Senior Power Electronic Engineer

Our client, LiquidPiston, is seeking a Senior Power Electronics Engineer to expand their Electrical Engineering team. Due to the nature of their work, only U.S. citizens, Green Card holders, or H-1B visa holders will be considered for this role.

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

• BS or MS in Electrical Engineering or related field
• 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.
