About the position

As a Propulsion Test Engineer II at Relativity Space, you will play a pivotal role in the design and operation of rocket engine test stands for our Terran R engines and stages. This position is based at the Stennis Space Center, where you will be part of a dedicated team responsible for building and operating state-of-the-art test facilities. Your work will directly contribute to the success of the Terran 1 launch and other innovative projects. You will engage in hands-on activities, including the construction and commissioning of test stands, and participate in test campaigns to ensure our hardware meets flight qualifications. In this role, you will have the opportunity to design advanced propulsion test stands, which involves 3D modeling, conducting thermal and structural analysis, and creating fabrication drawings and detailed work instructions. You will supervise the construction and initial operations of these facilities, solving a variety of technical problems that may arise during the process. Additionally, you will support operations on existing test stands and implement improvements to enhance their performance. On the operations side, you will create and optimize test sequences and procedures, conduct complex propulsion test operations, and directly control telemetry from the test stands. Your ability to analyze real test data will be crucial in developing new rocket engine propulsion designs. This position may require occasional travel to production and launch locations, with travel expectations of up to 25%.

Responsibilities

  • Design advanced propulsion test stands including 3D modeling, fluids, structural, and thermal analysis.
  • Create fabrication drawings, fluids P&IDs, component lists, and detailed work instructions.
