Architect, Medium Voltage (MV) Electronic Hardware

• 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.

WHO YOU ARE AND WHAT YOU BRING

• Bachelor’s in Electrical Engineering (Power Electronics, Power Systems, or related). Master’s or Ph.D. preferred.
• 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.
