Materials Engineering 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 support P78's propellant and materials research programme — characterising hydrogen peroxide-based propellant systems, developing passivation processes, and running material compatibility testing. You'll work directly with the founders at an early stage, with real ownership of your work 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
  • Material compatibility testing: immersion, gravimetric analysis, mechanical property assessment
  • Passivation process development for H₂O₂-compatible system components
  • Propellant handling and characterisation under supervised laboratory conditions
  • Supporting data analysis and experimental documentation
What we're looking for
  • Background in chemistry, materials science, chemical engineering, or similar
  • Comfortable in a lab environment — hands-on, methodical, safety-conscious
  • Exposure to energetic materials, propellants, or corrosive fluid handling is a plus
  • Self-directed and able to operate with limited supervision
