Description:

About the Team: The Engine Manufacturing team is dedicated to delivering high-performance engines and advancing innovative manufacturing systems that continuously improve cost, quality, and lead time.

You're not just executing on designs; you actively provide input that shapes new hardware iterations and regularly interface with engineers to make critical decisions for the Aeon R program.

Having successfully developed and refined processes for our initial development engines, the team is now focused on producing flight engines at rate for Terran R's aggressive launch manifest.

About the Role: As a Turbomachinery Engineer, you will produce components and assemblies for the fuel and oxidizer turbopumps of the Aeon-R and Aeon-R Vac engines.

As a Propulsion Manufacturing Engineer, you will own the manufacturing trades and then develop the processes for fabricating, testing, and delivering critical Aeon-R hardware and subassemblies.

You will serve as the main point-of-contact between the manufacturing and design teams as we optimize Aeon-R architecture and scale manufacturing operations.

To be successful in this role, you should be someone who thrives in ambiguity and is able to drive their own projects to completion.

You must have the passion, tenacity and resolve to work through challenging issues unique to rocket turbopumps and additively manufactured hardware.

We are looking for someone multifaceted, and capable of working at the interfaces of design, development, and analysis of turbomachinery.

Ideally, you are someone who has come from a fast paced, aerospace environment, having completed difficult projects while collaborating effectively with multidisciplinary groups.

About You: * Degree in engineering or related technical field and 2+ 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 but not required: * 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
