Sr RF Development Engineer
Relativity Space
At Relativity Space, we’re building rockets to serve today’s needs and tomorrow’s breakthroughs. 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 Team:
The Avionics team is responsible for all aspects of the electrical design on the rocket, from electronics, interconnects, associated mechanical design, testing and initial production. This team's scope includes the flight computers, power systems, RF systems, PCB design, autonomous flight safety systems, and telemetry. This team works on complex electrical systems that require modularity and flexibility, and are critical to the successful launch of Terran R, and beyond!
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
