P78 is building the propulsion systems and orbital vehicles that connect every asset in space, from Earth orbit to the lunar surface. We're looking for someone who builds. Someone who's done the analysis and the hardware, and knows why both matter.
Founded by engineers with 20+ years across Rocket Lab, MaiaSpace, and The Exploration Company, spanning engines, launch vehicles, and spacecraft.
You'll work directly with the founders on P78's first propulsion system and the facility that fires it. This is one of the rare internships where you're in from a clean sheet: engine design, building the test stand that qualifies it, and running the first hotfire campaigns. You'll own a real problem end to end and deliver something that runs. Background and institution matter less than attitude and ability.
End-of-study internship, with a path to a permanent role for the right person.
- Engine design and analysis, alongside the founders and other industry leaders
- Test facility build, from layout and propellant lines to instrumentation and data acquisition
- Hotfire campaigns, from setup and running through analysis and iteration
- Safety systems and operating procedures for live propellant and hotfire ops
- Strong mechanical or aerospace fundamentals, with real engineering judgment
- Hardware you've personally built and tested. Machined, assembled, wired, fired, and fixed when it broke. Rocketry, FSAE, engine builds
- As competent designing and analysing, as building and testing
- Self-directed, taking a problem from start to finish
- Fluent English; working French a strong plus
