Hermeus is a high-speed aircraft manufacturer focused on the rapid design, build, and test of high-Mach and hypersonic aircraft for the national interest. Working directly with the Department of Defense, Hermeus delivers capabilities that will ensure that our nation, and our allies, maintain an asymmetric advantage over any and all potential adversaries.

The

Mission Systems Engineering Team develops the architecture, interfaces, and hardware/software integration that enable Hermeusaircraft to execute missions. As an

Avionics Engineer on this team, you will design, integrate, and validate avionics components and mission hardware that interface with the

Mission Management System (MMS) platform. You will work at the boundary between airborne hardware, mission subsystems, and command-and-control infrastructure—ensuring that third-party sensors, communication devices, autonomy modules, and onboard systems integrate into a coherent mission capability.

Responsibilities:

Design, integrate, and validate avionics hardware and electronics that interface with the Mission Management System and other mission subsystems

Define electrical architectures, signal flows, wiring interfaces, and hardware integration points across aircraft and ground mission systems

Evaluate, select, and qualify mission hardware components—such as radios, processors, network devices, autonomy payloads, and third-party subsystems

Develop interface control documentation, electrical schematics, and integration requirements for avionics and mission hardware

Perform bring-up, testing, and troubleshooting of avionics components in lab, rig, simulation, and aircraft environments

Collaborate with software, autonomy, communications, and systems engineers to ensure deterministic and reliable data exchange between onboard systems and the MMS platform

Support system-level tests, mission rehearsals, and hardware-in-the-loop environments to validate hardware/software interoperability

Identify integration risks and drive resolution through iterative testing, documentation, and cross-functional coordination

Minimum Requirements:

Bachelors degree in Electrical Engineering, Computer Engineering, Aerospace Engineering, or a related technical field

5+ years of experience designing, integrating, or testing avionics or mission-critical hardware systems

Hands-on experience with aircraft electronics, embedded systems, communication interfaces, or mission hardware integration

Proficiency with electrical schematics, wiring diagrams, harness design, and hardware bring-up workflows

Familiarity with communication buses and protocols (e.g., RS-422, Ethernet, CAN, ARINC, MIL-STD interfaces)

Experience integrating hardware in environments with evolving requirements, incomplete specifications, and cross-disciplinary dependencies

Strong troubleshooting and diagnostics skills with oscilloscopes, logic analyzers, or equivalent instrumentation

Effective communication skills and the ability to work across software, systems, and operations teams

Preferred Skills & Experience:

10+ years of avionics or mission hardware integration experience

Experience integrating autonomy payloads, onboard processors, sensors, RF systems, or tactical communications equipment

Familiarity with RF/SATCOM/LOS radios, encryption modules, or datalink terminals

Experience with structured system engineering processes, interface control documents, and hardware qualification/acceptance testing

Knowledge of environmental, EMI/EMC, or aerospace certification standards (DO-160, MIL-STD-810, etc.)

Experience working in rapid development or startup environments where iteration speed and integration agility are critical

Background interfacing avionics hardware with C++ or embedded software systems
