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:

As an Engine Assembly Responsible Engineer on the Propulsion Integrated Design team, you will:

  • Own the overall layout and packaging of Aeon-R engines, in all of their different configurations (development, qualification, acceptance, first stage versus upper stage, etc.) 
  • Design and analyze final integration hardware, such as secondary structures, fluid manifolds, tubing, custom fittings, etc.
  • Work closely with component and sub-system owners across the Propulsion department to drive towards an optimal engine design.
  • Lead clean sheet conceptual design and layouts of new/upgraded engine configurations. 
  • Own and release top-level CAD models of the engine assembly. 
  • Track and report mass/mass projections of the Aeon-R engines. 
  • Own the Interface Control Diagram for Aeon-R engines, requiring close collaboration with vehicle and test stand partners. 
  • Champion configuration and change management for the Aeon-R engines. 
  • Partner closely with the Engine Integration engineers to successfully build and ship engines at increasing rate. 

About You:

  • Bachelor's degree in a science, engineering, technology, or mathematics field 
  • 8+ years of experience with fluid systems design and/or structural design
  • Experience applying fluid, thermal, structural, and mechanical design fundamentals
  • Experience with Computer Aided Design (CAD) software
  • Detail-oriented, organized, and able to follow through
  • Demonstrated drive to deliver on ambitious schedules, especially if unconventional & creative solutions are necessary to do so
  • Experience in mentoring junior engineers in the skills of design, layout trades, large assembly CAD ownership, change management, impact analysis, etc. 
  • Demonstrated project/technical leadership skills

Nice to haves, but not required:

  • Working knowledge of engine subsystems such as combustion devices, turbomachinery, valves, integration hardware, etc.
  • Experience in the design of liquid propulsion components and systems
  • Experience with large CAD model management, change management, and configuration management
  • Experience with Siemens NX, Teamcenter, and ANSYS workbench
  • Familiarity with industry best practices and aerospace standards
  • Familiarity with aerospace standards (AS, NAS, SAE, etc.)
