Job description

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:

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 Test Engineer at Relativity Space, you will be responsible for designing, developing, and executing avionics testing strategies for our rocket systems. This includes working closely with the avionics design team to identify and troubleshoot any issues, and developing automation and testing infrastructure to improve efficiency and effectiveness.

  • Responsible engineer for avionics system-level integration, design validation, test, and operations
  • Coordinate test efforts to validate avionics system and subsystem design, including power system validation, fault tolerance and isolation behavior, vehicle network behavior, software validation, etc.
  • Develop vehicle-level avionics CONOPs, go/no-go criteria, system automation, and operator manuals
  • Support the development and operation of Avionics integrated system testbeds
  • Support on-console test operations and data review for the avionics system during stage-level test and launch operations

About You:

  • Undergraduate or graduate degree (BS/MS/PhD) in Electrical Engineering, Computer Engineering, Computer Science, Aerospace Engineering, or a related field
  • 5+ years experience with integrated systems test, such as flight test, hardware or software design validation, or development of hardware in the loop test platforms
  • Understanding of engineering requirements capture and the verification/validation test planning process
  • Experience testing, validating, and troubleshooting complex integrated electrical and software systems
  • Experience with scripting languages such as Python or MATLAB for data acquisition/recording and analysis

Nice to haves but not required:  

  • Familiarity with wire harness design tools such as Zuken
  • Familiarity with CAD tools such as NX and Teamcenter
  • Familiarity with a PCB design modeling tool such as Altium Designer
  • Familiarity with common communication protocols such as Ethernet, CAN, UART, SPI, etc.
