👷 Build Engineer (Raptor Tooling)

All Space jobs

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 member of the Raptor tooling team, you will work with a team of elite engineers across multiple disciplines to design, build, and activate critical production assets required to build the next generation Raptor engine. As the first full-flow staged combustion rocket engine ever flown, Raptor has more than two times the thrust of our current Merlin engines that power the Falcon 9. Over 35 Raptor engines will power each fully re-useable Starship system, so this role is absolutely critical to ensuring the SpaceX produces enough engines for the fleet of Starships that will travel to the moon, Mars, and beyond.

This position is based at our production facility in Hawthorne, CA, but will involve work on designs and builds that are implemented across all of SpaceX’s sites supporting the Starship program.
