Power Electronics Engineer

About the role

Harbinger is an American commercial electric vehicle (EV) company on a mission to transform an industry starving for innovation. Harbinger's best-in-class team of EV, battery, and drivetrain experts have pooled their deep experience to bring a first-of-its-kind EV platform to support the growing demand for medium-duty EVs and Hybrids.

Responsibilities

• Architect and Lead: Drive the architecture, component selection, analysis, and design of high-power (100kW to MW class) power electronics aimed at high performance and cost optimization, including on-board chargers, DC-DC converters, and traction inverters.
• End-to-End Testing: Lead the testing and bring-up of power electronics components, seamlessly integrating them with powertrain components and the broader charging ecosystem.
• Advanced PCB Design: Oversee and execute the design of complex circuit boards (PCBs), optimizing for low-cost, high-reliability, and high-performance based on IPC standards.
• Reliability & Analysis: Lead DFMEA, worst-case circuit analysis (WCCA), thermal analysis, and other critical system-level evaluations.
• Validation Leadership: Direct testing and validation efforts on high voltage components and systems, setting the standard for test protocols within the team.
• Hands-on Bring-Up: Architect test bench setups and provide hands-on support for board-level, component-level, and vehicle-level bring-up at in-house facilities and external test sites.
• Cross-Functional Troubleshooting: Collaborate with and mentor cross-functional teams to troubleshoot, diagnose, and resolve complex electrical and EMI issues as they arise.
• Strategic Sourcing: Engage strategically with suppliers and the sourcing team to identify, evaluate, and procure cutting-edge components. Support design releases and modifications based on vendor capabilities.
• Technical Communication: Generate comprehensive technical reports and present critical design reviews to executive leadership and key stakeholders.

Requirements

• High-Power Experience: You have a proven track record of designing, building, and testing high-power electronics projects. Experience in the 100s of kW range is required, with Megawatt (MW) scale experience being highly desirable.
• Industry Flexible: You have 10+ years of hands-on electrical engineering experience. We are open to backgrounds in automotive, robotics, aerospace, grid-scale energy storage, marine, rail, or renewables—as long as you have worked at these demanding power levels (100kW+).
• Deep Technical Expertise: Strong, authoritative background in analog/digital electronics, power conversion, and energy storage technology (including power electronics, control theory, motor drives, and battery systems).
• Design & Test Master: You are equally comfortable at a CAD workstation as you are in the high-voltage lab. You possess strong hands-on capabilities for testing and troubleshooting complex electrical components and systems.
• Education: Strong academic background (BS/MS/PhD) in Electrical Engineering, Applied Physics, or closely related fields with a focus on high voltage systems.
• Mixed Signal & Tools: Extensive experience with the electrical design of mixed-signal PCBs for traction inverters or on-board chargers. Highly proficient with Altium Designer (or similar schematic/layout tools) and circuit simulation software like LTspice.
• EMI/EMC Expert: Proven experience troubleshooting and resolving complex EMI/EMC related issues.
• System Integration: Familiarity with software, digital communication specifications, and embedded firmware development is a strong plus.
• Mechanical Familiarity: Experience with CATIA to support design releases is a strong plus.
• Leadership: Exceptional problem-solving skills with the ability to effectively communicate, mentor junior engineers, and collaborate dynamically within a fast-paced team environment.
