Fluid Engineer Intern (f/m/d)

Location Reims

Department Propulsion and fluid systems

Type Internship

Starting September 2026

The Fluids team at Latitude develops the fluidic ground-side and vehicle-side systems for the launch vehicle. Sub-disciplines within the team include valves, fluidic routing, pressure-control systems, and liquid level sensing systems among others.

These are precise systems posing difficult challenges to overcome, as they deal with the highest pressures and lowest temperatures seen on the entire vehicle. We are looking for motivated candidates that are self-driven and hands-on to join the team as an intern to help us solve these challenges.

In return, you will develop your technical skills and work alongside talented engineers that will be able to guide you toward the next step in your career, both technically and professionally.

Tasks & missions

The intern’s duties will include: Developing fluidic routing for the first and upper stages of the launch vehicle, including design, analysis, material selection, drafting, and assistance with manufacturing and testing. Write qualification and acceptance plans for vehicle valve components. Assist and, ultimately, lead the execution of these test plans, including pressure testing, cryogenic testing, and vibration testing. Design custom valves for the vehicle. This project will include the design of different types of valves (electromagnetic, pneumatic, etc.) for use in various rocket systems. The project involves a comprehensive approach to valve design, with a high degree of autonomy but under the supervision of experts in the field.
