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.
