Join our dynamic teams designing and developing next-gen energy technologies and help drive a sustainable future!
 
We are seeking a Architect for Medium Voltage (MV) rated electronic hardware (typically 1 kV to 35 kV) to lead the architecture and development of next-generation power conversion equipment for grid-scale applications. This leader will combine deep, hands-on engineering experience with system-level architecture to define product roadmaps, drive end-to-end designs, engage with customers and utilities, and guide teams through innovation, development, validation, certification, and successful launch.
You’ll advise the technical direction for MV equipment including power conversion (e.g., MV inverters/PCS), transformers, protection & control, insulation systems, and interface requirements for utility interconnection. You will collaborate cross-functionally with Product, Manufacturing, Quality, Supply Chain, and Field Service to deliver robust, cost-effective, and certifiable products.
WHAT YOU WILL DO
Architecture & System Design 
  • 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.
Hands-on Engineering & Technical Leadership 
  • 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.
Customer & Utility Interface 
  • Engage directly with customers, EPCs, and utilities to capture use cases, grid codes, protection schemes, and site constraints; lead technical workshops and design reviews.
Program Leadership & Cross-Functional Execution 
  • 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).
Standards, Safety & Compliance 
  • 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.

PREFERRED QUALIFICATIONS

  • 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.
KEY COMPETENCIES
  • Systems Thinking & Tradeoffs — Balances performance, safety, reliability, cost, manufacturability, and compliance.
  • Technical Leadership — Mentors engineers; sets standards; makes decisive architecture choices.
  • Customer Orientation — Translates real-world operating conditions and grid constraints into robust designs.
  • Execution Excellence — Drives schedule, risks, and quality; owns outcomes of assigned tasks.
  • Communication — Clear written/verbal communication, crisp design reviews, and executive-ready.
  • Ownership & Integrity — Champions safety and compliance; leads by example.
