Key Responsibilities
- 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.
Required Qualifications
- 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.
- Proven engineering excellence, strong problem-solving abilities, and a passion for rocket propulsion and space.
- Strong communication and organisational skills, with the ability to manage competing priorities effectively.
- Ability to work both independently and within multidisciplinary teams.
Bonus Skills
- Proficiency in EcosimPro/ESPSS for fluid system simulation and analysis.
- Hands-on testing experience with fluid systems, including cryogenic fluids and oxygen compatibility.
