Propellant Chemistry Intern

6-month end-of-study internship · France · March 2027

Why P78

P78 is building the propulsion systems and orbital vehicles that connect every asset in space — from Earth orbit to the lunar surface. 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.

About the role

You'll synthesise the hypergolic fuel P78 uses for hot-fire testing. This is hands-on synthetic chemistry work — designing and executing a synthesis route, producing fuel to a quality standard suitable for propulsion testing, and working safely with reactive materials. You'll work directly with the founders from day one.

This is an end-of-study internship with a view to a permanent role for the right person.

What you'd work on
  • Synthesis and production of hypergolic fuel for hot-fire test campaigns
  • Developing and documenting synthesis routes and quality procedures
  • Characterisation and purity validation of produced batches
  • Safe handling and storage of reactive and energetic materials
What we're looking for
  • Background in organic or synthetic chemistry
  • Comfortable running independent lab work — you design the route, you execute it
  • Experience with reactive or energetic materials is a plus
  • Methodical, safety-conscious, and self-directed
