The Role
Perform fluids, CFD, and thermal analyses (steady and transient) to guide design and verification of rocket engine hardware across all flight phases. Validate models with test and flight data, collaborate with propulsion teams, improve system-level models and workflows, and support hardware development and safe operation.
Summary Generated by Built In

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.

 SR. PROPULSION FLUIDS ANALYST (RAPTOR SYSTEMS ENGINEERING) 

The Propulsion Fluids Analyst role is responsible for evaluating and improving engine hardware designs through fluids and thermal analyses using tools such as Sinda/Fluint, STAR-CCM+, and custom code to build, mesh, and solve models. You will analyze conditions across all operations—from startup through mainstage to shutdown—and for every phase of flight in the mission, while validating predictions with engine test and flight data. Your analytical conclusions will guide investigations spanning the entire engine, from individual valves and combustors to coupled system-level interactions, directly enabling the development, production, and safe operation of the most advanced, full-flow staged combustion engine boosting the largest launch vehicle in history. 

RESPONSIBILITIES:

  • Perform fluids, CFD, and thermal analysis to drive design decisions for flight engine hardware and provide verification that reliability and performance requirements are met for all phases of flight of the mission
  • Collaborate with propulsion engineers on various engine teams to proactively anticipate and drive analyses throughout engine component design cycles.
  • Ground model predictions in reality through hands-on validation of testing development and flight hardware
  • Organize and improve integrated system models and analysis workflow for greater output and efficiency

BASIC QUALIFICATIONS:

  • Bachelor’s degree in an engineering discipline
  • 5+ years of professional experience in fluids, CFD, and thermal analysis

PREFERRED SKILLS AND EXPERIENCE:

  • Master’s degree in an engineering discipline
  • Demonstrable proficiency in the basic principles of compressible and incompressible fluid mechanics and thermodynamics
  • Experience with setup, execution, de-bugging, and post-processing (geometry, mesh generation, and model selection) of steady-state and transient CFD simulations using ideal and real-fluid equations of state (using StarCCM+, ANSYS CFX, or other)
  • Experience with creating watertight parasolids for CFD using Siemens NX
  • Experience with conjugate heat transfer simulations
  • Experience with transient fluids modeling (using SINDA/FLUINT or other)
  • Experience with thermal and heat transfer modeling (using ANSYS or other)
  • Experience in using thermal and fluids hand-calcs to validate or improve confidence in higher fidelity models
  • Strong fundamental understanding of engine cycles and injector types used in liquid bipropellant rocket engines
  • Proficiency in MATLAB, Python, etc. to automate/script tasks and post-process data
  • Previous experience in the aerospace industry
  • Demonstrated ability to execute high quality work in a technical environment on tight timelines and aggressive schedules
  • Demonstrated ability to provide and concisely communicate (oral and written) highly technical information to a broad audience
  • Self-motivated to solve complex problems
  • Eager to participate in the extremely challenging but high impact environment that is SpaceX

ADDITIONAL REQUIREMENTS:

  • Willing to work extended hours and weekends as needed

COMPENSATION AND BENEFITS:

Pay range:

Propulsion Engineer/Senior: $135,000 - $190,000.00/per year

Your actual level and base salary will be determined on a case-by-case basis and may vary based on the following considerations: job-related knowledge and skills, education, and experience.

What We Do

SpaceX designs, manufactures and launches the world’s most advanced rockets and spacecraft. The company was founded in 2002 by Elon Musk to revolutionize space transportation, with the ultimate goal of making life multiplanetary. SpaceX has gained worldwide attention for a series of historic milestones. It is the only private company ever to return a spacecraft from low-Earth orbit, which it first accomplished in December 2010. The company made history again in May 2012 when its Dragon spacecraft attached to the International Space Station, exchanged cargo payloads, and returned safely to Earth — a technically challenging feat previously accomplished only by governments. Since then Dragon has delivered cargo to and from the space station multiple times, providing regular cargo resupply missions for NASA.
