What MatX Is Building

MatX is building cutting-edge AI infrastructure at the intersection of hardware and software, on a mission to make the world's best AI models run as efficiently as possible. We're growing fast, and our CEO's time is one of the most valuable resources in the company. This role exists to protect and multiply it.

About This Role The Office of the CEO at MatX operates as a team of three: the CEO, his Chief of Staff, and you (reporting to the Chief of Staff). You’ll own the operational surface area of this office, allowing the CoS and CEO to focus on company-wide strategy and operational decision-making. You’ll turn calendaring, communications, and logistics into a multiplier for the CEO’s impact on company outcomes.

You'll learn how we work: how the CEO thinks and prioritizes, how the CoS works, and where the gaps are. You'll start filling those gaps on your own: drafting follow-up emails, figuring out next steps and who owns them during meetings, or proactively suggesting comms to address the themes you’re hearing across the company.

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

What You’ll Do Here

• Calendar and time management. You own the CEO's schedule and use it to strategically spend his time. You'll learn company priorities, when he needs buffers, which "quick calls" are actually high-priority, and when to protect personal time
• Communications and follow-through. You'll handle and prioritize incoming emails, take notes and send action items to other team members, and work with the CEO to figure out what type of follow-up works best. Over time, you'll draft routine communications on behalf of the CEO and the CoS (meeting recaps, stakeholder updates, scheduling coordination)
• Meeting support. You'll prepare agendas, coordinate logistics, and own the follow-up. If action items come out of a meeting, you're the one tracking them and making sure they actually get done
• Operational support for company initiatives. This team owns large cross-functional projects — reorganizations, process overhauls, etc. You'll support execution: tracking deliverables, coordinating across teams, flagging when something's slipping, and keeping the machinery running once the strategy is set
• Personal logistics. Occasionally you'll book a dinner reservation, coordinate a personal appointment, or handle something that doesn't fit neatly into a work category.
• Confidential information. Discretion is a baseline requirement. You’ll be in the room for sensitive conversations and have access to personal information. We take this very seriously

Who You Are

• You have a bias toward action. You're comfortable being wrong and treat mistakes as a learning experience. We'd much rather course-correct someone who acts than try to inject initiative into someone who waits
• You're a fast pattern-matcher and an active listener. You understand quickly. You pick up on preferences, rhythms, and unspoken priorities quickly by thoughtfully listening to what people mean, rather than just what they say
• You're low-ego. You take genuine pride in the operational work that makes everything else possible. You’re very curious, like learning about things outside of your area of expertise, and are happy to say, “I don’t know,” when you’re asked a question. You can handle blunt feedback without taking it personally
• You like working on a team. You proactively look for ways to help your team members. You understand that an increase in clear communication allows for an increase in speed. You like accomplishing tasks as a group
• You like taking things from chaos to calm. A perfectly organized calendar, a meeting where the right pre-read arrived at the right time, a microphone in-hand at exactly the right time during the Town Hall, calling out action items from a week ago that everyone else forgot about
• Bachelor's degree equivalent or 1–3 years of professional experience. Time spent in a startup-like environment at a tech company or similar. The specific title you held matters less than how you operated.
• Strong critical thinking to quickly synthesize information and challenge assumptions.
• Comfort with ambiguity. We're not going to hand you a playbook. You'll need to build your own
• Ability to influence cross-functional stakeholders and drive outcomes without direct authority
• Based in or willing to relocate to the Bay Area
