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, 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 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. WHAT YOU'LL DO - Review and sign off on the monthly close prepared by our outsourced accounting firm, covering journal entries, accruals, prepaids, fixed assets, payroll entries, intercompany activity, and cash and balance sheet reconciliations. - Own the chart of accounts, accounting policies, and the internal reporting package. - Run a monthly reconciliation routine: every balance sheet account reconciled, preparer separate from reviewer, exceptions cleared. - Prepare Endurance for audits, investor and lender diligence, and board reporting. Own the control environment, the PBC list, and organized records for all external stakeholders. - Keep payroll, benefits, and equity accounting right: multi-state payroll in Gusto, benefits deductions reconciled from carrier invoice to payroll to GL, stock comp tied to the cap table. - Serve as the primary internal owner of the outsourced accounting relationship, and coordinate with tax advisors on income, franchise, and sales/use tax, and R&D credit documentation. - Initiate time-sensitive wires under dual control, own vendor onboarding (W-9s, payment setup, banking-detail verification, approval routing), and keep clean records on major vendor contracts and project spend. - Work with the Head of Finance on technical accounting positions: SAFEs and preferred stock, stock comp, leases, and R&D and project cost capitalization. - Help lead the NetSuite migration: chart-of-accounts and entity design, data migration, and redesigning close, AP, and reporting workflows. REQUIRED SKILLS AND EXPERIENCE - 6+ years of accounting experience, ideally a mix of public accounting and operating-company roles. - You've owned a monthly close with sign-off responsibility. - Audit experience on either side: company-side through a financial statement audit, or as an external auditor. - Strong US GAAP foundation. - Experience managing or reviewing outsourced accounting, bookkeepers, or tax advisors. - Comfort in the details: wires, vendor setup, coding, and documentation. - Ability to work independently and build processes from scratch in a fast-paced, ambiguous startup. PREFERRED SKILLS AND EXPERIENCE - CPA. - NetSuite or ERP implementation experience. - Multi-entity or multi-currency consolidation. - Startup, hardware, energy, infrastructure, or other project-based company experience. - Experience with QuickBooks Online, Bill.com http://Bill.com, Brex, Gusto, and Carta. COMPENSATION, BENEFITS, & PERKS As a pre-revenue startup, Endurance Energy offers competitive base salaries and generous equity packages for full-time employees. Final base salary will be determined by an array of factors including internal equity, job-related knowledge, skills, and work experience. A key aspect of our compensation philosophy is that value creation should be aligned with rewards. Right now this means equity is a significant portion of every full-time employee's compensation. As the company matures, there will be continued evolution and changes to the total rewards and total compensation package. What will always be true is that if we win, we win together. Equity is granted to every full-time employee as a meaningful piece of ownership. We believe the people building the company should share directly in the value they create. In addition to a competitive base salary and equity, employees will receive all of our other great benefits and perks, including: - Benefits: Health, Dental, and Vision insurance coverage - Time Away: Flexible PTO including 12 paid company holidays - Global Fieldwork: Travel to fascinating deployment sites along oceanic ridges in locations like the Pacific Northwest, Hawaii, Iceland, Japan, New Zealand, and the Azores - Hands-on Experience: Participate in sea trials and deployment operations in partnership with leading oceanographic institutions - Cutting-edge Development: Work with technology that spans high-power electronics, marine systems, and clean energy - Impactful Work: Help solve one of the world's most pressing challenges - Dive Certification: Company-sponsored recreational dive certification - Other Perks: Access to the company boat, free meals and snacks, and the list goes on!
