Staff Power Electronics Hardware Design Engineer

Quick Facts

• Own the power-stage hardware design for power conversion products
• Senior individual contributor leading a hardware workstream
• Designs high-voltage, high-power rectifiers, inverters, and DC/DC converters

Description

Own the power-stage hardware design for assigned power conversion products, setting the hardware design rules used by the product line. You will design power stages, gate drives, protection/fault-detection circuits, and supporting circuits for high-voltage rectifiers, inverters, and DC/DC converters. You will lead hardware activities through validated prototypes and release to commercial-scale manufacturing, while mentoring other hardware engineers.

Responsibilities

• Own the power-stage hardware design and define product-line hardware design rules
• Design AC/DC, DC/AC, and bidirectional/interleaved DC/DC converters using Si and SiC devices (e.g., MOSFETs, IGBTs, SCRs)
• Design gate drives; current/voltage sensing; protection and fault-detection; auxiliary power supplies
• Design supporting circuits: DC links, pre-charge/discharge, input/output filters, snubbers/clamps, relay/contactor drives, fan control/monitoring, and interfaces to capacitor/supercapacitor energy storage
• Specify and qualify low- and high-frequency magnetic and filter components
• Analyze losses, thermal performance, component stress and derating; collaborate on cooling, busbars, and packaging
• Design for safety/compliance (insulation coordination, creepage/clearance, EMC/EMI) against standards such as UL 62477-1
• Define hardware requirements for controls/firmware and review designs for hardware compatibility
• Produce schematics and design intent for PCB designers; review layouts for high-power fast-switching circuits
• Perform paper-based design verification; lead design validation via prototype build/testing; specify validation, production, and regulatory compliance test methods
• Write specifications, calculations, design-review packages, and released documentation in PLM
• Lead hardware design reviews; plan and track scope/schedule for the hardware workstream
• Support transfer to production and resolve hardware issues in production and field
• Mentor engineers

Requirements

• Bachelor’s degree in electrical engineering (or related technical field)
• 10+ years of power electronics hardware design experience
• Experience taking high-power AC/DC, DC/AC, or DC/DC power stages from schematic to validated prototypes using Si and SiC power devices
• Gate drive design and power semiconductor selection experience
• Extensive analog design experience for power/instrumentation systems (sensing, communications, fault monitoring/protection)
• Experience with magnetic/filter component design and EMC/EMI compliance approaches
• Experience applying insulation coordination, creepage, and clearance for high-voltage equipment
• Experience defining hardware requirements for modulation/control software and programmable logic
• Ability to perform paper-based design verification and specify prototype build/test/validation and production/regulatory compliance test methods
• Experience working with PCB designers and mechanical engineers on floorplans, packaging, interfaces, and cooling
• Schematic capture, simulation, and modeling skills with LTspice, MATLAB, Simulink, PSIM, and Python; document control and PLM experience
• Hands-on laboratory experience with high-voltage, high-power hardware
• Technical leadership, documentation skills, and mentoring ability

Benefits

• Travel within North America up to 20%
• Onsite role preferred (Merrimack, NH; Pointe-Claire, QC considered)
