Senior RF Systems Engineer

AtlantaOn-siteFull-time

AI Summary

Design, build, test, and integrate RF hardware and antenna systems for high-speed aircraft and ground stations, including simulation, prototyping, and end-to-end validation.

About this role

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.

    • 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 filling 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.
  • Prior experience working on an airborne vehicle.
  • Experience in a startup or agile development environment.
  • Experience with Python or other scripting languages to aid automation, data analysis, etc
  • Ability to travel on short notice to support test campaigns
