Description

Fervo Energy is building the most cost-effective, repeatable geothermal power plants in the world. Achieving this mission requires disciplined financial operations, strong controls, audit-ready documentation, and scalable processes that support Fervo’s transition into a public-company operating environment. Joining Fervo means operating at the intersection of energy infrastructure, growth-stage execution, and public-company readiness, where reliability, accountability, and continuous improvement are foundational.

We are seeking an Assistant Controller to lead and strengthen Fervo’s general ledger, monthly close, cash and bank reconciliation, prepaids, accruals, intercompany, allocations, consolidations, and account reconciliation processes. This is a senior leadership role within the Controller organization, accountable for a close and reporting function that is accurate, efficient, well documented, and ready for public-company controls.

The Assistant Controller will report to the Controller and own core close, general ledger, and reporting activities across multiple entities, serving as the Controller’s deputy on close and controls matters.

Fervo is scaling rapidly, so this role requires strong ownership, crisp communication, a controls mindset, and the ability to partner effectively across Accounting, Finance, Operations, Legal, Tax, Treasury, Commercial, and external advisors.
