Senior Power Electronics Engineer

Job Description

Insight Global is seeking a Senior Power Electronics Engineer for a client developing advanced high-power energy infrastructure. This role will be responsible for the design, simulation, prototyping, validation, and commercial release of high-power, grid-connected converters for applications including utility-scale energy storage, data centers, and industrial electrification. The position requires technical breadth across semiconductor switching physics, circuit-level dynamics, high-voltage magnetics, converter controls, and multi-megawatt system architectures. This engineer will work cross-functionally with firmware/software, mechanical, thermal, manufacturing, compliance, certification, reliability, and NPI teams to transition complex power electronics designs into robust, production-ready hardware. Key Responsibilities • Architect and implement advanced bidirectional, isolated, and non-isolated converter topologies, including DAB, resonant, multilevel, MMC, and multi-stage SST architectures. • Partner with mechanical and manufacturing engineering to integrate high-power converter modules and stacks with thermal management, racking, structural support, and system-level enclosures. • Develop layouts that minimize circuit parasitics, including loop inductance and gate-loop parasitics, while managing voltage overshoot, ringing, and electromagnetic interference. • Design custom high-frequency magnetic components, balancing core losses, skin/proximity copper losses, and thermal dissipation. • Partner with embedded controls and firmware engineers on digital control implementation. • Lead hands-on hardware bring-up, testing, debugging, and iterative design revisions, validating electrical and thermal performance against theoretical models. • Apply DFM, DFA, DFT, and Design for Cost principles throughout the hardware development lifecycle to support scalable manufacturing. • Collaborate with NPI and manufacturing engineering to establish production assembly flows, end-of-line functional testing, and second-source strategies for critical components.

Skills and Requirements

• MS or PhD with a specialization in power electronics. • 5+ years of relevant industry experience with an MS, or 3+ years with a PhD, developing high-power, high-voltage converters from kW through multi-MW scale. • Experience taking complex high-power electronics hardware from concept through prototyping, certification, and handoff to sustained high-volume production. • Experience taking high-power, grid-tied converter designs from topology selection and modeling through physical commercial product development. • Expertise in Design for Excellence (DFX), including identifying manufacturing bottlenecks, reducing COGS, and improving production yield. • Deep understanding of power semiconductor switching physics, device capacitance dynamics, wide-bandgap semiconductors, safe operating area, and thermal constraints. • Experience identifying and mitigating high-frequency parasitics and noise coupling in multilayer PCBs, busbars, and power modules. • Familiarity with power converter control, digital signal processing, and grid-following and grid-forming inverter control methodologies. • Hands-on experience in high-power, high-voltage laboratory environments using oscilloscopes, differential probes, Rogowski coils, network analyzers, and power analyzers. • Proficiency with circuit simulation, schematic capture, and thermal/magnetic modeling tools such as PLECS, SPICE/LTspice, and Simulink. • Familiarity with PLM/CAD environments used to manage BOMs, ECOs, and production handoffs. • Experience with medium-voltage converters and systems, including insulation coordination, clearance/creepage design, and partial-discharge mitigation. • Experience with utility-scale grid-connected systems, including switchgear, circuit breakers, and protective relays. • Familiarity with industrial hardware packaging, structural busbars, encapsulation/potting, conformal coating, and liquid-cooling architectures. • Familiarity with applicable UL, IEEE, and IEC standards and grid codes.
