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

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

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.

• $120,000 - $400,000 + equity
