Avionics Electrical Engineer

Hermeus is a venture-backed defense aviation company reclaiming the lost art of rapid iterative prototyping to build the fastest aircraft in the world today. By prioritizing relentless hardware iteration, we deliver high-speed systems at the pace of the modern battlefield. We work with the Department of War to provide the high-speed capabilities our nation and its allies need to maintain a durable, asymmetric advantage.

About the role:

This is a hands-on, cross-functional role supporting GNC, power distribution, instrumentation, communications, RF systems, flight software, test, manufacturing, and vehicle integration. You will own detailed hardware design while also understanding how that hardware performs at the subsystem and integrated vehicle level.

Responsibilities

• Design, analyze, integrate, and test avionics and electrical systems for flight vehicles, ground test assets, and supporting infrastructure.
• Own electrical hardware from concept through design, procurement, build, checkout, qualification, and vehicle integration.
• Develop schematics, wiring diagrams, harness/interface definitions, test plans, procedures, and technical documentation.
• Support architecture trades across power distribution, instrumentation, controls, data acquisition, communication buses, and RF interfaces.
• Work with GNC, flight software, propulsion, structures, hydraulics, test, manufacturing, and operations teams to define requirements and integrated solutions.
• Perform electrical design analysis, including power budgets, signal integrity, thermal considerations, grounding/bonding, and interface compatibility.
• Bring up, troubleshoot, and modify electrical systems at the bench, subsystem, and vehicle level.
• Support ground test, environmental test, integrated vehicle test, and flight test campaigns.
• Maintain configuration control over avionics hardware, drawings, wiring diagrams, work instructions, test procedures, and as-built documentation.
• Support design reviews, test readiness reviews, failure investigations, and risk mitigation planning.
• Work hands-on with technicians, test engineers, and manufacturing teams to quickly resolve issues and keep hardware moving.
