Description du poste

Overview

MaiaSpace is a European space tech company, designing, manufacturing and operating competitive and sustainable solutions for space mobility. We are driven by the belief that access to space is a major enabler for a better and more sustainable life on Earth, addressing the challenges faced by humanity: climate, resources, connectivity, and data. Our aim is to successfully design and test a cost-effective and reusable mini-launch vehicle by end of 2026.

The Colibri orbital vehicle has different roles. It will first play a kick-stage role enhancing MaiaSpace performance and injection flexibility. Then, in midterm horizon, additional functionalities will be added to the vehicle to address in orbit services opportunities from which active debris removal is one of our main targets. This vehicle is at the crossroad between a launcher and an orbital system.

Fluid System Development Engineer – Responsibilities

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.

Job Requirements / Qualifications

We are looking for candidates with the following experience and skills:

• Master’s degree in mechanical, aeronautics or space engineering (+5 years post-Baccalaureate).
• A minimum of 4 years of professional experience with direct involvement in propulsion system development (liquid or hybrid rocket engine systems) – both junior and senior profiles are encouraged to apply.
• Ability and practical experience using MATLAB, Simulink and Python coding is required.
• Ability to use fluidic 0D/1D modelling tools such as ECOSIMPRO or AMESIM is required.
• Ability to work as part of a team and flexibly with regard to a start-up environment.
• Autonomy, rigor, good interpersonal and communication skills, proactive problem-solving attitude.
• Ability to work quickly, be "solutions-oriented" and propose disruptive ideas.
• Ability and practical experience managing suppliers, specifying and purchasing hardware.
