Technology Leader - Power Electronics

About the role

Mainstream Engineering is seeking a Technology Leader – Power Electronics to lead the development of next-generation power conversion technologies for demanding commercial, industrial, and defense applications. This role requires an experienced engineer who can solve complex challenges, mentor engineers, and bring cutting-edge technologies from concept to production.

Responsibilities

• Lead the architecture, design, development, and testing of high-performance AC-DC, DC-DC, and DC-AC power converters ranging from 1 kW to 150+ kW.
• Drive the development of advanced motor drive systems operating from 10,000 RPM to over 150,000 RPM.
• Develop and implement sophisticated digital control algorithms, digital filtering techniques, and closed-loop control strategies for power electronic systems.
• Lead the design and testing of power stages, gate drivers, and sensor electronics utilizing state-of-the-art Silicon Carbide (SiC) and Gallium Nitride (GaN) semiconductor technologies.
• Design, evaluate, and integrate high-power SiC and GaN power modules for advanced energy conversion applications.
• Oversee the design, layout, fabrication, and validation of analog and mixed-signal printed circuit boards.
• Develop embedded control systems using DSPs, microcontrollers, and FPGA-based architectures.
• Guide projects through the complete product lifecycle, from concept development and prototyping through testing, qualification, and production.
• Provide technical mentorship to engineers across multidisciplinary teams.
• Collaborate closely with mechanical, thermal, manufacturing, and systems engineers to develop innovative solutions for complex engineering challenges.
• Support business development activities by contributing technical expertise to proposal efforts and customer engagements.

Requirements

• Bachelor's degree in Electrical Engineering from an accredited university with a minimum GPA of 3.3.
• Minimum of 5 years of hands-on experience designing and developing power electronic systems.
• Demonstrated experience designing, testing, and troubleshooting power conversion equipment at or above 100 kW.
• Strong background in variable frequency drives (VFDs) and motor control systems.
• Experience with power electronics design, simulation, laboratory testing, and system integration.
• Strong understanding of analog and digital circuit design principles.
• U.S. Citizenship is required due to U.S. Government ITAR program restrictions.

Preferred Qualifications

• Master's or Ph.D. in Electrical Engineering or a related field.
• Experience working with wide-bandgap semiconductor technologies including SiC and GaN devices.
• Experience programming microcontrollers, DSPs, and FPGA-based control systems.
• Familiarity with MATLAB/Simulink, PLECS, LTspice, or similar modeling and simulation tools.
• Experience leading technical teams, mentoring engineers, or serving as a subject matter expert.
• Experience developing products for aerospace, defense, energy, or advanced industrial applications.
