Job description

About the Team:

The Propulsion team at Relativity is focused on developing and delivering highly performant and manufacturable engines for Terran R. Engineers are responsible for the entire lifecycle of their parts, from initial design through production to qualification and flight. The team fosters a culture of bottoms-up decision-making, free from technical gatekeeping, where ownership and accountability are key at all levels. But designing engines with a quarter million pounds of thrust is just the beginning. As the flight configuration enters qualification, the team is now exploring modifications for future engines, including thrust upgrades, new cycles, and design for mass production.

About the Role

You will lead a team of analysts that is responsible for the analysis of integrated design hardware, which consists of things like the Aeon R engine's gimbal, bellows, flex hoses, propellant ducts, manifolds, primary structure, secondary structure, tubing, etc. Additionally, your team will own generating interface loads via engine assembly FEA models that drive the sizing of hardware across the entire engine. You will also be a key voice in conversations pertaining to best practices for analysis approaches, acceptable design factors, material allowables, etc. This role will require managing a small team, requiring strong mentorship, project management, establishing priorities, communicating with leadership, providing technical guidance, and recruiting. Close collaboration with stakeholders within Propulsion Engineering (Combustion Devices, Turbomachinery, and Components) and external to Propulsion Engineering (Materials, Design Criteria) is essential. To be successful in this role, you should be someone who thrives in ambiguity and knows how to lead (and guide) projects to completion. 

You and your team will be:

  • Responsible for the thermal, structural, dynamic, and durability (fatigue/fracture) analyses on Aeon-R engines and subsystems, 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
  • 5+ years of relevant analysis experience, preferably with complex engineering systems
  • Experience in mentoring and demonstrated leadership skills
  • Experience with Finite Element Analysis Experience with computer aided design (CAD) software
  • Detail-oriented, organized, and able to follow through Strong drive to deliver on ambitious schedule

Nice to haves, but not required:

  • Experience in leading high performing teams 
  • 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
