About the role

Oversee the end-to-end manufacturing for the development and production of Combustion Device (fire-breathing) hardware for Aeon-R and Vacuum Engine programs.
Extensive experience authoring work instructions and/or process procedures to manufacture complex assemblies.

Our Terran R vehicle will deliver customer payloads to orbit, meeting the growing demand for launch capacity.
Here, you're not just executing tasks; you're solving problems that haven't been solved before, helping develop a rocket, a factory, and a business from the ground up.
Whether you're in propulsion, manufacturing, software, avionics, or a corporate function, you'll collaborate across teams, shape decisions, and see your work come to life in record time.
Closely collaborate with stakeholders within (machine shop, additive, etc.) and external to Manufacturing (Supply Chain, Propulsion Design, etc. ) to drive manufacturability and scalability in your hardware.
Ensure delivery to engine to meet program targets, as well as drive continuous improvement, new product development, and strategy for Combustion Device manufacturing at Relativity as a whole.
Experience interfacing with design engineering, manufacturing, and production personnel in a production environment.

Bachelor of Science degree in aerospace, mechanical, manufacturing engineering, or equivalent.
Minimum 2+ years of experience building and testing hardware in a manufacturing environment.
Experience in executing and driving projects in a fast-paced environment.
Ability to understand - and effectively advocate for
Develop initial processes required to build the hardware, implement into production, and drive process improvements to enable rapid production ramp.
Nice to haves but not required:
3+ years of experience building and testing hardware in a manufacturing environment.
Extensive experience with Combustion Device Design or Manufacturing.
