The Fluid Department is responsible for the development of the launcher’s onboard fluid systems, as well as the fluid systems for ground and test facilities.

The Fluid Department is especially responsible for:

• Designing fluid systems according to functional needs, system architecture, and the choice of fluids for all company fluid systems: launcher, ground, and test facilities.
• Selecting the appropriate components to perform the required functions.
• Modelling the behavior of the system to validate the design.
• Defining how the system needs to be operated.
• Ensuring the safety and reliability of the designed system.
• Analyzing test results to make sure the system responds as designed.
• Optimizing built systems to improve reliability and efficiency.

Responsabilities

As a Fluids Engineer, you will participate in several missions involving the simulation, testing and integration of ground and onboard equipment.

To test all engine elements, several test benches will be integrated by the end of the year. Then, the two stages will also need to be integrated and tested. Test results will need to be analyzed in order to assess the system response under real conditions.

Main missions

• Take responsibility for critical hardware for space operations or ground support

• Design and develop fluid and mechanical systems intended for ground support or the launch vehicle

• Ensure full ownership of the hardware, from architecture, design and analysis, through to integration, testing and launch

• Manage production and procurement processes related to fluid systems

• Apply your overall technical knowledge to perform fluidic and structural sizing, routing and design, while taking cost and schedule constraints into account
