Responsibilities
Define end-to-end architecture for MV electronic hardware systems: topology, component selection, insulation coordination, creepage/clearance, dielectric barriers, thermal management, EMI/EMC strategy, and safety
Architect grid-tied MV power conversion solutions including front-end rectifiers/inverters, MV transformers, relaying/protection, auxiliary power systems, and controls
Translate customer, utility, and regulatory requirements into system and subsystem specifications; own the Requirements, DVP&R, and Safety Case
Lead and participate in hands-on design: schematics, electrical circuit design, MV busbar structures, partial discharge mitigation, surge protection, grounding/bonding, and HV PCB layout practices
Guide FEA/thermal/electromagnetic analyses; review models and prototypes; oversee DFMEA/PFMEA, reliability prediction (MTBF/Weibull), HALT/HASS, and failure analysis
Establish design standards, templates, and best practices for MV equipment; coach engineers and review critical design artifacts
Engage directly with customers, EPCs, and utilities to capture use cases, grid codes, protection schemes, and site constraints; lead technical workshops and design reviews
Advise product from concept to launch: technology downselect, make/buy, supplier selection, design verification/validation, certification testing, manufacturability, and cost-out
Collaborate with Compliance to plan and execute certification and type tests (e.g., dielectric, impulse, short-circuit, temperature rise, EMC)
Ensure designs meet relevant standards and codes (examples below) and internal safety policies
Identify and help shape evolving standards consistent with customer and Enphase needs
Advise development of documentation: architecture descriptions, interface control documents (ICDs), protection & coordination studies, commissioning procedures, and user manuals
Qualification
Required
Bachelor's in Electrical Engineering (Power Electronics, Power Systems, or related)
10+ years of hands-on design experience with MV equipment (1 kV–35 kV): MV power converters, switchgear, transformers, relaying/protection, or MV distribution equipment
Proven experience architecting grid-scale power electronics or MV systems (e.g., utility-scale BESS PCS, MV motor drives, HV rectifiers, FACTS, HVDC/HV traction)
Deep knowledge of insulation coordination, partial discharge, creepage/clearance, surge withstand, corona mitigation, and dielectric testing
Strong background in power devices, snubbers, commutation loops, and low-inductance bus structures
Proficiency with EMI/EMC design and compliance (conducted/radiated emissions, immunity, filtering, shielding, bonding)
Experience with protection & relaying, coordination studies, and MV switchgear integration (ANSI/IEC)
Demonstrated leadership in cross-functional product development and successful product launch
Excellent communication skills for customer interface, technical presentations, and executive updates
Preferred
Experience with utility interconnection and grid codes (e.g., IEEE 1547, UL 1741 for PCS; country-specific equivalents)
Knowledge of MV standards and practices: ANSI/IEEE: C37 series (switchgear & breakers), IEEE 1584 (arc flash), IEEE C62 (surge arresters), IEEE 242/399 (protection/coordination), IEEE 519 (harmonics)
IEC: 62271 (HV switchgear/controlgear), 60664 (insulation coordination), 60060 (HV test techniques), 61000 series (EMC), 61800-5-1 (drives safety), 60076 (power transformers)
UL/CSA/NEMA: UL 347 (MV industrial control equipment), UL 508C/IEC 61800 for drives, UL 1741/CSA equivalents for grid-tied PCS, NEMA ratings
NFPA: 70 (NEC), 70E (electrical safety)
Experience in MV PCS integration, MV switchgear, pad-mount transformers, protective relays, SCADA, and utility interconnects
Familiarity with reliability engineering (DVP&R, DFMEA/PFMEA, HALT/HASS), design controls (ISO 9001), and safety lifecycle (functional safety, SIL concepts, if applicable)
Tools: Power electronics simulation (PLECS/PSIM/Matlab/Simulink), electromagnetic/thermal FEA, PCB CAD, relay coordination tools (ETAP/SKMs), and scripting for data analysis
Experience with manufacturing for MV hardware: buswork, encapsulation/potting, cast resin, partial discharge test setups, and high-voltage lab procedures
Track record of supplier development (transformers, busbars, capacitors, relays, breakers, arresters) and design-to-cost
