Sr. Propulsion Engineer; Merlin Turbomachinery

Hawthorne, CA

Space

X 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 Space

X is actively developing the technologies to make this possible, with the ultimate goal of enabling human life on Mars.

As a Sr. Merlin Turbo machinery Engineer, you will own all aspects of ongoing Merlin Turbopump design, development, qualification, and production support. In this role, you will utilize your strong technical knowledge of turbo machinery as well as your ability to work with a wider team of specialists in the various pump sub systems to ensure maximum reliability of the Merlin engine. You will fully integrate with the Merlin development, refurb, and flight operations teams as we fly commercial, national security, and crewed missions.

• Support build, test, and flight of Merlin Turbopumps for Space
  
  X’s Falcon 9 and Falcon Heavy reusable launch vehicles
• Review and/or update detailed mechanical analysis on all the turbopump components/systems, and confirm that they meet the required standards for life and reliability targets
• Work with other engineers to ensure rotor dynamics/bearings and other mechanical elements (seals etc.) are correctly defined and implemented or perform analysis as needed
• Work with designers to support accurate and correct models and drawings for turbopump assembly and components, and ensure that these drawings are correct and able to be manufactured with the available processes (or develop process to enable them)
• Ensure that detailed layouts and stack-ups are up to date and ensure all the correct build clearances and fits are set such that the turbopump can be assembled and run correctly
• Work with manufacturing engineers and external suppliers to ensure Turbopump and key sub-assemblies are manufactured correctly and efficiently
• Work with teams developing other systems on the engine (combustion devices, valves, etc.) to ensure optimal Turbopump integration, and that risks are minimized across the engine
• Lead the resolution of issues encountered with the turbopump during testing or flight operations
• Support ongoing design, manufacturing or reliability improvements to Merlin turbo machinery
• Support M1D and MVacD engine test teams for development, qualification, and production engines
• Support launch and refurbishment teams on-site to ensure reliability during continued engine reuse

• Bachelor’s degree in an engineering discipline
• 5+ years of experience related to turbo machinery or rocket engine development

• Master’s degree in Mechanical or Aerospace Engineering
• Background in turbo machinery design (aero/hydro, CFD, stress analysis, HCF, LCF)
• Hands‑on experience with turbo machinery hardware build
• Experience with turbo machinery manufacturing and design of manufacturability
• Experience with turbo machinery testing and engine testing
• Understanding of thermodynamics, compressible and in compressible flow, thermochemistry mechanics and/or materials
• Professional experience using Siemens NX (Unigraphics) and ANSYS strongly preferred, Fluent or other comparable CFD package also desirable
• Understanding of engineering fundamentals and the ability to perform basic analysis
• Great attitude in the face of extreme technical and schedule challenges
• Experience at a nimble engineering organization or in a highly technical position that required a scrappy, entrepreneurial manner to accomplish tasks with tight time or budget constraints
• Full engineering lifecycle experience (design trade, CAD design, prototyping, manufacturing, testing, qualification, production, reuse)
• Demonstrated track record of excellent academic and professional achievement
• Excellent verbal and written communication skills, with both internal and external customers
• Ability to deliver against an aggressive schedule, without sacrificing safety or reliability

• Willingness to travel in support of testing (McGregor, TX), launching, and refurbishing (Cape Canaveral, FL and Vandenberg Space Force Base, CA) (~15% of year)
• Willingness to work extended hours and weekends as needed to resolve critical…
