Senior Avionics Test Engineer, RF and Navigation

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
