Key Responsibilities

  • Design, simulate, prototype, debug, and improve power electronics hardware for advanced engine and generator systems
  • Develop and support converters, inverters, motor drives, power distribution systems, battery interfaces, and related hardware
  • Perform hands-on hardware bring-up, troubleshooting, validation, rework, and root-cause analysis of electrical and thermal failures
  • Address real-world hardware challenges including EMI/EMC issues, component failures, manufacturability concerns, and reliability improvements
  • Work closely with electrical, mechanical, embedded controls, and test engineers to develop fully integrated products
  • Oversee external vendors and contractors, including reviewing designs, identifying issues, and resolving integration or quality problems
  • Execute rapid prototype development, bench testing, and in-house troubleshooting to support development timelines
  • Contribute to related electrical engineering efforts beyond core PE, including engine controls, genset controls, instrumentation, wiring, and general EE tasks
  • Support iterative product development and continuous improvement activities throughout the product lifecycle
  • Operate effectively in a fast-paced small-company environment where priorities may shift and engineers are expected to take broad ownership

Required Qualifications

  • Strong hands-on experience designing and developing power electronics hardware
  • Experience with converters, inverters, motor drives, high-current/high-voltage systems, or related power electronics applications
  • Practical experience with hardware debugging, lab testing, prototype integration, and failure analysis
  • Strong understanding of real-world electrical engineering tradeoffs including thermal management, PCB layout, EMI/EMC, reliability, and manufacturability
  • Experience working with external vendors, contract manufacturers, or third-party design firms
  • Comfortable performing hands-on lab work including soldering, rework, instrumentation, and troubleshooting
  • Ability to work across disciplines and contribute to broader electrical and system-level engineering challenges
  • Adaptable, self-motivated, and comfortable working in a highly collaborative small-team environment
  • Strong problem-solving skills and a demonstrated ability to drive hardware issues to resolution quickly and effectively
  • Passion for building and improving real-world hardware products

Preferred Qualifications

  • Experience with weight- and efficiency-critical designs (e.g., aerospace, defense, UAVs).
  • Background in hybrid power systems, gensets, and MIL-STD compliant systems (e.g., AMMPS).
  • Knowledge of CANBUS/MODBUS communication protocols.
  • Hands-on experience with PCB layout and design tools such as Altium or OrCAD.
  • Firmware development experience (C/C++ preferred).
  • Project management skills with experience coordinating across teams and with external stakeholders.
