Our Terran R vehicle will deliver customer payloads to orbit, meeting the growing demand for launch capacity. But that’s just the start. Achieving commercial success with Terran R will unlock new opportunities to advance science, exploration, and innovation, pioneering progress that reaches beyond the known.Joining Relativity means becoming part of something where autonomy, ownership, and impact exist at every level. Here, you're not just executing tasks; you're solving problems that haven’t been solved before, helping develop a rocket, a factory, and a business from the ground up. Whether you’re in propulsion, manufacturing, software, avionics, or a corporate function, you’ll collaborate across teams, shape decisions, and see your work come to life in record time. Relativity is a place where creativity and technical rigor go hand in hand, and your voice will help define the stories we’re writing together. Now is a unique moment in time where it’s early enough to leave your mark on the product, the process, and the culture, but far enough along that Terran R is tangible and picking up momentum. The most meaningful work of your career is waiting. Join us.About The TeamThe 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 RoleDrive 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 launchCreate link budgets for various vehicle RF systemsModel antenna radiation patterns and simulate vehicle-level antenna performanceDevelop the architecture for vehicle ground and vehicle RF systems, including S and L band systemsSelect COTS parts or design custom components such as antennas, RF passives, PAs and LNAs, transmitters/receivers, and GSESupport regulatory and licensing activities with government and regulatory bodies such as the FCC, ITU, and USSFAbout YouBachelors degree in Electrical Engineering, Computer Engineering, or a related field5+ years of experience in RF and telemetry system engineeringExperience with 3 or more of the following:Antenna design and modeling tools such as Ansys HFSSDeveloping link budgetsDesign and selection of RF passive components such as couplers and filtersDesign 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 recordersExperience communicating deeply technical topics with individuals from different disciplinesNice To Haves, But Not RequiredFamiliarity with telemetry standards standards such as IRIG-106Experience designing active RF electronics such as PAs, LNAs, and/or radio transceiversSoftware engineering fluency and experience with C++, Python, and/or MATLABExperience establishing a ground station network for launch vehicles or satellite systemsAt Relativity Space, we are committed to transparency and fairness in our compensation practices.
