Our mission is to unlock routine access to locations beyond Earth. To get there, we're building the vehicles for a space logistics network, refuelled in space rather than relying on Earth for every mission. We develop them in house, from the propellant and engines to the vehicles themselves.
Founded by engineers with 20+ years across Rocket Lab, MaiaSpace, and The Exploration Company, spanning engines, launch vehicles, and spacecraft.
Interns at P78 are embedded in the team and contributing to real projects from day one. You'll take ownership of a defined problem, work directly with the engineers building the hardware, and deliver something real. Background and institution matter less than attitude and ability. If you're curious, self-directed, and ready to learn quickly, we'd like to hear from you.
You'll work directly with the founders on the engine for P78's first vehicle 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.
We're looking for someone who builds. Someone who's done the analysis and the hardware, and knows why both matter.
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
- 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
- Rocketry, FSAE, engine builds or similar hands-on project work
- Engine or propulsion testing
- Test stands, instrumentation or data acquisition
- Machining, fabrication or workshop experience
