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 Hermeus aircraft 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.

Job Responsibility

  • 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

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

Nice to have

  • 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

What we offer

  • 100% employer-paid health care
  • 401k & retirement plans
  • Unlimited PTO
  • Weekly paid office lunches
  • Fully stocked breakrooms
  • Stock options
  • Paid Parental Leave
