Microarchitect and RTL Designer - Compute
Confirmed on the employer's own hiring board on Oct 21, 2026. First seen by Alion on Oct 19, 2026. MatX scores B on the Alion truth index.
What MatX is Building
MatX's mission is to make the world’s best AI models run as efficiently as allowed by physics, bringing the world years ahead in AI quality and availability.
What Compute Means
The compute subsystem implements all of the core numerics and the associated control and data paths required to realize meaningful hardware acceleration of our target ML workloads. In this role you own the micro-architecture and RTL for blocks within it, end to end.
What You'll Do Here:
Contribute to MatX's silicon architecture-to-design methodology with a scalable solution across blocks, subsystems, and fullchip design
Own entire subsystems or subsets and/or chip-level silicon design deliverables from micro-architecture to sign-off-ready design
Plan and drive intermediate and sign-off reviews on micro-architecture and design specifications, execution progress, and area and timing closure toward various silicon milestones including design freeze and tapeout
Work closely with the verification, DFT, and physical design co-owners of the subsystem/block in question and deliver best-in-class performance-power-area results
Who You Are:
At least 5 years of silicon design experience
Tape-out experience - you have taped out chips, demonstrating end-to-end ownership of a design through multiple generations
Ability and willingness to ramp on Bluespec - a functionally-rooted HDL used for our designs. Prior Bluespec, or familiarity with functional-programming paradigms (e.g. Haskell), is a plus
Production-proven experience with silicon micro-architecture and design concepts used in high-performance compute (CPUs, GPUs, accelerators), high-speed connectivity, memory management, and related functionalities
Experience with SystemVerilog, Python, C/C++, and similar scripting and programming languages for chip design and related flows
Experience testing your designs and working closely with verification teams toward performance and coverage closure goals
Hands-on experience with design synthesis, design lint, and related flows to take designs to high-quality sign-off
Bonus Points If You Have:
Experience designing arithmetic/compute datapaths for ML - matmul / systolic (MAC) arrays, reduction trees, and floating-point / special-function units (e.g. MuFu)
Familiarity with verification, emulation platforms, and methodologies
A lot of experience with logic that focuses on moving, storing, or managing data such as caches, buffers, crossbars, etc.
