Engine Systems & Test Team - Combustion Device Test Lead
role at
Relativity Space 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. About The Team
The Propulsion team at Relativity is focused on developing and delivering highly performant and manufacturable engines for Terran R. Engineers are responsible for the entire lifecycle of their parts, from initial design through production to qualification and flight. About The Role
This role is on the Component Test Team, within the Engine Systems & Test team. Our broader team is responsible for developing the Aeon engine series at the system level. The Component Test Team is primarily responsible for testing of combustion devices. We collaborate closely with propulsion design engineers, our manufacturing team, our Stennis test team, and our Cape launch team to deliver engines that will successfully propel the Terran rocket to orbit. In the test part of your role, you will serve as a Responsible Engineer for propulsion test articles. These will primarily be combustion devices but may also include valves, heat exchangers, or other components. You will develop test plans in collaboration with product owners, and you will execute test campaigns with our Stennis team, troubleshooting technical puzzles along the way. You will own the exploratory operation of new and existing test article designs, diving deep into the evaluation of test hardware behavior in support of continuous engine development and certification. This role is extremely varied day-to-day and, in addition to overall campaign ownership, can include writing test sequences, reviewing data, hands-on work with test articles, writing code, sitting console for hotfire tests, designing tooling, and more. You will also lead a small team of engineers with similar responsibilities as the above. This will require mentorship, project management, establishing priorities, communicating with leadership, providing technical guidance, and recruiting. Work Schedule & Travel
This role is full-time onsite in Long Beach, CA, and requires an average of 25% travel to our test & launch sites. This role may occasionally require weekend work or travel for critical milestones. About You
Bachelor’s degree in a science, engineering, or technology field 4+ years relevant experience in a complex engineering system development and/or test environment Experience with: Applying engineering fundamentals in fluid mechanics & thermodynamics Problem-solving Working in a collaborative environment Exposure to test operations environments Experience designing, analyzing, testing, or developing at least one of the following: combustion devices, valves, heat exchangers, or instrumentation Leadership potential, which could be demonstrated e.g., through mentoring, managing complex interdisciplinary projects, supporting continuous improvement of the people around you, or participating in growing your team through hiring Compensation
Compensation is only one part of our total rewards package. Relativity Space offers competitive salary and equity, a generous PTO and sick leave policy, parental leave, an annual learning and development stipend, and more! Hiring Range : $146,000—$187,000 USD We are an equal opportunity employer and value diversity at our company. We do not discriminate on the basis of race, religion, color, national origin, gender, sexual orientation, age, marital status, veteran status, or disability status.
