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.
We’re looking for a Principal Compliance Engineer with deep expertise in regulatory requirements, codes, and certification processes applicable to BESS, power electronics, and electrical distribution systems e.g. panelboards, switchboards, etc.. This is a product-focused and cross-functional role responsible for ensuring that our systems meet all applicable North American and international standards, as well as ISO/RTO interconnection and market requirements. You will serve as the internal authority on compliance, working closely with product, R&D, and project engineering teams to ensure designs are certifiable, deployable, and aligned with evolving regulatory frameworks.
Key Responsibilities:
- Lead compliance strategy and execution for BESS, DC cabinets, inverters, and related power, controls /IT equipments.
- Interpret and apply standards such as UL, CSA, IEEE, IEC, and NFPA to product and project designs.
- Act as the subject matter expert on ISO/RTO regulatory requirements (e.g., interconnection, grid codes, testing protocols).
- Define and manage certification roadmaps for new and existing products.
- Coordinate and support product testing and certification activities, including UL listings, field evaluations, and special inspections.
- Develop and maintain with Technical Writer compliance documentation, including test plans, reports, and certification packages.
- Work directly with NRTLs and certification bodies to facilitate approvals and resolve technical issues.
- Support engineering teams by ensuring designs meet code and standard requirements from early development stages.
- Review and validate test procedures and results, including electrical, thermal, environmental, and safety testing.
- Support project teams during AHJ reviews, permitting, and commissioning, addressing compliance-related questions.
- Monitor and interpret regulatory changes and emerging standards, ensuring proactive alignment of products.
Required Skills & Experience:
- Bachelor’s degree in Electrical Engineering, Mechanical Engineering, or related field.
- 10+ years of experience in compliance, certification, or regulatory engineering for BESS, power electronics, or industrial electrical systems.

- UL (e.g., UL 9540, UL 9540A, UL 1741, UL 508A)
- CSA standards for electrical equipment
- IEEE standards related to power systems and interconnection
- IEC standards for international compliance
- NFPA (e.g., NFPA 855)
- Deep understanding of test procedures and certification processes, including safety, thermal runaway, environmental, and performance testing.
- Familiarity with ISO/RTO requirements (e.g., ERCOT, PJM, CAISO, MISO) and grid interconnection standards.
- Experience working with NRTLs (e.g., UL, CSA, Intertek) and managing certification programs.
- Ability to interpret and apply codes, standards, and regulatory language into practical engineering requirements.
- Strong communication skills across engineering, regulatory authorities, and external certification bodies.
- Project Management skills.
Preferred Experience:
- Experience with utility-scale and/or C&I BESS deployments.
