Great people

to build a great

launcher

The Fluid & Propulsion Systems Department is responsible for the development of the launcher’s main engines, auxiliary propulsion, onboard fluid systems, as well as ground and test facilities fluid systems.

Within this department, the Fluid Systems team specifically focuses on:

• Designing fluid systems based on functional needs, system architecture, and fluid selection for all company fluid systems (launcher, ground, and test facilities).
• Choosing the appropriate components to meet the functional requirements.
• Modeling system behavior to validate design choices.
• Defining operation procedures for the fluid systems.
• Ensuring safety and reliability across all designed systems.
• Analyzing test results to verify system behavior and performance.
• Optimizing existing systems to improve reliability and efficiency.

As a Group Lead – Fluid System Engineer, you will play a dual role, combining technical expertise and managerial leadership. While actively contributing to the design and development of the launcher’s fluid systems, you will also be responsible for leading and structuring a team of 8 full-time engineers, ensuring efficient project execution, resource management, and talent development.

Technical leadership and coordination

• Oversee the design, development, and optimization of fluid systems for the launcher, ground, and test facilities.
• Ensure that system functional needs, architecture, fluid selection, and component choices align with performance, reliability, and safety requirements.
• Guide the team in system modeling, test analysis, and optimization to improve efficiency and robustness.
• Ensure smooth coordination with other engineering teams, integrating fluid systems within the overall vehicle architecture.
• Contribute to strategic planning and technical roadmaps, in collaboration with the Department Head.

Team management

• Lead, support, and mentor a team of engineers and interns, fostering a collaborative and high-performance environment. Promote a culture of knowledge sharing, technical efficiency and continuous improvement.
• Define human and budgetary resource needs, in alignment with the Team Lead and company priorities.
• Conduct performance reviews, goal setting, and career development discussions, in coordination with HR.
• Support the team’s skills development by identifying relevant training opportunities.
• Oversee team well-being and engagement, including team-building initiatives and fostering a positive work environment.

• Bachelor’s or Master’s degree in mechanical, aerospace, chemical, or energy engineering (or equivalent).
• 5+ years of relevant experience in the aerospace, chemical, or energy industry (or similar), including experience in a leadership or coordination role.
• Strong expertise in fluid mechanics, thermodynamics, and system modeling.
• Knowledge of valves, pressure regulators, and industrial piping is a plus.
• Hands-on experience with modeling software (EcoSim), CAD tools (NX, Catia), CFD tools (Fluent, Star CCM+), and programming languages (Python, Matlab, Fortran) is highly appreciated.
• Strong team leadership, mentoring, and interpersonal skills.
• Excellent communication skills and ability to work cross-functionally.
• Fluent in English (French is a plus).

As part of the Electronic and Software Systems department of the company, you will be part of the GNC team which missions are:

• Guarantee the performance of the system by technically defining it, specifying the materials to be supplied and the tests to be conducted,
• Carry out dimensioning studies of the components of the flight GNC chain (sensors, actuators, computer),
• Carry out design studies of flight control algorithms (analysis of piloting strategies, verification of the feasibility of a mission with respect to this strategy, algorithmic design)

• Development of the command allocation algorithms for Zephyr.
• Development of the FDIR (Fault Detection, Isolation and Recovery) algorithms using non-convex optimization, etc…
• Validation and qualification on the GNC flight simulator

During this internship, you will gain practical experience with:

• Using Matlab Simulink for GNC development in aerospace applications
• Multi-disciplinary optimization techniques
• Systems modeling and state-space representation
• Command and control engineering principles for dynamic systems

As a Safety Engineering Intern, you will join the Safety & Regulatory team, and your tasks will include several activities within the following areas:

Risk and Hazard Analysis

• Perform detailed risk assessments using methodologies such as Failure Modes and Effects Analysis (FMEA), Hazard and Operability Studies (HAZOP), and Fault Tree Analysis (FTA).
• Identify potential system hazards, failure modes, and their causes and consequences, and propose mitigation strategies to reduce or eliminate identified risks

Development and Implementation of Safety Plans

• Assist in creating and refining safety plans for new and existing products, ensuring alignment with relevant industry safety standards.
• Define safety goals, allocate safety requirements to system components, and support their validation.

Safety Testing and Validation

• Participate in designing and executing safety validation tests, both in controlled environments (e.g., lab simulations) and in operational settings.
• Analyze test results to verify the effectiveness of safety measures and ensure compliance with safety standards.
• Support root cause analysis in case of test failures and suggest improvements.

Cross-Functional Collaboration

• Work closely with engineering teams (mechanical, software, electrical, testing, etc.) to ensure safety requirements are integrated intothe design process.
• Liaise with quality assurance and production teams to implement safety improvements during manufacturing.
• Support the safety team in interfacing with customers and regulatory bodies (during project reviews and safety audits, preparation of safety reports and technical documentation).
