Propulsion Fluids Analyst (Raptor Systems Engineering)

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. 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.

: Willing to work extended hours and weekends as needed

QUALIFICATIONS

: Bachelor’s degree in an engineering discipline 1+ years of 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.
