Propulsion Engineer (Merlin Hardware Development)

SpaceX•Hawthorne, CA

8d•$100,000 - $140,000•Onsite

About The Position

As a Merlin Propulsion Engineer, you will own engine hardware and software from first build through acceptance test, flight, and re-flight. You will drive design, process, and operational changes that improve Merlin reliability, producibility, and performance—and help Falcon scale production and flight rate without sacrificing the flight heritage that made it the world’s most reliable launch vehicle. On any given week you might be hands-on with the engine, in a design or test review, briefing a customer, or closing an anomaly investigation before the next launch.

Requirements

Bachelor’s degree in an engineering discipline or physics
1+ years of academic or professional hands-on experience performing fabrication, assembly, and/or testing
1+ years of academic or professional experience using CAD to design parts/assemblies

Nice To Haves

Master’s degree in mechanical engineering or aeronautical/astronautical engineering
1+ years of academic or professional experience related to combustion devices or rocket engine development
Strong foundation in fluid mechanics (compressible and incompressible), thermodynamics, combustion, structures/fracture mechanics, and materials—and the judgment to apply them to real hardware decisions.
Experience with manufacturing processes such as CNC mill/lathe, welding, castings, additive, etc. and proficient with the fundamentals of Design for Manufacturing/Assembly (DFMA)
Experience across the full engineering lifecycle—from design trade and CAD through manufacturing, test, qualification, production, and flight/operations.
Experience performing risk assessments or supporting timely closure of root-cause investigations
Analytical/scientific programming experience (Python, Matlab, etc.)
Experience using Siemens NX (Unigraphics) and ANSYS preferred, Fluent or other comparable CFD package also desirable
Comfortable briefing senior leadership and external customers on technical risk and hardware status
Ability to work well in a collaborative team environment including daily interactions with technicians, engineers, and managers
Excellent verbal and written communication skills, with both internal and external customers

Responsibilities

Serve as the Responsible Engineer for a Merlin engine component or system, where you will be the primary technical point of contact for your hardware through the complete life cycle
Lead Merlin development and qualification test campaigns for hardware improvements or root cause investigations
Design, analyze, produce, and operate Merlin propulsion hardware and systems across development and flight operations
Partner with engineers and technicians across production, test, launch, avionics, GNC (guidance, navigation & control), software, mission management, and flight reliability to deliver flight-ready engines
Resolve day-to-day production, test, and launch issues by getting hands-on with the hardware
Brief commercial and government customers on hardware changes and issues as a technical authority for mission success
Make sound, risk-informed decisions under time pressure, including during test and launch campaigns
Implement and maintain hardware and software verification and validation using automation and process controls that scale with flight rate
Develop and improve engine maintenance procedures with the launch site and test teams to improve hardware readiness and reduce turnaround time
Lead anomaly investigations related to your hardware, drive rapid resolution, and implement corrective actions to prevent recurrence
Build tools, especially while leveraging AI, to automate analysis, reduce repetitive work, and speed up engineering decisions
Run multiple concurrent projects, prioritizing against program milestones and business needs while maintaining excellent attention to detail
