Avionics System Integration Engineer II, Test Platforms

About the Team: 

The Avionics System Integration and Test team is responsible for integrating and validating the avionics hardware on a system-level scale for the Terran R rocket. The Avionics System Integration and Test team defines and oversees avionics system checkouts during critical stages such as vehicle build and integration, stage hotfire, and launch operations. The team also owes the design, build, and validation of integrated testbeds such as full-system Vehicle HITL and subsystem HITLs (Engine, Power, RF/Navigation).

As an Avionics Systems Test Engineer II, Test Platforms at Relativity Space, you will be responsible for designing, developing, and maintaining the Hardware-in-the-Loop (HITL) testbeds for avionics subsystems. This will involve working closely with the avionics and flight software teams to understand their testing needs and develop appropriate test systems. You will also be responsible for designing the HITL test infrastructure, maintaining configuration of the HITL platform, developing validation procedures, and providing feedback to design teams and system integration.

About the Role:

• Design and build a Hardware-in-the-Loop (HITL) testbed to conduct vehicle mission simulations
• Collaborate with hardware and software engineers to derive simulation platform requirements
• Oversee the integration of Avionics electrical systems, simulation hardware and software, and auxiliary support equipment
• Develop, document, and execute Avionics system verification/validation plans
• Drive data reviews for verification/validation testing on HITL platforms
• Support Vehicle Software releases and Run-for-Record on the HITL platforms

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 complex system design, testing, and architecture
• Experience working with electronics test equipment such as power supplies, data acquisition systems (NI/Beckhoff), DMMs, oscilloscopes, signal generators, and electronic loads
• Understanding of engineering requirements capture and the verification/validation test planning process
• Familiarity with common communication protocols such as Ethernet, CAN, UART, SPI, etc.
• Familiarity with scripting languages such as Python or MATLAB for data acquisition/recording and analysis

Nice to haves but not required:  

• Previous experience with hardware-in-the-loop (HITL) test systems
• Experience with complex operations (flight test, launch operations, large-scale manufacturing, etc.)
• Familiarity with wire harness design Ability to read and interpret schematics and wiring diagrams
