Principal Compliance Engineer

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.

Responsibilities

• 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.
• Track down the 'why' behind every standard: 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.
• Navigate ambiguity in evolving standards: Identify gaps, overlaps, and conflicts between standards and develop a defensible compliance strategy for each.
• 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
