Enphase Energy is a global energy technology company and a leading provider of solar, battery, and electric vehicle charging products. Founded in 2006, our innovative microinverter technology revolutionized solar power, making it a safer, more reliable, and scalable energy source. Today, the Enphase Energy System enables users to make, use, save, and sell their own power. Enphase is also one of the most successful and innovative clean energy companies in the world, with more than 80 million products shipped across 160 countries.   Join our dynamic teams designing and developing next-gen energy technologies and help drive a sustainable future!About the Role The Enphase Energy SST Product Innovation Team sits in the Office of the CTO and is responsible for defining, prototyping, and scaling the next generation of Enphase power systems. We are a fast-moving, multi-disciplinary group pushing the boundaries of medium-voltage power conversion, energy density, and grid-scale deployment. Solid-state transformers (SSTs) are a fundamentally new product category. The standards landscape is fragmented, evolving, and often ambiguous — spanning power electronics, transformer, switchgear, and grid interconnection domains simultaneously. We need a Compliance Lead who does not just read standards and check boxes, but who understands why each clause exists, can track its technical origin, and can navigate the gray areas where multiple standards intersect or where no standard clearly applies. This role is for someone who thrives in ambiguity. You will lead Enphase through the full compliance lifecycle for novel medium-voltage SST products — from identifying applicable standards during early architecture, to planning and executing certification testing with NRTLs and international agencies, to negotiating interpretations with Authorities Having Jurisdiction (AHJs). If you are energized by tracking down the technical rationale behind every requirement and turning that knowledge into a competitive advantage, this role was built for you. What You Will Do <ul><li style="font-family:sans-serif , arial , helvetica;font-size:10.0pt;">Own the SST compliance strategy end-to-end: Define the compliance roadmap for Enphase SST products from concept through certification and market launch. Identify all applicable safety, performance, and grid interconnection standards. Map the certification pathway and timeline for each product variant and target market  </li><li style="font-family:sans-serif , arial , helvetica;font-size:10.0pt;">Track down the 'why' behind every standard: Go beyond surface-level compliance. Understand the technical rationale, test intent, and engineering origin of each standard clause. Use this deep understanding to guide design decisions, identify the most efficient path to compliance, and defend Enphase's technical position when interpretations are contested. </li><li style="font-family:sans-serif , arial , helvetica;font-size:10.0pt;">Navigate ambiguity in evolving standards: SSTs sit at the intersection of power electronics (UL 1741, IEC 62109), medium-voltage equipment (UL 347A, IEC 62477-2), transformers (UL 1562, IEC 60076), switchgear (IEEE C37 series, IEC 62271), and grid interconnection (IEEE 1547, IEEE 2800). Many of these standards were not written with SSTs in mind. Identify gaps, overlaps, and conflicts between standards and develop a defensible compliance strategy for each. </li><li style="font-family:sans-serif , arial , helvetica;font-size:10.0pt;">Lead certification testing with NRTLs and agencies: Plan, coordinate, and lead certification test campaigns with Nationally Recognized Testing Laboratories (UL, Intertek/ETL, CSA, TUV). Own the relationship with test engineers and project managers at the labs. Prepare test plans, manage sample submission, witness testing, and resolve findings. Drive toward certification on schedule. </li><li style="font-family:sans-serif , arial , helvetica;font-size:10.0pt;">Integrate compliance into the design process: Embed compliance requirements into product architecture from day one. Participate in design reviews and provide early feedback on insulation coordination, creepage/clearance, dielectric withstand, partial discharge limits, grounding, arc-flash protection, EMC, and functional safety. Prevent late-stage surprises by front-loading standards analysis. </li><li style="font-family:sans-serif , arial , helvetica;font-size:10.0pt;">Build and maintain the compliance knowledge base: Create and maintain a living library of applicable standards, technical interpretations, agency decisions, and test results. Document the rationale behind every compliance decision so the team can reference it across product generations and personnel changes. </li><li style="font-family:sans-serif , arial , helvetica;font-size:10.0pt;">Drive pre-compliance and internal validation testing: Work with the engineering team to define and execute internal pre-compliance testing (dielectric withstand, impulse, temperature rise, EMC, partial discharge) before formal agency submission. Identify and close gaps early to minimize certification risk. </li><li style="font-family:sans-serif , arial , helvetica;font-size:10.0pt;">Sit on OCP, IEEE, and UL committees to drive industry evolution: Represent Enphase on standards development committees and industry working groups — including the Open Compute Project (OCP) for data center power standards, IEEE committees (IEEE 1547, IEEE 2800, IEEE C37) for grid interconnection and protection, and UL Standards Technical Panels (UL 1741, UL 347A) for safety certification. Actively shape evolving compliance and regulation in Enphase's favor by driving technical contributions, proposing requirements aligned with SST technology, and building industry relationships that give Enphase early visibility into upcoming standards changes. </li></ul>Who You Are and What You Bring <ul><li style="font-family:sans-serif , arial , helvetica;font-size:10.0pt;">BS, MS, or PhD in Electrical Engineering, Mechanical Engineering, or closely related field </li><li style="font-family:sans-serif , arial , helvetica;font-size:10.0pt;">Job title and level determined by candidate experience: </li><li style="font-family:sans-serif , arial , helvetica;font-size:10.0pt;">Principal Engineer: BS + 15 yrs | MS + 12 yrs | PhD + 8 yrs </li><li style="font-family:sans-serif , arial , helvetica;font-size:10.0pt;">Candidates with greater experience are strongly encouraged to apply </li><li style="font-family:sans-serif , arial , helvetica;font-size:10.0pt;">Ability to track down the technical 'why' behind standards — required: Must demonstrate the ability to read a standard clause and understand its engineering origin — what failure mode it prevents, what test condition it simulates, and what assumptions underlie it. This skill is essential for navigating ambiguous or conflicting requirements and for defending Enphase's technical position with agencies and AHJs. </li><li style="font-family:sans-serif , arial , helvetica;font-size:10.0pt;">Proven ability to deal with ambiguity — required: SSTs are a new product category that does not fit neatly into any single existing standard. Must be comfortable operating where standards are incomplete, contradictory, or silent. Able to develop a defensible compliance strategy from first principles when the rulebook does not have a clear answer. </li><li style="font-family:sans-serif , arial , helvetica;font-size:10.0pt;">Experience leading certification testing with NRTLs — required: Hands-on experience planning and executing certification test campaigns with nationally recognized testing laboratories (UL, Intertek/ETL, CSA, TUV).
