Power Electronics Engineer

Job Title: Power Electronics Engineer

Job Description

This role offers the opportunity to design and develop next-generation power electronics hardware for applications such as solar energy, energy storage, EV charging, and test systems. You will take designs from concept through productization, working with advanced technologies including Silicon Carbide (SiC) and Gallium Nitride (GaN) MOSFETs, and will play a key role in creating high-frequency, high-density power conversion solutions that meet rigorous performance, safety, and compliance standards.

Responsibilities

• Design and develop next-generation power electronics hardware for solar, energy storage, EV charging, and test applications using SiC and GaN MOSFET technologies.
• Develop high-frequency bidirectional DC-DC converters, AC-DC grid-tie inverters, and resonant converter topologies.
• Lead the full product development lifecycle from initial concept and architecture through detailed design, prototyping, testing, and productization.
• Create and implement innovative digital control algorithms for power converters and control systems.
• Design and optimize magnetic components, including high-frequency inductors and transformers, to meet performance, efficiency, and thermal requirements.
• Collaborate closely with PCB layout designers to realize high-density, high-voltage power designs that meet EMI/EMC and thermal constraints.
• Work closely with mechanical designers to integrate power hardware into complete products, including sheet metal, heat sinks, bus bars, and other mechanical structures.
• Achieve UL and CE compliance for power electronic products by incorporating safety, isolation, and protection requirements into the design.
• Lead EMC compliance activities, including filter design, test planning, debugging, and design improvements to meet regulatory requirements.
• Apply strong understanding of high-frequency power stages, filtering, circuit protection, thermal management, and EMI/EMC considerations throughout the design.
• Use tools such as MATLAB, Simulink, and Simscape/SimPower Systems to model, simulate, and optimize power converter performance and control.
• Support and follow the product development process, including design reviews, documentation, validation testing, and transfer to manufacturing.
• Demonstrate an intense focus on customer satisfaction by understanding application requirements and resolving technical issues promptly and effectively.
• Assist team members in achieving project-level budgets and schedules on assigned projects.
• Foster open communication and effective collaboration among engineering, sales, operations, quality, and other business functions.
• Participate in a culture of continuous learning, driving standardization, design quality, and manufacturability improvements across products.
• Ensure compliance with all applicable safety and work rules and help maintain high housekeeping and organizational standards in the work area.
• Communicate and coordinate with multiple vendors and cross-functional teams to source components, resolve technical issues, and support project milestones.
• Contribute to root-cause analysis and continuous improvement using structured problem-solving tools and methodologies.

Essential Skills

• Bachelor’s degree in Electrical Engineering.
• Minimum 2 years of related experience in power electronics and control systems design.
• Strong experience in power electronics design, including converter topologies and control.
• Solid understanding of basic physics and electronics fundamentals.
• Strong understanding of high-frequency power stages, filtering, circuit protection, thermal management, and EMI/EMC considerations.
• Hands-on experience with MATLAB, Simulink, and SimPower Systems (or similar simulation tools) for modeling and analysis.
• Demonstrated experience with the product development process, from concept through validation and release.
• Experience with hardware design and PCB design for power electronics applications.
• Knowledge of EMI/EMC principles and practical considerations in power hardware design.

Additional Skills & Qualifications

• Master’s degree in power electronics or a closely related field.
• More than 5 years of industry experience in power converter development as a new product development (NPD) or R&D engineer.
• At least 5 years of experience in the design, testing, and debugging of DC-DC or three-phase AC-DC converters in the 400–900 V range and power levels above 2 kW.
• Experience in the selection and design-in of power semiconductor devices, cooling mechanisms, passive components, protection circuits, and sensing circuits.
• Understanding of PCB layout techniques for high-voltage and high-density power electronics.
• Familiarity with UL1741 and typical safety and EMI standards for power converter systems.
• Familiarity with EMC requirements and filter design for compliance.
• Understanding of hardware–mechanical interfaces, including integration with enclosures, thermal management, and interconnects.
• Understanding of hardware–software interfaces, including how control firmware interacts with power hardware.
• Knowledge of fundamental analytical equations and design methods for high-frequency inductors and transformers.
• Experience communicating and coordinating with multiple vendors and distributed teams.
• Experience operating in a power-electronics-focused development environment.
