Company Details

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.

Work with brilliant, passionate engineers to tackle difficult problems and push the boundaries of rocketry. This team will engineer the rocket engines that will take humankind to Mars.


  • Work with development turbomachinery engineers using requirements for a new propulsion system or component to convert those requirements into one or more 3-dimensional concepts, using NX, in the form of a mechanical layout for review
  • Consult with manufacturing engineers, thermal and structural analysts, development engineers, materials and process engineers and other product team members to refine the concept into a viable prototype to be further pursued for testing, development, qualification and flight
  • Use ANSYS to conduct basic finite element analysis to iterate the concept until it reaches a level of maturity where it can be studied by the propulsion analysis group for final, comprehensive analysis as defined by the project objectives
  • Take a general conceptual layout of a turbomachine or component device and break it down into detail parts that balance requirement for operability, reliability, cost, weight, producibility and several other criteria
  • Build up and own turbomachine tolerance stackup, incorporating information from operational simulations to understand critical interface clearances and inform manufacturing and assembly choices
  • Generate detail part production drawings fully dimensioned with GD&T verified to meet functional requirements by use of tolerance stackups
  • Interface with vendor or in-house fabrication and assembly teams during design and prototype hardware builds. Incorporate any produciblity lessons learned by design change and drawing revision
  • Support development testing efforts by incorporating design changes if necessary to further improve hardware performance or reliability
  • Provide ongoing technical support to production effort with engineering change orders to make design changes that improve producibility or reliability
  • Responsible for configuration management at the system or subsystem level using Teamcenter
  • Results will meet requirements, applicable specifications and be manufacturable


  • Bachelor’s degree in an engineering discipline
  • 3+ years of experience using CAD to design parts/assemblies
  • Experience working with fluid systems


  • 5+ years of professional  3D CAD design experience
  • 5+ years of professional finite element analysis (FEA) experience
  • Ability to design parts, tooling and test fixtures necessary to build rocket engine hardware
  • Familiar with high strength, oxidation resistant, propellant compatible materials for use in cryogenic and high temperature environments
  • Familiar with manufacturing capabilities (typical tolerances) and processes: turning, milling, drilling, reaming, EDM, grinding, brazing, welding, 3D printing
  • Familiar with mechanical seals (metallic and elastomeric o-rings) and threaded fasteners
  • Understanding of high pressure fluid tubing systems and typical fittings for aerospace hardware and applicable standards
  • Basic understanding of NDT techniques and how to design hardware for ease of inspection
  • Fundamental understanding and ability to implement GD&T
  • Ability to do hand calcs to roughly size structural elements of a design
  • Familiarity and/or experience with turbomachinery
  • Ability to pre-size components using finite element modeling
  • Extensive knowledge of propulsion engine systems and components
  • Proficiency with NX, Teamcenter and ANSYS


  • Willingness to travel in support of launching and testing of hardware


  • 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.
