, and area results.
Test designs and work with verification teams toward performance and coverage closure goals.
Use design synthesis, design lint, and related flows to take designs to high-quality sign-off.

Benefits

Four weeks of accrued PTO, 12 company holidays, and up to three weeks of remote work.
Company-subsidized medical insurance for employees and dependents; dental and vision insurance for employees and dependents; employee life insurance; and HSA and FSA offerings.
Roth and/or pre-tax 401(k) with a 5% company contribution, long-term disability insurance, and travel insurance.
$1,500 annual professional development budget.
Onsite team lunch and dinner Monday through Friday.
Daily commute coverage, including company rideshare, public-transit reimbursement, and/or a Fasttrak card.
$50 per month for a selected employee perk.
Monthly cellular reimbursement of $35 and Wi-Fi reimbursement of $40.
Up to $1,000 for remote office setup purchases through the company Amazon account.
Company-paid mental health benefit and Guardian EAP.
Up to 12 weeks of paid parental leave, 10 weeks of pregnancy disability leave, flexible return-to-work hours, and a $6,000 Family Fund for eligible family-related needs.
100% company-paid life insurance up to $300,000.
