Hermeus is a venture-backed defense aviation company building the fastest aircraft in the world through rapid iterative prototyping and hardware-focused development. The company partners with the Department of War to deliver high-speed capabilities for national defense.
As a Senior Power Electronics Electrical Engineer, you will own the electrical power architecture and components for next-generation supersonic and hypersonic aircraft. This is an end-to-end role spanning concept through implementation, testing, and fielding of flight hardware and ground support systems.
Key responsibilities include:
- Designing and developing power electronics systems for supersonic and hypersonic aircraft applications
- Owning electrical power architecture from concept through implementation and testing
- Collaborating with cross-functional mechanical and electrical engineering teams to architect integrated vehicle power systems
- Supporting systems that provide electrical, fluid, and mechanical power to critical aircraft components
- Serving as a technical bridge between electrical and mechanical engineering disciplines
- Designing flight hardware, ground support equipment, and test systems
- Evaluating, selecting, and integrating commercial off-the-shelf (COTS) and custom hardware solutions
- Working directly with vendors and suppliers to identify and develop suitable components
- Mentoring junior engineers and establishing engineering standards, tools, and best practices
- Supporting hands-on hardware assembly, integration, troubleshooting, and testing
- Participating in rapid prototyping and fast-paced build/test cycles
- Contributing to advancing propulsion and power system capabilities for hypersonic transport
This is a highly hands-on, fast-paced environment focused on solving complex technical challenges at the pace of modern defense requirements.
REQUIREMENTS:
- BS in Electrical Engineering or Mechanical/Aerospace Engineering with significant industry experience developing electrical components and systems
- 5+ years of experience in multiple of the following areas: battery design, motor controller design, harness design and fabrication, design for high EMI environments and mitigations, power conditioning, communication hubs/busses, bus converters, and PCB layout
PREFERRED QUALIFICATIONS:
- Master's degree in Electrical, Mechanical, Aerospace Engineering, or related discipline
- Direct experience with high-voltage DC systems and components (batteries, motors, generators)
- Hands-on experience with HV systems, including proper safety procedures
- Strong working knowledge of aerospace systems engineering practices (requirements development, verification and validation, component qualification, acceptance testing, system diagramming/modeling, risk management)
- Experience executing hardware test and certification campaigns
- Proficiency with relevant software tools: Python, Capital Harness, Siemens NX/Teamcenter, Altium Designer
- Experience with simulation and test tools (Fluke process meters, ammeters, Simulink, ANSYS)
- Familiarity with industry standards: IPC-620, MIL-STD-810, MIL-STD-704, MIL-HDBK-516C, MIL-STD-464D, DO-160G
- Demonstrated project experience designing high power (>5kW) electronic components or distributed systems
- Strong analysis and troubleshooting skills
- Experience with avionics devices and communication protocols (CAN bus, RS-422, ARINC 825) and connectors (D38999)
- Strong ability to collaborate across mechanical and electrical engineering domains
- Proven experience contributing to engineering project teams in fast-paced environments
