Job description

About Stone Power

The US needs 1.5 terawatts of new power by 2035. AI has scaled beyond our ability to build power, and the existing power supply chain is the bottleneck. You cannot buy a new gas turbine until 2030: order books at GE, Siemens, and Mitsubishi stretch past 2030. Turbine prices have nearly tripled since 2019. The future demands a new kind of hardware company, building a new kind of turbine. That's Stone.

We are America's Turbine Company, designing, fabricating, and deploying turbines for a $200B+ market that's tripling by the early 2030s. We are building our own factories. We are delivering our own natural gas, steam, and advanced turbines. And we are doing it with an AI stack built specifically for hardware.

Natural gas turbines are the first leaf on a multi-decade tech tree. The same physics kernel, the same factory, and the same team will deliver natural gas turbines, nuclear turbines, geothermal turbines, and heat recovery systems. Natural gas is how we get going. Nuclear (on and off planet) is how we become a generational company.

We are seeking our first Controller to join our team on-site in Los Angeles. This is a key founding-team leadership role responsible for owning the close process, audit readiness, and internal accounting controls as we scale our manufacturing operations. You will establish our manufacturing cost accounting framework, manage the 2026 year-end close, and build the financial infrastructure necessary to support upcoming audit and S-1 IPO compliance.

Key Responsibilities

• Financial Close & Controls: Fully own the month-end and year-end close processes, beginning with the 2026 financial close, and establish internal accounting controls.

• Manufacturing Cost Accounting: Build and maintain hands-on cost accounting systems for turbine production, covering inventory management, standard costing, job costing, and variance analysis.

• Audit & IPO Readiness: Lead external audit preparations and establish financial reporting processes aligned with S-1 IPO compliance standards.

• Grant & Financial Compliance: Manage financial tracking and compliance requirements for grants and specialized funding programs.

Qualifications & Requirements

• Certification: Certified Public Accountant (CPA) is required.

• Experience: 5+ years of progressive accounting experience with dedicated, hands-on experience in manufacturing cost accounting.

• Technical Skills: Proven expertise in inventory control, standard costing, job costing, and variance analysis.

• Work Location: Ability to work full-time on-site in Los Angeles, CA.

Preferred Qualifications

• Experience managing grant compliance frameworks.

• Background starting in Big Four audit practice followed by hands‑on industry experience at a hardware or manufacturing company.
