• Proficiency with MATLAB, Simulink, and SimPower Systems for modeling and analysis.
• Hands-on experience with hardware design and power electronics circuits.
• Experience with PCB design concepts and collaboration with PCB layout engineers.
• Familiarity with EMI/EMC principles and practical mitigation techniques.
• Experience with structured product development processes and taking designs from concept to production.
• Excellent oral, written, and listening communication skills, with the ability to collaborate effectively with internal and external stakeholders.
• Strong organizational skills with the ability to manage multiple tasks and priorities.
• Ability to work independently, take ownership of tasks, and consistently meet deadlines.
• Strong process orientation and discipline, including demonstrated use of problem-solving tools such as root cause analysis, 5-Why Analysis, 8D, or Six Sigma.
• Demonstrated commitment to customer service, teamwork, and cross-functional collaboration.

Responsibilities

• Design and develop next-generation power electronics for solar, energy storage, electric vehicle charging, and test applications using Silicon Carbide (SiC) and Gallium Nitride (GaN) MOSFETs.
• Develop high-frequency bidirectional DC-DC converters, AC-DC grid-tie inverters, and resonant converters for medium- to high-power applications.
• Lead the full product development lifecycle from concept, architecture, and design through prototyping, validation, and productization.
• Create and implement innovative digital control algorithms for power converter systems.
• Design and develop advanced magnetics, including high-frequency inductors and transformers.
• Collaborate closely with PCB layout designers to implement high-density, high-voltage power designs with careful consideration of EMI/EMC and thermal performance.
• Work closely with mechanical designers to develop complete product designs, including sheet metal, heat sinks, bus bars, and related mechanical interfaces.
• Achieve UL and CE compliance for power electronic products by defining requirements, supporting testing, and implementing design improvements.
• Lead EMC compliance activities, including planning, testing, troubleshooting, and mitigation of EMI issues.
• Use simulation tools such as MATLAB, Simulink, and SimPower Systems to model, analyze, and optimize power converter topologies and control strategies.
• Support the design and selection of power semiconductor devices, cooling mechanisms, passive components, protection circuits, and sensing circuits.
• Ensure designs incorporate appropriate filtering, circuit protection, thermal management, and EMI/EMC considerations.
• Contribute to and follow a structured product development process, including design reviews, documentation, and verification and validation activities.
• Demonstrate a strong focus on customer satisfaction by understanding application requirements and delivering reliable, high-quality solutions.
• Assist team members in meeting project budgets and schedules, and contribute to effective project planning and execution.
• Foster open communication and collaboration across technical and business functions, including sales, operations, and quality.
• Participate actively in an environment of continuous learning, driving standardization and high-quality design practices with a focus on manufacturability.
• Apply structured problem-solving tools such as root cause analysis, 5-Why, 8D, or Six Sigma methodologies to resolve technical issues.
• Ensure compliance with all safety and work rules and maintain high standards of housekeeping within the engineering and lab environments.
