Engine Systems Design & Analysis Team- Principal Propulsion Analyst

About the Team:

The Propulsion team at Relativity is responsible for the successful development of the engines that will power the Terran R vehicle. We own their design from concept through to launch and reuse. Our team partners heavily with Manufacturing, Test, Launch, and Integration teams, striving to develop our engines in record time and to support Terran R's first launch in 2026. As part of this team, you will help build, test, and iterate on the full product lifecycle of our Aeon-R engine systems, seeing them mature and eventually bring Terran R into space.

About the Role:

• Responsible for the thermal, structural, dynamic, and durability (fatigue/fracture) analyses on Aeon-R engines to guide design decisions and ensure reliability and performance requirements are met
• Responsible for the analysis of 3D-printed engine components, complex mechanical assemblies, and/or the structural integrity of the fully integrated engine assembly
• Work hand-in-hand with mechanical designers and manufacturing engineers to arrive at optimal solutions for the engine and vehicle programs
• Develop and execute tests to support development and qualification, including hands-on work like test article integration, instrumentation setup, and data processing

About You:

• Bachelor's degree in a science, engineering, technology, or mathematics field
• 12+ years of relevant analysis experience, preferably with complex engineering systems
• Experience with Finite Element Analysis
• Experience with computer aided design (CAD) software
• Experience through complete propulsion development lifecycle

Nice to haves, but not required:

• Detail-oriented, organized, and able to follow through
• Strong drive to deliver on ambitious schedules
• Experience with design of liquid propulsion components and systems
• Experience with Siemens NX, Teamcenter, and ANSYS workbench
• Familiarity with industry best practices
• Familiarity with aerospace standards
