Join us
We build the world's best chips and racks for training and serving large language models. Our work spans the entire range from silicon and rack design, through compilers and kernels, to ML models.
We believe, more than any other AI chip company, that low precision compute performance is the most important aspect of chip design.
Consider new approaches
We're solving a different problem than previous products, so our solutions will often be different. We readily abandon traditional approaches when there's a better path in our context.
Understand deeply
We carefully reason through consequences of big decisions. A few days of thinking can be worth more than weeks of simulation. This is how we make big bets with high confidence.
Invite and include
We're a high-trust team who supports each other. We take contributions seriously and make sure good ideas are heard, even when they mean major shifts in direction.
Ship quality work
Whether in hardware, software, or ML, we value readable, resource-efficient code and solutions to real technical problems. We're interested in all experience levels.
Everyone on the MatX team is exceptional. Our new grads have strong training and learn quickly. Our veterans have built ML chips, compilers, and models across the industry. Several of us have built a chip with 30 people where other companies might take 300.

A real person reads every resume. We consider your whole background—side projects, past successes, different perspectives—not just credentials. Depending on what's required for the role, this process may differ.
Application
You'll get a confirmation when you apply. We can only send personal responses to candidates we're moving forward with.
Technical interview
If there's a good fit, we schedule a call to share more about the role and dig into your technical background.
Behavioral interview
For some roles, we add a conversation about team dynamics, leadership, and communication.
Team interviews
A series of interviews with peers and leaders, usually back-to-back in one session. If scheduling doesn't allow that, we'll spread them within 24 hours so things keep moving.
Onsite visit
We try to bring candidates to our office to meet the team, see the space, join us for lunch, and chat with the founders. If you can't make it in person, we'll set up a final video call instead.

We are hiring across software, compiler, machine learning, silicon and hardware systems engineering roles. We work in person three days a week in our office in Mountain View, California.
Do you sponsor green cards?
Once you're eligible, we're happy to support and start the process.
Do you sponsor visas?
Visa sponsorship is available for some roles. While we can't guarantee sponsorship for every position, we're open to discussing options and will make a good-faith effort to support candidates to whom we extend offers.
Can I get feedback on my application?
Due to application volume, we're unable to provide individual feedback on resumes or interviews.
Can I re-apply if I'm not selected?
We appreciate your enthusiasm for MatX. If things don't align this time, we encourage you to reapply after six months.
Do you have a formal internship program?
No. In rare circumstances we do consider interns for certain roles.
