Fluid Systems Engineer, Propulsion (m/f/d)

Mission Brief

As a Fluid Systems Engineer, you will develop, analyse, and validate the fluid systems that power and support our launch vehicle propulsion architecture. Working across the entire development lifecycle, you will transform requirements into robust hardware and system solutions, from concept and modelling through testing, qualification, and flight operations support.

Your Role in Our Space Mission:

• Define fluid system requirements, architectures, and interfaces in collaboration with cross-functional engineering teams.
• Develop and maintain analytical and simulation models to evaluate fluid system performance and operability.
• Design fluid system hardware and assemblies, including the creation of technical drawings and manufacturing documentation.
• Support component procurement, manufacturing, integration, and troubleshooting activities.
• Plan, execute, and evaluate component- and system-level test campaigns.
• Analyse test data, identify root causes of anomalies, and drive design improvements.
• Generate technical reports, specifications, and verification documentation.
• Ensure fluid system performance, reliability, and safety throughout the full product lifecycle.

Qualification Checklist

• M.Sc. or M.Eng. in Aerospace Engineering, Mechanical Engineering, or a related field.
• Strong fundamentals and practical experience in fluid dynamics, including the modelling and analysis of complex fluid systems, ideally in the context of rocket propulsion.
• Hands-on experience in test preparation, operation, and post-test data analysis and review.
• Experience with machining processes, drawing creation, and CAD software, preferably SolidWorks or Siemens NX.
• Proficiency in Python or similar programming languages for engineering applications and automation.
• Skilled in data analysis and the preparation of technical reports and engineering documentation.
