Senior Power Electronics Engineer – Hardware Design

The Senior Power Electronics Engineer will lead the design and development of advanced DC-DC power conversion products, including PDNs, point-of-load modules, and high-efficiency buck and resonant topologies for data center, AI, telecom, and computing applications. This role owns the full hardware design cycle—from concept and simulation through validation and high-volume production—while collaborating with global R&D teams across firmware, magnetics, thermal, and manufacturing. The engineer will drive innovation in high-density, high-reliability power architectures, support existing platforms, mentor junior engineers, and help position OmniOn Power at the forefront of next-generation power delivery solutions.

This role will report to the R&D Technology Manager and will be located at our HQ in Plano, TX

Job Description
We are seeking a Senior Power Electronics Engineer to lead the design and development of cutting-edge DC-DC power conversion products for high-performance computing, AI power delivery, telecom, and enterprise applications. In this role, you will drive new hardware designs from concept through high-volume production, focusing on point-of-load (POL) converters, power delivery networks (PDNs), and high-efficiency buck and resonant topologies. You will work closely with global R&D, firmware, magnetics, thermal, and manufacturing engineering teams to deliver high-density, high-reliability power solutions while supporting continuous improvement of existing platforms.

Key Responsibilities

• Lead the design of isolated and non-isolated DC-DC converters, including buck, resonant, and multiphase topologies.
• Define and optimize PDN and POL architectures for transient response, noise, thermal performance, and power density.
• Use simulation tools such as PSPICE, SIMPLIS, SIMetrix, or Ansys for modeling, design optimization, and validation.
• Develop schematics, bills of materials, and guide high-density PCB layouts for performance and manufacturability.
• Perform lab-based validation, debugging, characterization, and compliance testing of prototypes.
• Collaborate with firmware, magnetics, mechanical, and manufacturing teams to ensure robust design and smooth production launch.
• Support existing product families through component alternates, quality improvements, and lifecycle management.
• Mentor junior engineers, lead design reviews, and contribute to innovation and intellectual property generation.

Basic Qualifications

• B.S. in Electrical Engineering or related field (M.S. preferred).
• Minimum 7 years of experience in power electronics hardware design.

Preferred Skills

• Experience with GaN or SiC device-based designs.
• Knowledge of magnetics and thermal design for high-density converters.
• Familiarity with digital control loops, compensation, and mixed-signal power stages.
• Understanding of EMI/EMC mitigation techniques and compliance test requirements.
• Strong analytical, communication, and teamwork skills.
• Proven experience with POL converters, PDNs, buck converters, and resonant or soft-switching topologies.
• Hands-on lab expertise in testing, validation, and failure analysis of power converters.
• Proficiency with schematic capture, PCB design, and circuit simulation tools.
