Data & Controls Systems Engineer

At Relativity Space, we’re building rockets to serve today’s needs and tomorrow’s breakthroughs. Our Terran R vehicle will deliver customer payloads to orbit, meeting the growing demand for launch capacity. But that’s just the start. Achieving commercial success with Terran R will unlock new opportunities to advance science, exploration, and innovation, pioneering progress that reaches beyond the 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. Now is a unique moment in time where it’s early enough to leave your mark on the product, the process, and the culture, but far enough along that Terran R is tangible and picking up momentum.

The most meaningful work of your career is waiting. Join us.

The Factory Test team is responsible for hardware testing in our Long Beach facilities. We use our breadth of experience and collaborative engineering approach to support everything from very large structural tests to precise valve actuation. To that end, we design, build, and operate all test assets in Long Beach from initial concept to test execution. If you enjoy working on a multi‑disciplinary team with a broad mandate and want to put hands on hardware, then this is the team for you.

As a Data & Control Systems Engineer, you will be responsible for design, integration, checkout, and operation of data systems at our Long Beach facilities. The projects you work on will run test systems across the factory ranging from quick and scrappy development test setups to large permanent infrastructure. You will be required to be hands on with the hardware, working side‑by‑side with our technician team to build and debug your projects.

Once your hardware is built, you will also work closely with our operations and software teams to integrate it with our in‑house data and controls platform - including writing and debugging automation to control real hardware.

• Setup and checkout test stands for operations – ranging from testing critical valves that will be used to run the Aeon R engine, to putting Terran R through its paces during a full stage structural test, and everything in-between
• Working to understand the needs of a new test campaign, then getting a data acquisition and controls system set up, configured, checked, and ready to test – collecting the right data, at the right time, with the right context
• Selection, integration, and configuration of instrumentation on a test stand
• Design data acquisition and control systems for various test stands, including panel layouts, power and load analysis, fabrication drawings, and instrumentation lists
• Solving a wide range of technical challenges, across broad ranges of timeframe, complexity, cost, and long‑term impact

• Bachelor’s degree in Electrical Engineering, Computer Engineering, or related field
• Strong engineering fundamental knowledge
• Ability to design electrical control cabinets, wiring harnesses, and select instrumentation
• Demonstrated ownership, accountability, and success in delivering complex product with multiple stakeholders
• No previous aerospace experience is required.

• Familiar with specifying, selecting, and integrating sensors and actuators such as pressure transducers, RTDs, strain gages, thermocouples, solenoid valves, accelerometers, microphones, etc
• Familiar with scripting languages such as Python or MATLAB for performing analysis or writing automation tools
• Familiarity with data and control systems (SCADA, PLC’s, NI, Beckhoff, etc.)
• Familiar with communications methods such as, but not limited to, SPI, Ethernet, Ether
