About LiquidPiston
LiquidPiston is revolutionizing combustion engine technology through the development of advanced rotary engines and integrated hybrid power systems. Our innovative designs aim to dramatically improve efficiency, reduce size and weight, and enable cleaner, more compact power solutions across defense, aerospace, and commercial sectors.
Position Overview
We are seeking a highly skilled and motivated Senior Power Electronics Engineer to join our growing Electrical Engineering team. In this role, you will lead and coordinate the work of a small engineering team while developing advanced power conversion systems for hybrid power solutions, including clean-sheet designs for inverters, converters, and motor control systems. You will play a key role in supporting power electronics integration for next-generation generator sets, hybrid powertrains, and electrified propulsion systems.
Key Responsibilities
At LiquidPiston, we challenge convention and solve hard problems. We move fast, think boldly, and iterate quickly. Our team thrives on collaboration, creativity, and resilience. We take calculated risks and believe that every setback is a steppingstone toward breakthro

Key Responsibilities
- Lead clean-sheet design and development of AC/DC and DC/DC power converters, including bidirectional inverters and battery chargers.
- Perform magnetics and filter design, system-level integration, and EMI hardening for military-grade systems.
- Design and implement high-speed switching power electronics with 4-quadrant motor control and precise AC-DC regulation.
- Conduct EMI/EMC testing, troubleshooting, and compliance verification to DoD and MIL-STD requirements.
- Collaborate with mechanical, firmware, and systems engineers to deliver compact, efficient, and ruggedized power solutions.
- Document designs and results using Microsoft Office tools and contribute to technical reports and presentations.
- Interface with vendors, customers, and multidisciplinary project teams throughout the product lifecycle.
- Bachelor’s or Master’s degree in Electrical Engineering, Power Electronics, or related field.
- Demonstrated expertise in:
- Bidirectional inverters, DC/DC converter topologies, and magnetics/filter design
- EMI hardening and compliance testing for defense applications
- High-speed switching and motor control (4-quadrant)
- Familiarity with AC-DC regulation principles and practical circuit implementation.
- Proficiency with MS Office (Word, Excel, PowerPoint).
- Must be a U.S. Person.
- 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 EAGLE or Altium.
- Firmware development experience (C/C++ preferred).
- Project management skills with experience coordinating across teams and with external stakeholders.
- Flexible PTO to encourage work-life balance and personal well-being
- Comprehensive healthcare coverage: medical, dental, and vision plans
- Equity participation: RSUs for all permanent employees
- 401(k) with match: 100% up to 3%, plus 50% match for 3–5% range
- Growth opportunities: Mentorship, training, and leadership development
