Manufacturing Engineer, Chamber and Nozzle (Raptor)

SpaceX was founded under the belief that a future where humanity is out exploring the stars is fundamentally more exciting than one where we are not. Today SpaceX is actively developing the technologies to make this possible, with the ultimate goal of enabling human life on Mars.

MANUFACTURING  ENGINEER ,  CHAMBER AND NOZZLE (RAPTOR)  

SpaceX is seeking a manufacturing Engineer with deep expertise in CNC machining to create the Raptor engine’s combustion chamber and nozzle. These components feature some of the most complex geometries in rocket propulsion — including intricate regenerative cooling channels, thin-walled high-temperature alloys, and tight-tolerance surfaces that must survive extreme thermal and pressure cycles across hundreds of reuse cycles.  

You will design, implement, and scale CNC machining processes and programs that increase production throughput, improve dimensional accuracy and repeatability, and reduce cycle times while maintaining the extreme quality required for Starship. This role sits at the intersection of propulsion engineering, precision CNC machining, CAM programming, and data-driven manufacturing.  

Your work will directly enable rapid iteration and high-volume production of Raptor chambers and nozzles.  

RESPONSIBILITIES:

• Develop, deploy and iteratively improve CNC machining processes for Raptor combustion chambers and nozzles, including multi-axis milling, turning, and precision finishing of regenerative cooling channels.  

• Develop and optimize CNC programs, tool paths, and machining strategies for complex components using advanced CAM software and offline programming.  

• Implement closed-loop CNC process control with real-time monitoring of cutting forces, vibration, spindle load, temperature, and tool wear to maintain tight tolerances and prevent defects.  

• Integrate in-process metrology (touch probing, laser scanning, on-machine measurement) for adaptive CNC machining and automated quality verification within the same setup.  

• Build data pipelines that capture high-resolution CNC telemetry and feed statistical process control, predictive analytics, and machine learning models to minimize scrap and optimize parameters.  

• Design custom fixtures, workholding, and pallet systems that support high-precision CNC machining of large, thin-walled hardware while reducing setup time.  

• Own CNC software infrastructure including post-processors, macros, simulation, and digital twin integration, with version control and rigorous testing.  

• Collaborate with propulsion design, materials, and production teams to rapidly translate new chamber/nozzle designs into robust, repeatable CNC processes.  

• Drive continuous improvement initiatives to reduce cycle times, increase first-pass yield, and scale CNC capacity for high-rate Starship production.
