Fluid System Development Engineer

Fluid System Development Engineer

MaiaSpace

Paris, France

Job description

We are looking for a fluid system development engineer to join one of our agile multi-disciplinary teams in charge of the development of multiple propulsion systems on board the MaiaSpace launcher. This team develops advanced propulsion systems for the Colibri orbital vehicle and for the attitude control systems of the reusable first stage and the upper stage.

As part of the ACS and Kickstage Propulsion team, your main missions and responsibilities will consist of developing, modelling, testing and bringing to flight readiness complete fluid systems:

• Manage the specifications for propulsion fluid systems and their equipment, such as valves, tanks, pressure regulators and other fluidic components;
• Manage multiple key suppliers for propulsion sub-system equipment, which will involve multiple business trips both in France and in Europe;
• Conduct design and manufacturing activities for the propulsion fluid systems;
• Develop a performance and functional fluidic model in 0D/1D of the propulsion fluid systems;
• Consolidate the fluid systems budgets (pressure, mass flow, mass, etc.);
• Plan and conduct AIT activities for the propulsion fluid systems;
• Plan and execute multiple hot fire test campaigns for the propulsion fluid systems;
• Interact regularly with AIT and test teams in Vernon, involving a regular presence in Vernon;
• Prepare the flight submission documentation and be ready to participate to flight campaigns in Kourou;
• Participate to the definition of the operational modes and control algorithms for the propulsion fluid systems;
• Participate in the consolidation of vehicle and propulsion system budgets (propellants, power, performance, pressure, mass, length, data, etc.);
• Participate in the overall Colibri propulsion system definition and development;
• Participate in the Attitude Control Systems definition and development for all stages;
• Participate in the overall propulsion community of practice within MaiaSpace;
• Elaborate preliminary propulsion solutions for future IOS kick-stage versions.
