Job Description
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.
About the Team:
The Stage Fluids team is responsible for the design and delivery of 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 not on isolated parts but integrated functionality. Working on-site at the factory means you’re never far from the hardware enabling rapid iteration and tight feedback loops across design and manufacturing. You won’t just be handed requirements: 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:
In this role you will be responsible for the hardware design and implementation of that hardware into vehicle fluid systems ensuring a reliable and efficient operation of our Terran R launch vehicle. Your primary tasks will be focused on:
- Design and analysis of clean sheet of pressure components for launch vehicle fluid and propulsion systems
- Detailed fluid thermal and structural analysis of piece parts and assemblies
- Development and qualification test planning and execution of internally developed components
- Conducting trade studies to produce architectures and designs that satisfy system requirements
About You:
- Bachelor’s degree (Mechanical Engineering or relevant)
- 5+ years of experience working with fluids system component design
- Direct experience applying engineering fundamentals in thermodynamics structures fluid dynamics and heat transfer
- Experience with CFD and FEA tools (ANSYS)
- Project experience with all the following:
- Experience with a commercial CAD package (NX CREO Solidworks)
- Experience designing fluid system pressure components (fittings seals valves regulators etc.) and qualifying them for aerospace applications
- Experience with FEA (ie. ANSYS FEMAP) tools to analyze component structural margins
Nice to haves but not required:
- Experience with internal flow CFD to assess component performance
At Relativity Space we are committed to transparency and fairness in our compensation practices. Actual compensation will be determined based on experience qualifications and other job-related factors.
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! To see some of the benefits & perks we offer please visit here.
