Sr Accounting Manager (Controller Track)

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 Point72 Ventures, our founding team includes veterans from SpaceX, Helion, and Robinhood. We have completed multiple deep-ocean deployments 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 both environmental impact and cost.

THE ROLE

Endurance is hiring a Senior Accounting Manager, on a defined Controller track, to own our general ledger and force audit readiness. Our outsourced accounting firm does the day-to-day bookkeeping and prepares the close, and will continue to. Your job is to own the output: review their work and build internal processes to prepare the accounting function for scaled operations.

About 15–20% of the role is hands-on: initiating urgent wires, setting up vendors, and stepping into AP or bookkeeping work when speed matters.

A major near-term priority is our migration from QuickBooks Online to NetSuite. You'll play a central role in that transition (chart-of-accounts design, data migration, process redesign), and you'll help stand up consolidation for our first international subsidiary.

This role will report to the Chief Executive Officer.

PATH TO CONTROLLER

Promotion criteria will be based on close cadence with the outsourced firm, balance sheet reconciliations, audit readiness, and NetSuite implementation. Formal review at 12 months, promotion targeted by 18, with a compensation step and equity refresh. From there, you build the internal accounting team under you.
