Senior Power Electronics Engineer
Originally posted 2 February 2026 by the employer.
About the role
This role involves the end-to-end design, development, and validation of isolated power conversion products. The focus includes isolated DC-DC power converters (200V-10kV working voltage) and power systems within a 100W to 10kW range for telecom, AI, ATE, and satellite applications.
What you'll do
- Architect, design, and develop isolated DC-DC power converters and power systems.
- Design and specify custom transformers and inductors, optimizing for performance, cost, and manufacturability.
- Ensure designs comply with international safety requirements (e.g., UL/IEC/EN 60950-1, 62368-1).
- Interface with and program onboard microprocessors and system managers for power supply control, monitoring, and communication (e.g., PMBus, I2C).
- Design for Electromagnetic Compatibility (EMC), developing strategies to mitigate EMI and conducted noise to meet CISPR/FCC Class A and B standards.
- Lead the technical execution of projects, including schematic capture, PCB layout supervision, prototyping, and validation testing.
What you'll need
- B.S. in Electrical Engineering or a related field.
- 7+ years of experience in the design and development of isolated switch-mode power supplies (SMPS).
- Proven expertise in transformer design for high-frequency power conversion, including core selection, winding techniques, and isolation barrier design.
- In-depth understanding of galvanic and capacitive isolation standards, design practices, and validation methods.
- Strong knowledge of microprocessor/microcontroller integration for power control, including programming and debugging skills (C/C++).
- Demonstrable experience designing to meet safety and EMC requirements for Telecom, AI, ATE, and/or Satellite applications.
- Proficiency in simulating, modeling, and mitigating EMI and conducted noise.
- Hands-on experience with power supply prototyping, module and PCB assembly, soldering, and debugging.
- Understand all DC/DC architectures and topologies: ex. Buck-boost, flyback, current mode, COT.
- Familiarity with current sharing techniques and N+1 redundant power architectures.
- Experience with power levels ranging from 100W to 10kW.
- Proficiency with schematic capture and PCB layout tools (e.g., Altium Designer, Cadence).
- Experience with power electronics simulation tools (e.g., PSIM, Simplis).
Nice to have
- Experience with wide-bandgap semiconductors (GaN, SiC).
- Knowledge of thermal management and mechanical packaging for high-density power supplies.
- Experience with high-voltage design (> 1kV).
- Familiarity with reliability prediction models (e.g., MIL-HDBK-217, Telcordia).
