Senior RF Development Engineer

About the Team: The Avionics team is responsible for the full lifecycle of Terran R's nervous system, designing, building, testing, installing, and operating the hardware that connects and controls every major electrical system on the vehicle and ground.

The team's structure intentionally combines avionics design, manufacturing, and test to enable rapid iteration and feedback loops.

Engineers are deeply embedded into other functions within Relativity, working closely with propulsion, GNC, fluids, and stage engineering teams to ensure seamless integration and operation.

Now is a unique time to join: you'll get to help shape Terran R's fundamental avionics architecture and be given a high degree of ownership on components that will fly.

About the Role: * Drive the development of the flight and ground RF & Telemetry system for our launch vehicles through all phases of the development process including design, integration, test, and launch * Create link budgets for various vehicle RF systems * Model antenna radiation patterns and simulate vehicle-level antenna performance * Develop the architecture for vehicle ground and vehicle RF systems, including S and L band systems * Select COTS parts or design custom components such as antennas, RF passives, PAs and LNAs, transmitters/receivers, and GSE * Support regulatory and licensing activities with government and regulatory bodies such as the FCC, ITU, and USSF About You: * Bachelors degree in Electrical Engineering, Computer Engineering, or a related field * 5+ years of experience in RF and telemetry system engineering * Experience with 3 or more of the following: * Antenna design and modeling tools such as Ansys HFSS * Developing link budgets * Design and selection of RF passive components such as couplers and filters * Design and integration of RF systems consisting of radio transmitters and receivers, LNAs, PAs, couplers, filters, etc.

* Working with RF test equipment such as spectrum analyzers, SDRs, and data recorders * Experience communicating deeply technical topics with individuals from different disciplines Nice to haves, but not required: * Familiarity with telemetry standards standards such as IRIG-106 * Experience designing active RF electronics such as PAs, LNAs, and/or radio transceivers * Software engineering fluency and experience with C++, Python, and/or MATLAB * Experience establishing a ground station network for launch vehicles or satellite systems
