About the position

The engine manufacturing department's mission is to produce high performing products & manufacturing systems by continuously innovating on cost, quality, and lead time. Through cross-functional collaboration, high levels of accountability, and a focus on safety we support the Terran R program. We are responsible for providing design feedback on new hardware iterations, developing new manufacturing methods and systems, and ultimately building engine and vehicle hardware for testing prior to our first launch. Our team's highlights from the last 6 months include the MDC of the first Aeon-R engine, completing thousands of hours of PBF printing, building and testing over 50 valves of 26 different iterations, and implementing large scale process improvements along the way.

Responsibilities

  • Produce components and assemblies for the fuel and oxidizer turbopumps of the Aeon-R and Aeon-R Vac engines.
  • Own the manufacturing trades and develop the processes for fabricating, testing, and delivering critical Aeon-R hardware and subassemblies.
  • Serve as the main point-of-contact between the manufacturing and design teams to optimize Aeon-R architecture and scale manufacturing operations.
  • Drive projects to completion in a fast-paced environment, addressing challenging issues unique to rocket turbopumps and additively manufactured hardware.

Requirements

  • Degree in engineering or related technical field and 12+ years of relevant experience.
  • Experience with turbopump assembly procedures, including rotor balancing, interference fits, clearance checks, structural proofing, and leak checks.
  • Manufacturing Process Experience: Fluids Testing, Machining, Additive.
  • Knowledge of general assembly and test procedures, including tolerance stack-up analysis, structural proof testing, and pressurized leak checks.
  • Experience with Siemens NX or other CAD and analysis tools.
  • Experience with Tooling design, including conceptualization, modeling and drafting, and detailed analysis.

Nice-to-haves

  • Experience working with additively manufactured engine hardware.
  • Experience with GD&T (ASME Y14.5) and industry specifications.
  • Experience in a startup or agile development environment.
  • Experience working in a flight development program.
