Hermeus is a venture-backed defense aviation company focused on building high-speed aircraft through rapid iterative prototyping. The company works with the Department of War to deliver advanced capabilities for national defense.
As an RF Systems Engineer, you will be responsible for designing, developing, and integrating RF systems for advanced aircraft platforms. This is a hands-on role that bridges architecture, hardware integration, and testing across multiple engineering disciplines.
Key Responsibilities:
- Define RF system requirements, architectures, interfaces, and verification approaches for communication, telemetry, navigation, and sensor systems
- Develop block diagrams, link budgets, interface documentation, test plans, and integration procedures
- Design, build, integrate, and test RF hardware including antennas, radios, RF modules, cabling, connectors, and supporting electrical assemblies
- Execute comprehensive RF testing including conducted RF tests, antenna measurements, environmental testing, and system-level validation
- Troubleshoot RF performance issues and drive corrective actions through design, build, integration, and test cycles
- Support aircraft and ground station integration, ground test, flight test, and off-nominal troubleshooting
- Analyze RF test and flight data, document results, and communicate risks and recommendations to cross-functional teams
- Support regulatory coordination related to FCC, FAA, AFTRCC, and other RF spectrum or flight test requirements
You will work closely with avionics, GNC, flight software, manufacturing, quality, test, and operations teams to deliver reliable systems at the pace of modern defense requirements.
REQUIREMENTS:
- Bachelor's degree in electrical engineering or related field
- 4+ years of experience with RF, antenna, radio, telemetry, communication, or electrical systems
- Experience with RF/electrical test equipment (VNAs, spectrum analyzers, power meters, signal generators, oscilloscopes, multimeters)
- Strong RF fundamentals including propagation, impedance matching, VSWR, gain/loss, noise figure, filtering, and link performance
- Experience developing RF test plans, procedures, setups, or data analysis workflows
- Strong hands-on troubleshooting skills in lab, integration, or test environments
- Ability to work cross-functionally and communicate technical tradeoffs, results, risks, and recommendations
- Bias toward action and willingness to work hands-on with hardware
PREFERRED EXPERIENCE:
- Master's degree focused on antennas, RF systems, microwave circuits, communications, or related field
- Experience with L, S, C, Ku, or Ka-band systems
- Aerospace, defense, aircraft, spacecraft, UAV, missile, or flight test experience
- Experience with antennas, telemetry, radios, navigation, communication links, or RF instrumentation
- Familiarity with modulation schemes (QAM, BPSK, QPSK, SOQPSK)
- Experience with HFSS, CST, FEKO, ADS, MATLAB, Python, or similar tools
- Hands-on prototyping skills including soldering, cable fabrication, and connectorization
- EMI/EMC or qualification testing experience (MIL-STD-461, MIL-STD-810, MIL-STD-704, MIL-STD-464, DO-160)
- Startup, rapid prototyping, or agile hardware development experience
- Ability to travel on short notice for integration, ground test, or flight test support
Note: Candidates must be U.S. persons as defined by export control regulations or otherwise eligible for deemed export licensing.
