ON.energy is building the power infrastructure that makes the AI era possible. As AI demand surges past what the grid and traditional data centers can support, ON.energy provides a new class of power technology proven at gigawatt scale and trusted by the world’s leading cloud and AI companies. Our systems are already deployed across 2.5 GW of hyper-scale campuses, validated by top U.S. national labs, and certified for grid-safe operation by major utilities. With real products in the field, we’re scaling faster than the grid can, transforming power from a bottleneck into a competitive advantage for the companies building the future.
The Role
We are far from the traditional corporate mold. At our core, we are a high-speed team built on deep trust, mutual support, and an unwavering commitment to excellence. Here, ownership is a mindset, not an assignment. We sweat the details, run toward change, and over-prepare so we can execute at the highest level. We take our work seriously because it’s vital to the future of technology, but we don’t take ourselves too seriously. If you are ready to own your impact, work safely, and win championships with a talented, supportive group of people, this is where you belong.
As Audit Manager, you will build ON.energy's internal audit function from the ground up — establishing the audit charter, methodology, and reporting cadence, and setting the multi-year, risk-based audit roadmap the function will run on. You will own our SOX compliance program end to end, from pre-SOX readiness (scoping, risk-and-control matrices, narratives, and control design) through post-SOX execution (annual testing, deficiency evaluation, and remediation). This role calls for someone who has audited from the outside and built or scaled an audit function from within, and who is ready to set the standard for how ON.energy audits itself.
Key Responsibilities
- Build and lead ON.energy's internal audit function from the ground up, including drafting the audit charter, operating model, and reporting structure to senior leadership.
- Develop and own a multi-year, risk-based internal audit roadmap covering operational, financial, compliance, and IT/cyber risk areas, and refresh it annually against an enterprise risk assessment.
- Support and stand up the company's pre-SOX readiness program: scope in-scope processes and entities build risk-and-control matrices (RCMs) and process narratives, and identify control gaps ahead of formal SOX applicability.
- Plan and lead complex, risk-based operational and financial audits from planning through fieldwork, workpaper review, and final reporting.
- Serve as the liaison with external auditors on internal controls reliance, SOX walkthroughs, and coordination of testing scope to reduce duplication of effort.
- Present audit results, control deficiencies, and remediation status to senior management and, as needed, the Audit Committee and Board.
- Build the function's audit toolkit: workpaper templates, sampling methodology, audit management/tracking software, and data analytics approaches to standardize how audits are run.
- Hire, train, and mentor internal audit staff as the function scales, and build the team structure and succession plan to support ON.energy's growth.
- Partner with Legal, Compliance, FP&A, and business unit leaders to align on control ownership, policy design, and enterprise risk priorities.
- Track audit findings and control deficiencies to closure, including follow-up testing to confirm remediation is operating as designed.
- Monitor changes in relevant regulatory and professional standards (SEC, PCAOB, COSO, IIA Standards) and update the audit methodology and SOX program accordingly.
