• Develop and document system-level functional specifications, requirements, and integration plans across electrical, software, and mechanical domains.
• Develop and execute system and subsystem/converter test plans to validate functionality, performance, reliability, thermal, EMC, and safety compliance testing, and analyze test data for compliance and performance.
• Collaborate with team members and compliance and certification experts to ensure adherence to UL, IEEE, CSA, and EMC standards.
• Support or perform the selection, design, and validation of key power components (magnetics, semiconductor devices, gate drivers, circuit protection, and sensors).
• Develop requirements for, source, and validate custom or semi-custom components, typically inductors or transformers, for power electronics systems, employing electromagnetic and/or thermal modeling tools, analysis, and hand calculations.
• Apply modeling and simulation tools to predict performance, optimize efficiency, and validate design decisions.
• Lead integration of subsystems into complete systems.
• Work hands-on in lab environments to debug and characterize hardware and system interactions, ensuring safe conditions in high-voltage high-power environments.
• Support field validation testing and customer evaluations of new products.
• Collaborate closely with software, firmware, and mechanical engineers to ensure cohesive system design and manufacturability.
• Mentor and provide technical leadership to more junior engineers
• Participate in continuous improvement efforts, driving quality, reliability, and efficiency across product lines.

• Bachelor’s degree (BSEE) required; Master’s degree (MSEE) preferred, with a focus in power electronics, electrical engineering, or a related field.
• 10+ years of experience in electrical engineering projects in the field of power electronics and/or power systems.
• Knowledge of buck/boost, multi-phase/interleaved, DAB, LLC, and H-bridge topologies, and working experience with some of these topologies.
• High-voltage (>400V AC or DC) and high-power (>10kVA) applications, including safety isolation, gate drives, current sensors, magnetic components, and isolated communications.
• Experience with communications protocols such as ethernet, CAN, I2C and RS-232. 
• Product development experience for complex power electronics systems, i.e., containing multiple power converters and circuit boards, and embedded control software.
• Experience developing systems with multiple embedded MCU, DSP, FPGA or CPU devices.
• Experience with grid-connected systems.
• Hands-on experience performing system- and subsystem-level validation testing, including thermal, EMI/EMC, and performance verification.
• Knowledge of UL, IEEE, CSA, and EMC compliance standards and validation testing methods.
• Proficiency with electrical modeling and simulation tools
• Familiarity with Design for Manufacturability (DFM), Design for Test (DFT), and reliability engineering practices.
• Experience working on team projects including collaboration with software and mechanical engineering functions.
• Strong leadership skills, with the ability to guide and mentor junior engineers. 
• Excellent problem-solving abilities, capable of addressing complex technical challenges independently. 
• Effective communication and interpersonal skills, with the ability to collaborate with cross-functional teams and manage stakeholders. 
• Highly organized, with the ability to manage multiple complex projects and priorities. 
• Experience conducting failure analysis and implementing corrective actions for design-related issues.
