Relativity
Overview
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. 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. You’ll collaborate across teams, shape decisions, and see your work come to life in record time. 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. About the Team
The Stage Fluids team designs and delivers the propellant, pressurant, pneumatics, and other fluid systems that turn structures into functioning rockets. The team has full ownership across design, production, test, and flight, maintaining a holistic view of Terran R, focused on integrated functionality rather than isolated parts. Working on-site at the factory enables rapid iteration and tight feedback loops across design and manufacturing. You’ll be expected to ask the right questions, collaborate with partners across the company, and ultimately find the best solutions for Terran R. About the Role
You will be part of developing the architecture for the upcoming Terran R vehicle and will be responsible for charting the company’s path for gas storage on a reusable rocket—both near term and long term. Here are some examples of projects you could be working on: Partnering with third party vendors in the design and analysis of gas storage COPVs Working with other thermo-fluid engineers on vehicle gas system design and operation Establishing test campaigns for qualification and acceptance of COPVs Performing tests and reviewing data Supporting integration COPVs on the rocket Selecting, vetting, and managing vendors Performing trade studies to improve gas storage solutions for near-future vehicles Assessing long-term COPV design and manufacturing plans About You
Undergraduate degree in engineering or technical discipline 58+ years of relevant technical experience Experience applying pressure vessel engineering fundamentals Experience applying knowledge of fluid and mechanical system design and operation Nice to haves, but not required
Experience working with COPVs or other composite structures Experience in a creative and fast-paced development environment, working with autonomy Experience with CAD Experience with launch vehicle systems Compensation and Equal Opportunity
We are committed to transparency and fairness in our compensation practices. Actual compensation is determined based on experience, qualifications, and other job-related factors. Compensation is one part of our total rewards package, which includes competitive salary and equity, PTO and sick leave, parental leave, an annual learning and development stipend, and more. See the full benefits information on our site. We are an equal opportunity employer and value diversity. We do not discriminate on the basis of race, religion, color, national origin, gender, sexual orientation, age, marital status, veteran status, or disability status.
