Job Description:
Job Description Job Description 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 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 leverages close partnership between 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

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
