Lead Principal Engineer
$178,200 - $245,100 USD yearly
Explore resonant converters, GaN, SiC, and HV-IBC architectures for high-density AI datacenter power delivery.
Originally posted August 10, 2026 by the employer.
About the role
This role leads the conceptualization, design, and validation of power electronics subsystems tailored for high-density AI accelerators, telecom, and server power supplies. Focus areas include custom DC-DC power converters, resonant converters, wide-bandgap semiconductors such as GaN and SiC, and HV-IBC architectures.
What you'll do
- Execute the system solution roadmap for AI datacenter and telecom solutions, including application notes, solution boards, block diagrams, and simulation models.
- Lead the design and validation of power electronics subsystems, focusing on custom DC-DC power converters capable of sustaining transient power demands in AI training and inference.
- Explore DC/DC power conversion topologies, including resonant converters, HV-IBC architectures, and wide-bandgap semiconductors (GaN, SiC).
- Perform market research, system teardowns, and architecture evaluations for telecom and server power supplies to identify topologies and technical issues.
- Support customer RFIs/RFQs and provide technical input for digital and analog controllers and power stage product feature definitions.
- Mentor engineers, deliver technical trainings, and conduct design reviews before board-level releases.
What you'll need
- M.S. in Electrical Engineering with at least 12 years of experience, or B.S. in Electrical Engineering with at least 15 years of experience in power electronics with an emphasis on isolated and non-isolated DC/DC power converters.
- Extensive knowledge of DC-DC converter topologies, magnetic components, and power semiconductor characteristics.
- Experience developing DC/DC power converter solutions including concept, block diagrams, simulation, schematic, PCB layout, board-level debugging, test, and validation.
- Experience using simulation and PCB design tools.
- Experience mentoring junior engineers, providing power electronics training, and conducting design reviews.
Nice to have
- Experience using digital and analog controllers and gate drivers for power management (Si and GaN).
- Experience in magnetics design and optimization.
- Experience with safety and EMI compliance.
- An advanced degree or doctorate in electrical engineering, power electronics, or a related technical field.
- Expertise in telecom brick designs, rack power supplies, and Artificial Intelligence power delivery.
- At least 5 years of relevant work experience in Application Engineering or System Engineering, ideally at an OEM, Tier 1, or Engineering Service Provider.

How we counted: 64 open Power Electronics (Power Conversion) roles from 22 employers tracked in the SemiconductorJobs index, counted 14 Nov 2026. Specialty figures count only roles carrying this exact specialty label, so an employer's related work in neighbouring specialties is not included there, and is counted in the wider Analog & Mixed-Signal family row. Days are counted from when our index first saw each posting, not from the employer's original posting date.
