Sr. RF Engineer
Hermeus
Atlanta, GA, USA
Posted on Dec 11, 2024
Hermeus is an aerospace and defense technology company founded to radically accelerate air travel by delivering hypersonic aircraft. The company aims to develop hypersonic aircraft quickly and cost-effectively by integrating hardware-rich, iterative development with modern computing and autonomy. This approach has been validated through design, build, and test of the company’s first combined turbojet-ramjet engine and is now being scaled through its first flight vehicle program, Quarterhorse. Hermeus is also developing Darkhorse — an uncrewed hypersonic aircraft designed to deliver unique asymmetric capabilities to the warfighter.
We are looking for an RF systems engineer focused on identifying RF hardware requirements, creating system architectures, and building/testing the RF solutions – both on the aircraft and ground station. This position will require strong fundamentals, wide-breadth design experience, and efficient troubleshooting skills. You’ll be responsible for high-ownership technical delivery while working with a multi-disciplinary team of engineering, manufacturing, and quality professionals.
Responsibilities:
- Simulate/model RF hardware for communication systems and sensors/instruments.
- Develop test concepts and test procedures for RF and Environmental testing, including far field and near field measurements (plus vibration, shock, thermal and thermal vacuum).
- Design and validate RF electronic circuits and systems such as RF amplifier, communications front-end, LNA, Mixer, BUCs, Feed network, and etc.
- Define hardware architecture and specifications for the RF system blocks, interfaces, and housing. Design, build and test microwave circuits and assemblies.
- End-to-end design validation and testing of RF product performance. Lead and conduct troubleshooting or root cause hardware performance challenges.
- Work with manufacturing and production teams on producing and integrating quality RF/Antenna subsystems into our aircrafts.
Basic Qualifications
- Bachelor's degree in Electrical Engineering or related discipline.

- Understanding of electromagnetic propagation, impedance matching, Smith Chart, VSWR, P1dB, IIP3, NF, and etc.
- Understanding of digital modulations such as QAM, BPSK, QPSK, and SOQPSK or similar.
- Experience working with VNA, spectrum analyzers, RF power meters, and other relevant RF test equipment.
- Strong hands-on skills including prototyping/soldering and the use of a full range of instrumentation including oscilloscopes, spectrum analyzers, network analyzers etc.
- Support ongoing regulatory filling including FCC, FAA, and AFTRCC.
- Previous Experience on Integration and Test of an RF Systems of a kind with Radio as an integral part of RF Systems.
- Master's degree or PhD preferred with emphasis in Antenna, Electromagnetic theory and/or microwave circuits.
- Experience using in HFSS (or similar antenna simulation tools).
- Familiarity with Antenna design, including types and tradeoffs.
- EMI/EMC testing per MIL-STD-461.
- Prior experience working on an airborne vehicle.
