About the Team

The Propulsion Manufacturing Integrated Components team manufactures and tests critical Aeon-R engine components including manifolds, gimbal assemblies, brackets, orifices, and more. The team ensures on-time delivery of propulsion subassemblies to the Aeon-R engine program while driving continuous improvements in safety, quality, reliability, lead time, and cost. After delivering hardware for the first Aeon-R flight engines, the team is now ramping production while developing next-generation engines to make Terran R the most manufacturable high-performing rocket to date.

About the Role

• Own and develop manufacturing and test processes for 3D printed and machined Aeon-R engine components and subassemblies.
• Drive continuous improvements in manufacturability, assembly, and delivery of components, ensuring hardware meets all design requirements.
• Collaborate with manufacturing partners and technicians by writing work instructions, conducting root cause analysis, resolving issues, and tracking and reducing lead time.
• Partner with supply chain to develop and manage external supplier relationships, ensuring on-time hardware delivery.
• Work hands-on in a fast-paced, high-mix environment while collaborating cross-functionally and driving projects to completion.
• Build a strong manufacturing team and lead projects directly and cross-functionally.

Requirements

• Bachelor’s degree in engineering or related technical field and 5+ years of relevant experience in manufacturing engineering or a related role.
• Strong foundational knowledge of propulsion systems, mechanics of materials, and thermal-fluid systems to investigate and resolve hardware defects.
• Ability to work with and train technicians in a hands-on hardware environment, write work instructions and process plans for complex assemblies, and drive implementation of improvements and corrective actions.
• Vendor management experience including selection, defect disposition, and quality management.
• Proficiency with additive/subtractive manufacturing, precision inspection, GD&T (ASME Y14.5), and FEA using Ansys or similar tools.
• Experience with tooling design using Siemens NX or other CAD tools, including conceptualization, modeling, analysis, and fabrication.

Nice to Haves

• Experience in propulsion development programs.
• Experience transitioning products from development to high-volume production.
• Hands-on experience with CNC machining, welding, and high-pressure testing.
• Experience writing formal process specifications and manufacturing standards.
