Propulsion Engineer (Thermal & Fluid Analysis)
Hawthorne, CA
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.


As a propulsion engineer, you will make sure that fluid consumables are in the right place and at the right conditions throughout SpaceX's missions across all current and future vehicles and programs (Falcon, Crew Dragon, Starship, Starlink, etc.). You will make engineering decisions to improve vehicle performance and reliability.

  • Per-mission analysis on attitude control systems, propellant conditions, tank pressurization systems etc. to maximize performance while staying robust.
  • Automate workflow above to reduce engineering investment in per-mission analysis.
  • Pursue performance/robustness improvements.
  • Pursue operational simplicity and seek to reduce burden on other groups at SpaceX.
  • Produce quality documentation of your work to reduce miss-rate and improve efficiency.
  • Review peer work.
  • Bachelor's degree in an engineering discipline.
  • At least 1 year of experience using engineering simulation software such as MATLAB.
  • Master's degree in an engineering discipline.
  • 2+ years professional experience with thermal or fluid analysis.
  • Strong understanding of spacecraft and/or launch vehicle propulsion systems and fluid components.
  • Experience with 0-D and 1-D thermal/fluid networks.
  • Working knowledge of scripting languages.
  • Excellent oral and written communication skills.
  • Ability to deliver against an aggressive schedule.
  • Must be available to work extended hours and weekends as needed.
  • To conform to U.S. Government space technology export regulations, including the International Traffic in Arms Regulations (ITAR) you must be a U.S. citizen, lawful permanent resident of the U.S., protected individual as defined by 8 U.S.C. 1324b(a)(3), or eligible to obtain the required authorizations from the U.S. Department of State.
