At Relativity Space, we have two audacious goals: to build the next great commercial launch company with Terran R and to become America's leading force in additive manufacturing innovation. Both contribute to our long-term vision of creating humanity’s industrial base on Mars, paving the way for interplanetary life to expand the possibilities of the human experience. This journey begins right here on Earth – where we design, build, and fly rockets to deliver customer payloads to orbit. Terran R, our medium-to-heavy lift reusable rocket, fulfills the growing demand for launch capacity, thanks to our iterative approach that accelerates design, testing, and development while minimizing costs. While our groundbreaking research and development in 3D printing pushes the boundaries of large-scale additive manufacturing.
Your journey with us is more than just a job – it’s an opportunity to shape the future of aerospace technology, additive manufacturing, and the human experience alongside a community of passionate, creative individuals. Join us on this extraordinary journey, as we work together to transform our vision into reality.
About the Team:
The Stage Fluids and Components team is responsible for all fluid systems and components on the Terran R launch vehicle. This includes systems for the liquid oxygen and liquid natural gas propellants as well as the supporting helium and nitrogen gasses. We also design the individual valves that are used within these systems on the stages and engines. This requires us to integrate our designs with those of the structures, propulsion, avionics hardware teams. It also requires us to work closely with the GNC and performance teams to ensure that our systems can meet the requirements of launching and landing a reusable rocket. Finally, we also work closely with the manufacturing and test teams to ensure our hardware is adequately built and tested.
About the Role:
In this role you will be responsible for the design, analysis, development and qualification of flow control devices for the Aeon R engine and Terran R launch vehicle.
Specific responsibilities will include:
- Design and analysis of clean sheet of cryogenic, pneumatic, proportional, or solenoid valves
- Detailed fluid, thermal, and structural analysis of piece parts and assemblies
- Development and qualification test planning and execution of internally developed valves
- Engine and vehicle test support for existing flow control products
- Conducting trade studies to produce architectures and designs that satisfy system requirements
About You:
- Bachelor’s degree in relevant engineering discipline (Mechanical or related)
- 2+ years of professional engineering experience
- Demonstrated experience applying thermodynamics, structures, fluid dynamics, and heat transfer
- Experience with programming languages such as Matlab, Python, or C++
- Experience with CFD and FEA tools (ANSYS)
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.
