Senior Accountant

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 Senior Accountant, you’ll build and run the accounting function behind a company that manufactures and deploys infrastructure. You’ll be one of the first members of our finance team. You’ll report to our CFO and work across operations, procurement, manufacturing and construction. You will:

• Close the books: Own the monthly close, including reconciliations, accruals, journal entries and financial statements, accurately and on a schedule the team can count on.

• Own payables: Process vendor invoices and payments, and keep vendor records, W-9s and 1099s in order as procurement ramps.

• Manage expense reports: Review and process employee expense reports, reconcile card spend to receipts, and make sure spend follows our expense policy.

• Run cost accounting: Track material, labor and overhead costs across manufacturing and construction projects, so we know what each Terrain build costs and that it is capitalized correctly.

• Count and reconcile inventory: Run inventory counts, reconcile counts to the books, and track components from receipt through installation.

• Build the accounting process: Partner with the accounting team to establish Mavria’s processes, workflows and approvals, and document them as you build them.

• Automate the routine: Use software and AI tools to cut manual entry and shorten the close.

We’re looking for an experienced, hands-on accountant with the following qualities:

• Accurate: Your numbers tie out, and you catch errors before anyone else sees them.

• Grounded in GAAP: You know accrual accounting and US GAAP, and you know when to research or ask how a new type of transaction should be recorded.

• A builder: You’re comfortable setting up processes from scratch, not only running processes someone else built.

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

• Tech-forward: You learn new software quickly, are strong in Excel, and use AI tools to automate repetitive work.

Experience in manufacturing, construction or project accounting, or at a fast-growing company, is especially relevant. A CPA, or progress toward one, is a plus but not required. We value ability over years or titles.

To apply: Share your background and an example of an accounting process you built or improved.

• 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
