Office Manager & Executive Assistant

Mavria’s mission is to build the industrial capacity America needs to lead in AI. We believe that sustaining America’s AI leadership requires an unprecedented expansion of power, manufacturing, supply chains and physical infrastructure.

Our founders are serial entrepreneurs who met at the U.S. Department of Energy, working on some of the country’s hardest energy and infrastructure projects. There, they saw a widening gap: AI labs and cloud providers were racing to scale compute, while the infrastructure underneath them was still built one custom project at a time, on timelines measured in years.

We founded Mavria to close that gap. We are building to industrialize intelligence: turning the physical infrastructure AI runs on into products we manufacture, deploy and improve with every build.

We’re starting with data centers. Our first product, Terrain, is a factory-built data center platform. Terrain 01 is being built in Houston now, and we’ve raised $130M as of October 2026 to accelerate our roadmap.

Terrain is our first product, not the limit of our ambition. We intend to eliminate the physical bottlenecks that constrain American AI leadership and build one of the foundational infrastructure companies of the AI era.

At Mavria, three principles guide how we work:

• Ambition: We want to build a generational company. To do that, we build capabilities, not just products. Terrain is our first product, not our last – and we seek to eliminate strategic bottlenecks across the entire AI supply chain.

• Urgency: AI moves in weeks, while infrastructure tends to move in years. We match the frontier’s pace by making decisions quickly, building in parallel and securing critical supply ahead of demand. We surface problems early and never compromise on safety or engineering rigor.

• Ownership: When we say we’ll do something, we do it. Keeping our word is how we stand apart, and taking radical ownership over our scope and our domain is how we build trust – internally and externally – while moving fast.

As our office manager and executive assistant, you’ll keep our Houston office running and give our leadership team more hours in the day. This is more than a front-desk role: you’ll own projects end to end, manage our offices as the team grows in headcount and scope, and become the office lead our Houston team relies on to get things done. You will:

• Run the Houston office: Manage office vendors, supplies, the facility and everything else that keeps our largest office working, so the team can focus on building.

• Support our executives: Manage calendars, travel, expenses, meetings and correspondence for members of the leadership team, and anticipate what they need before they ask.

• Own projects: Take on company initiatives and special assignments, track them to completion, and close the loop with the people who depend on them.

• Automate the routine: Use software and AI tools to take recurring work off your plate and off everyone else’s.

• Shape the culture: Plan team events and the day-to-day rituals that make the office a place people want to be.

We’re looking for an experienced office manager or executive assistant who wants a bigger scope, with these qualities:

• Organized: You keep track of many requests at once and nothing falls through the cracks.

• Discreet: You’ve supported senior executives and handled confidential information with care.

• An owner: You take a task from request to done without being chased, and you flag problems early.

• A great first impression: You’re warm and professional with everyone who walks in or calls.

• Tech-forward: You pick up new software quickly, are experienced with AI tools, and look for ways to automate repetitive work.

Experience opening or moving an office, planning events, or supporting a fast-growing company is especially relevant. We value ability over years or titles.

To apply: Share your background and an example of a project or office you ran from start to finish.

• Competitive total compensation package

• Medical, dental, and vision insurance is 100% paid for the employee

• Retirement Plan with a 3.5% company match

• Flexible time off
