Company Overview:

Relativity is the first and only company to automate aerospace manufacturing by integrating intelligent robotics, software, and proprietary metal 3D printing technology. Disrupting 60 years of aerospace, Relativity offers a radically simplified supply chain, building a rocket with 100x fewer parts in less than 60 days. Our long-term goal is to upgrade humanity’s industrial base on Earth and on Mars.


The Vehicle Engineering Team is responsible for the design, analysis, and validation of our launch vehicle. As a Fluids Engineer, you will be solving the toughest thermal fluids challenges on the rocket as part of a world-class engineering hardware team.

You will work collaboratively with propulsion, GNC, manufacturing, test, launch, and other teams to design all fluids systems necessary to successfully launch and recover a rocket. A high degree of autonomy along with an ability to prioritize work in our fast-paced environment is required. We believe varied perspectives & backgrounds strengthen our team. Prior experience in aerospace is not required

What you’ll do:

In this role, you will be responsible for the mechanical and structural implementation of the stage fluid systems, ensuring a reliable and efficient operation of our Terran R launch vehicle.

  • Fluids routing and design trade studies
  • Fluids hardware mounting structure design
  • Fluid system hardware mechanical verification analysis including both hand calcs and FEA
  • Structural design of mounting hardware for various fluid system component and routing
  • Incorporate 3D printing methods and in fluid system mechanical design
  • Design for Manufacturing (DFM) and Design for Assembly (DFA)

The right person for this role will need to be someone who enjoys leading the way for the team on exploring new methods and design approaches. They will have end to end ownership of their designs and immediately see hardware you designed come to fruition. They must be flexible to changes in strategic direction and willing to take full ownership of their projects to ensure we as a company are producing the best possible product while incorporating innovative production methods into their designs.
