About Endurance

Endurance is building the world's first modular subsea geothermal power plants, converting vast thermal resources under the ocean into gigawatts of baseload power. Backed by Founders Fund, Felicis, First Round Capital, and Point
72 Ventures, our founding team includes veterans from SpaceX, Helion, Blue Origin, and Apple. We have completed multiple deep-ocean deployments to subsea volcanoes and are launching a long-term demonstration project this fall. By leveraging modular design, manufacturing scale, efficient drilling, and latent cooling on the seafloor, we are pioneering a new category of energy that outperforms traditional sources on environmental impact, deployment speed, and cost.

The Controller owns the books at Endurance and builds the machinery that maintains them. You will stand up the accounting function from scratch: the monthly close, GAAP financials, internal controls, ERP, and the multi-entity structure behind our projects. Your mandate is to make Endurance audit-ready from day one and keep it that way as we grow from startup into an owner-operator of power plants around the world.

We are scaling a factory, standing up project entities, and heading into institutional diligence, and none of it works without accounting infrastructure that holds up: a fast and reliable close, clean consolidation across entities, cost accounting that reflects real production, and controls that pass audit. The decisions you make on systems and entity structure this year are ones the company will live with for a decade.

You will report directly to the COO, transitioning to finance leadership as the team grows. You will work directly with executives, auditors, and outside counsel, design the function to run without heroics, and hire the accounting team as the company scales.

• Build and lead the accounting team as the company grows, and stand up the systems and processes the function runs on.

• ~10 years of progressive accounting experience, including controller or assistant controller ownership at a scaling company. We care about what you have built, not where you sat; backgrounds in venture-backed hardware startups, energy or industrial companies, project finance companies, or public accounting followed by industry can all…
