Location: Atlanta, Georgia

Compensation: $138,550 - 187,450 USD / year

About The Role

RF Systems Engineer

Hermeus is a venture-backed defense aviation company reclaiming the lost art of rapid iterative prototyping to build the fastest aircraft in the world today. By prioritizing relentless hardware iteration, we deliver high-speed systems at the pace of the modern battlefield. We work with the Department of War to provide the high-speed capabilities our nation and its allies need to maintain a durable, asymmetric advantage.

About the Role: As an RF systems engineer you will be responsible for identifying RF hardware requirements, creating system architectures, and building/testing/integrating 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).
• 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 procuring and integrating quality RF module and antenna subsystems into our aircraft.
• Perform data analysis of RF systems, generate documentation/slides and present results to team.

Requirements

• Bachelor's degree in electrical engineering or related discipline.
• 4+ years of professional experience designing and testing electrical, antenna and/or RF hardware and systems.
• Experience with RF/Antenna Systems in L/S/C/Ku and Ka-Band frequencies.

Preferred Skills and Experience

• Demonstrated experience working collaboratively in cross-functional teams.
• Strong troubleshooting and problem diagnostic skills
• Understanding of electromagnetic propagation, impedance matching, Smith Chart, VSWR, P1dB, IIP3, NF, and etc.
• Understanding of digital modulation such as QAM, BPSK, QPSK, and SOQPSK or similar.
• Experience working with VNA, spectrum analyzers, RF power meters, and other relevant RF test equipment.
• Experience with test equipment automation and scripting
• Strong hands-on skills including prototyping/soldering and the use of a full range of instrumentation including multimeters, oscilloscopes, current meters, etc
• Support ongoing regulatory filing including FCC, FAA, and AFTRCC.
• Previous Experience on Integration and Test of an RF Systems (of any kind) with Radio as an integral part of RF Systems.
• Master's degree 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.
