Job description
At Relativity Space, we’re building rockets to serve today’s needs and tomorrow’s breakthroughs. OurTerran R vehicle will deliver customer payloads to orbit, meeting the growing demand for launchcapacity. But that’s just the start. Achieving commercial success with Terran R will unlock newopportunities to advance science, exploration, and innovation, pioneering progress that reaches beyondthe 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. Nowis a unique moment in time where it’s early enough to leave your mark on the product, the process, andthe culture, but far enough along that Terran R is tangible and picking up momentum. The mostmeaningful work of your career is waiting. Join us.
About the Team:
The Avionics Test & Operations team is responsible for testing avionics hardware and systems across the entire product lifecycle of Terran R: component-, subsystem-, and vehicle-level. As an Avionics Sr Test Engineer, RF and Navigation at Relativity Space, you will be responsible for designing, developing, and executing avionics testing strategies for our RF and telemetry rocket systems. This includes working closely with the RF avionics design team to identify and troubleshoot any issues and developing automation and testing infrastructure to improve efficiency and effectiveness.
About the Role:
Develop frameworks and infrastructure to conduct qualification and acceptance testing of RF, telemetry, and navigation avionics components, including GPS/GNSS receivers and inertial measurement units (IMUs), on the Terran R launch vehicle
Design equipment to facilitate avionics component testing: simulation circuits, RF signal sources, GPS/GNSS and sensor simulators, auxiliary test equipment, test harnesses, mechanical fixtures and enclosures, and system validation tools
Work with hardware design engineers and software engineers to derive test requirements, develop test methodologies, and establish verification strategies for RF and navigation systems
Create and maintain test plans and procedures for avionics systems that support regulatory and licensing activities with government and regulatory bodies such as the FCC, ITU, and USSF
Integrate, commission, and operate test rack hardware and software to support component- and system-level functional testing of RF, telemetry, GPS/GNSS, and inertial systems
About You:
Undergraduate or graduate degree (BS/MS/PhD) in Electrical Engineering, Computer Engineering, Computer Science, Aerospace Engineering, or a related field
5+ years of experience with RF, navigation, avionics, electronics design, simulation, or test
Experience working with electronics test equipment such as power supplies, DMMs, oscilloscopes, signal generators, and electronic loads
Experience working with RF and/or navigation test equipment such as spectrum analyzers, SDRs, RF signal generators, GNSS/GPS simulators, inertial sensor test equipment, and data recorders
Familiarity with testing and characterization of GPS/GNSS receivers, IMUs, inertial sensors, or other navigation avionics
Strong communication and interpersonal skills
Nice to haves, but not required:
Experience testing or characterizing active RF electronics such as PAs, LNAs, and/or radio transceivers
Experience with GPS/GNSS testing, including signal simulation, receiver characterization, navigation performance, or interference testing
Experience with IMU/inertial sensor testing, calibration, characterization, or hardware-in-the-loop simulation
Experience designing or integrating RF, navigation, or avionics test systems
Familiarity with scripting languages such as Python or MATLAB for data acquisition, recording, automation, and analysis
