Fluid Components Engineer II

Long Beach, California
USD $110,000~$140,000
Software Development

Company Overview:  

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 team is responsible for all fluid systems between the engine and the ground connection that will enable our Terran 1 and R rockets to venture to space. We collaborate closely with virtually every discipline- including our propulsion, structures, launch, and test teams- to deliver a vehicle capable of launching to orbit. We strive for continuous improvement and support the development of our technical hardware and human teammates alike.

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 or higher in relevant engineering discipline (e.g. Mechanical, Aerospace, or Chemical)
  • 2+ years of professional engineering experience
  • Strong engineering fundamentals in thermodynamics, structures, fluid dynamics, and heat transfer
  • Familiarity with programming languages such as Matlab, Python, or C++
  • Exposure to CFD and FEA tools (ANSYS)
  • Proven ability to practically apply engineering fundamentals to solve real, complex problems

Relativity Space offers competitive salary and equity, a generous vacation policy, an annual L&D stipend and more! 

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.
