Senior Avionics Test Systems Engineer, HITL

Company Overview:  

A rocket company at the core, Relativity Space is on a mission to become the next great commercial launch company. Meeting the needs of a growing demand for space infrastructure, our rockets will revolutionize how we connect and communicate on Earth by getting satellites to space. We have developed a vertically integrated technology platform in which we leverage additive manufacturing, artificial intelligence, and autonomous robotics to 3D print rockets. Our unique approach enables rapid product iteration, allowing us to push the boundaries of what's possible today and unlock the full potential of 3D printing for tomorrow. Join us on this extraordinary journey, as we work together to transform our vision into reality.

Team:  

The Avionics Test & Operations team is responsible for testing avionics hardware and systems across the entire product lifecycle of Terran 1 and Terran R: component-, subsystem-, and vehicle-level.

As a Senior Avionics Test Systems Engineer, HITL at Relativity Space, you will be responsible for designing, developing, and maintaining the Hardware-in-the-Loop (HITL) test/simulation platform 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 setting up and conducting tests, analyzing test data, and providing feedback to the design and development teams.

What you’ll do: 

• 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   
• Support vehicle troubleshooting and validate changes by creating and executing integrated testing on HITL
• Develop, document, and execute Avionics system verification/validation plans 

What you need to know:  

• Undergraduate or graduate degree (BS/MS/PhD) in Electrical Engineering, Computer Engineering, Computer Science, Aerospace Engineering, or a related field
• 3+ years of experience with complex system design and architecture
• Familiarity with data acquisition and control system platforms such as NI, Beckhoff, or similar
• Experience working with electronics test equipment such as power supplies, 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
• Strong communication and interpersonal skills 

Nice to haves but not required:  

• Experience with complex operations (flight test, launch operations, large-scale manufacturing, etc)
• Previous experience with hardware-in-the-loop (HITL) test systems
• Familiarity with wire harness design
• Knowledge of electrical engineering principles and how they apply to avionics systems
• Ability to read and interpret schematics and wiring diagrams
• Experience with scripting languages such as Python or MATLAB for automating tests and data analysis
• Strong problem-solving and communication skills

Relativity Space offers competitive salary and equity, a generous vacation policy, an annual L&D stipend and more!
