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.

Requirements

Bachelor’s degree in electrical engineering or a related engineering discipline.

4+ years of experience in electrical hardware design, avionics integration, instrumentation, control systems, digital communication buses, analog design, power electronics, harness design, or vehicle electrical systems.

Experience creating or interpreting schematics, wiring diagrams, interface control documents, or test procedures.

Strong troubleshooting skills and comfort working hands-on with electrical hardware.

Ability to work cross-functionally with engineering, test, manufacturing, and operations teams.

Bias toward action and willingness to operate in a fast-paced hardware development environment.

Preferred Skills and Experience

Master’s degree in electrical engineering, mechanical engineering, aerospace engineering, or a related discipline.

Experience with embedded systems, device integration, verification and validation, environmental qualification, ground testing, or flight testing.

Experience with avionics devices, sensors, data acquisition, telemetry, instrumentation, or signal conditioning hardware.

Familiarity with tools such as DMMs, oscilloscopes, power supplies, SPICE, MATLAB, LabVIEW, or Ansys.

Experience with Altium Designer, Siemens NX, Teamcenter, Git, Jira, Jama, Confluence, or similar tools.

Familiarity with avionics interfaces and hardware such as RS-485, Ethernet, ARINC-429, CAN, GPS, INS, FPGAs, D38999-style connectors, or similar.

Familiarity with aerospace standards such as IPC-620, MIL-STD-810, MIL-STD-704, MIL-STD-461, MIL-STD-464, MIL-HDBK-516, or DO-160.

Experience with DC power systems, batteries, motors, generators, power distribution, grounding, bonding, or EMI/EMC.

Experience supporting vehicle bring-up, integrated checkout, anomaly resolution, or test operations.

Project experience with aircraft, launch vehicles, spacecraft, UAVs, missiles, defense systems, or other complex hardware platforms.

Ability to travel on short notice to support test campaigns.

U.S. EXPORT CONTROL COMPLIANCE STATUS

The person hired will have access to information and items subject to U.S. export controls, and therefore, must either be a “U.S. person” as defined by 22 C.F.R. § 120.62 or otherwise eligible for deemed export licensing.
