Developer Augmentation Engineer

What MatX Is Building

MatX runs frontier AI models. We push ML workload efficiency to the physical limit, in order to bring AGI years earlier vs counterfactual. We are developing a vertically-integrated solution, from silicon to software, to train and run the largest ML workloads in existence. We are looking for people who are excited about our mission and will enjoy learning to do what we do.

What You Will Do Here: meta-level work

Augment our architects

Take their toil upon yourself

Apply theory-of-mind and legwork to conserve architect time

Annihilate the toil with tooling and AI agents

Earn knowledge across the stack and trust across the team

Do object-level work: getting your hands wet helps you do meta-work even better

Transform the way we work by incorporating AI into our workflows

Become a generalist: use the knowledge and trust you learned to solve problems across the company

Object-level things you'll be working on & learn how to do:

Our hardware architecture: spec, diagrams, rationale

Rust simulator for our architecture

RTL code of our behemoth-scale AI Acceleration ASIC

Design Verification of this ASIC

Infrastructure to enable all of the above

Future-oriented research:

High-level Python simulations for architectural features

ML experiments for validating our approach to AI

Writing RL environments to improve frontier-llm performance on hardware design tasks

Who You Are

0 - 2 years of experience with systems programming using Rust / Python / HDLs. Linux experience is a must. Non-coursework projects preferred; among HDLs, RTL experience preferred

You are a strong communicator, with the ability to flex to various styles (since you'll communicate with everyone in the company)

You have a "Get Things Done" mentality. You roll up your sleeves to proactively problem-solve, undeterred by challenges and limitations. The words "that's not my job" are blasphemy!

You are genuinely interested in people and see the support of others as enabling people's best work for the success of the company

You are able to context switch, shifting between tactical and big-picture. You can zoom through multiple levels of abstraction with ease, tracking cross-scope implications

You believe that kindness matters. You have a strong regard for the dignity and lived experience of others. You can spot situations at work where kindness and respect may be lacking, and bring it back to basics

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. We will support your relocation

Bonus Points If You Have

Experience optimizing hardware or software

ML experience, especially with LLMs

Infrastructure experience: Google Cloud Platform and Github

Experience with CLI coding agents: incl. Codex / Claude Code / Gemini CLI
