Company Overview:

A rocket company at the core, Relativity Space is on a mission to become the next great commercial launch company. Meeting the needs of a growing demand for space infrastructure, our rockets will revolutionize how we connect and communicate on Earth by getting satellites to space. We have developed a vertically integrated technology platform in which we leverage additive manufacturing, artificial intelligence, and autonomous robotics to 3D print rockets. Our unique approach enables rapid product iteration, allowing us to push the boundaries of what's possible today and unlock the full potential of 3D printing for tomorrow. Join us on this extraordinary journey, as we work together to transform our vision into reality.


Relativity seeks a highly talented Turbomachinery Engineer to join a rapidly growing space startup. This role falls under the Turbomachinery team. We are responsible for designing, manufacturing, and testing the fuel and oxidizer turbopumps for the Aeon-R engine. This position will provide outstanding technical contribution to the development of the Terran R launch vehicle, as well as helping to build a world-class turbomachinery team. A high degree of autonomy and initiative is required.

What you’ll do:

Our mission is to change people’s conception of the way rockets are built and flown. As a Turbomachinery Engineer, you will develop the assemblies for the fuel and oxidizer turbopumps of the Aeon-1 and Aeon-Vac engines. You will collaborate closely with the propulsion development and manufacturing teams to incorporate improvements into future designs. In order to be successful in this role, you should be someone who thrives in ambiguity and is able to drive their own projects to completion. You must have the passion, tenacity and resolve to work through challenging issues unique to rocket turbopumps. We are looking for someone multifaceted, and capable of working at the interfaces of design, development, and analysis of turbomachinery. Ideally, you are someone who has come from a fast paced, aerospace environment, having completed difficult projects while collaborating effectively with multidisciplinary groups.

What you need to know:

In order to be successful in this role, you should have the following:

  • Degree in engineering or related technical field and 2+ years of relevant experience
  • Proficiency in Siemens NX and Teamcenter
  • Strong knowledge of GD&T
  • Ability to perform basic structural, thermal, and/or fluid analysis using ANSYS
  • Knowledge of turbomachinery design and analysis practices
  • Experience managing large CAD assemblies
  • Ability to create drawings quickly and coordinate getting parts made either by external suppliers or in-house
  • Strong communication skills and ability to write work instructions
  • Knowledge of turbopump assembly procedures, including rotor balancing, interference fits, clearance checks, structural proofing, and leak checks

Nice to haves but not required:

  • Degree in engineering or related technical field and 3+ years of relevant experience
  • Experience performing turbomachinery analyses (bladed CFD, structural, modal, rotordynamics)
  • Experience designing bladed turbopump components (inducers, impellers, turbines)
  • Experience in a startup or agile development environment
  • Experience working in a flight development program

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