Principal Electrical Engineer - Power Electronics

Key Responsibilities

• Lead power electronics design for low-to-mid power systems in the 0.5 kW to 5.0 kW range
• Define architecture and requirements for power conversion solutions connected to small generators and internal test platforms
• Design and develop high-power PCBA solutions (schematics + layout; Altium preferred)
• Design, integrate, and validate converter topologies (buck/boost, isolated and non-isolated DC-DC, inverter/rectifier stages as applicable)
• Own magnetics-related design decisions: inductor/transformer selection or design, core and copper loss considerations, thermal tradeoffs
• Select, characterize, and validate power semiconductor devices (MOSFET, IGBT, SiC, GaN, BJT as applicable), including gate drive considerations and switching loss tradeoffs
• Develop practical protection and reliability approaches (EMI/EMC basics, inrush, transient protection, fault handling, thermal protection)
• Integrate power electronics with MCU/DSP controllers: sensing, feedback loops at a system level, interfaces, and bring-up support (firmware collaboration expected; not a pure firmware role)
• Build, assemble, and bring up prototypes in the lab; debug issues quickly and methodically
• Plan and execute validation testing using oscilloscopes, power analyzers, supplies, loads, thermal tools, and instrumentation
• Drive design-for-manufacturing: vendor engagement, fab/assembly coordination, component sourcing risk, test strategy, and production readiness
• Design for real-world environmental conditions: enclosure integration, thermal management, IP-rated constraints, potting/encapsulation considerations
• Evaluate third-party or consultant designs for simplicity, robustness, safety margin, and manufacturability
• Help maintain and improve the electrical lab environment: tooling, organization, safety, and practical process improvements

Required Qualifications

• Bachelor’s degree in Electrical Engineering or closely related field (Master’s preferred but not required)
• 8+ years of hands-on power electronics experience (Principal level typically 12+)
• Demonstrated experience designing PCB-based power electronics in the 0.5 kW to 5.0 kW power range
• Strong understanding of magnetics, core and resistive losses, and thermal management in power designs
• Experience selecting and testing power semiconductor devices (MOSFET, IGBT, SiC, GaN, etc.)
• Familiarity with multiple power converter architectures and how they integrate with MCU/DSP-based control systems
• Experience designing for environmental constraints (IP-rated enclosures, sealing, encapsulation/potting, vibration/handling considerations)
• Proven track record bringing power electronics to market: requirements - design - validation - manufacturing handoff
• Strong technical judgment, ability to troubleshoot in the lab, and comfort making tradeoffs under real constraints
• Able to work independently while collaborating tightly with a small engineering team
