Avionics Engineer - Mission Systems

Job Description

Job Description

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
