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.


The Propulsion Components team develops the most advanced spacecraft and launch vehicle components in the world. Our engineers serve as hardware experts for the flow and position control devices that drive the critical capabilities on the Starship/Super Heavy Vehicle- from regulators and butterfly valves to flap actuators.  We design, develop and characterize components for simplicity, manufacturability and reliability in extreme environments, with temperatures ranging from 80 to 800 K, and pressures beyond 800 bar. As a Propulsion Components Engineer at SpaceX, you will have the opportunity to utilize your knowledge, experience, and creativity to develop novel solutions at the cutting edge of space technology. You will own the relationship between our vehicle hardware/systems teams and manufacturing teams while spearheading your own projects, utilizing your skills in analysis, development testing, and mechanical design. You will provide input into vehicle architecture trades and take a lead role in design and flight readiness on Starship, the vehicle that will make humanity multi-planetary.


  • Develop state-of-the-art, manufacturable flow control devices (valves, regulators, solenoids) and mechanisms (flap/fin/payload door actuators) across Starship and Super Heavy stage systems. Question requirements, delete parts and processes, simplify/optimize, accelerate, and automate component deliveries.
  • Partner with manufacturing, production, testing, and supply chain to achieve SpaceX’s highest-yet component build rate, striving for high factory yield and automotive volume/cost. Accelerate component delivery to >1 full stacked launch vehicle per month.
  • Generate and maintain detailed drawings, component specifications, analysis and risk assessments.
  • Spearhead root cause investigations that arise in development, production, test, integration and launch, implement corrective actions to prevent repeat failures.
  • Set the standard for rigorous component design and qualification testing, increasing scrutiny as the vehicle matures in pursuit of commercial and crewed orbital missions.
  • Target zero in-flight anomalies of propulsion components. Reduce component-caused production and launch delays, and minimize containments.
  • Act as the chief engineer, collaborating with stage/component teams to arrive at the simplest solution for the vehicle. Inform system-level architecture, with component capabilities and vulnerabilities in mind, to minimize cost of payload to orbit.


  • Bachelor’s degree  in an engineering discipline or physics.
  • 5+ years of experience designing and analyzing mechanical systems. 


  • Strong interpersonal and collaborative skills, enthusiasm for problem solving, and desire to optimize modern rocket production and launch processes.
  • Master's degree or 8+ years of professional experience in mechanical or aerospace engineering.
  • Experience designing, building, testing and troubleshooting mechanical systems.
  • Strong project management skills and effective communication of technical concepts across multi-disciplinary teams.
  • Hands-on experience with fluid, gas, or high voltage systems.
  • Leadership experience on a project or research team.
  • Experience using test instrumentation and control components (e.g. pressure transducers, thermocouples, resistance temperature detectors, relays, solenoid valves, etc.).
  • Knowledge of electro-mechanical devices, gear trains, actuators, motors, valves, regulators, or other fluid and position control devices.
  • Understanding of fundamental principals in fluid systems and solid mechanics.


  • Travel to vendors and other SpaceX sites as needed. 
  • Ability to pass Air Force background check for Cape Canaveral.
  • Able to work flexible hours and occasional weekend support 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.

Voluntary Self-Identification

For government reporting purposes, we ask candidates to respond to the below self-identification survey. Completion of the form is entirely voluntary. Whatever your decision, it will not be considered in the hiring process or thereafter. Any information that you do provide will be recorded and maintained in a confidential file.

As set forth in SpaceX’s Equal Employment Opportunity policy, we do not discriminate on the basis of any protected group status under any applicable law.

Race & Ethnicity Definitions

If you believe you belong to any of the categories of protected veterans listed below, please indicate by making the appropriate selection. As a government contractor subject to the Vietnam Era Veterans Readjustment Assistance Act (VEVRAA), we request this information in order to measure the effectiveness of the outreach and positive recruitment efforts we undertake pursuant to VEVRAA. Classification of protected categories is as follows:

A "disabled veteran" is one of the following: a veteran of the U.S. military, ground, naval or air service who is entitled to compensation (or who but for the receipt of military retired pay would be entitled to compensation) under laws administered by the Secretary of Veterans Affairs; or a person who was discharged or released from active duty because of a service-connected disability.

A "recently separated veteran" means any veteran during the three-year period beginning on the date of such veteran's discharge or release from active duty in the U.S. military, ground, naval, or air service.

An "active duty wartime or campaign badge veteran" means a veteran who served on active duty in the U.S. military, ground, naval or air service during a war, or in a campaign or expedition for which a campaign badge has been authorized under the laws administered by the Department of Defense.

An "Armed forces service medal veteran" means a veteran who, while serving on active duty in the U.S. military, ground, naval or air service, participated in a United States military operation for which an Armed Forces service medal was awarded pursuant to Executive Order 12985.

Voluntary Self-Identification of Disability

Why are you being asked to complete this form?

We are a federal contractor or subcontractor required by law to provide equal employment opportunity to qualified people with disabilities. We are also required to measure our progress toward having at least 7% of our workforce be individuals with disabilities. To do this, we must ask applicants and employees if they have a disability or have ever had a disability. Because a person may become disabled at any time, we ask all of our employees to update their information at least every five years.

Identifying yourself as an individual with a disability is voluntary, and we hope that you will choose to do so. Your answer will be maintained confidentially and not be seen by selecting officials or anyone else involved in making personnel decisions. Completing the form will not negatively impact you in any way, regardless of whether you have self-identified in the past. For more information about this form or the equal employment obligations of federal contractors under Section 503 of the Rehabilitation Act, visit the U.S. Department of Labor’s Office of Federal Contract Compliance Programs (OFCCP) website at
