This includes ground equipment, such as test stands for research & development, qualification and acceptance testing of propulsion systems and rocket stages, as well as entire launchpads. Close cooperation with other departments such as Propulsion Technology and Launch Vehicle is necessary since their requirements dictate the design of the ground support equipment. As a Fluid Systems Engineer, you take on a coordinative role, owning an engineering module/system, having the complete lifecycle in mind. You make sure that the design approaches applied are consistent across multiple projects while synergies are exploited to build reliable and safe systems, according to specification. You are responsible for the delivery of the systems according to specification and work closely together with design engineers to reach this goal efficiently. Your Role in Our Space Mission: Reporting directly to the Manager Ground Fluid Systems, the engineer's tasks are focused on but not necessarily limited to: - Own engineering modules/systems within larger projects, including status reporting, issue escalation, and proactive management of requirements with stakeholders across multiple (sub)systems. - Identifying problems and risks in the project realisation and escalating them properly. - Coordinate, plan, drive design and commissioning activities with design engineers. - Develop and update harmonized design approaches and incorporate lessons learned into processes and project delivery. Ensure compliance with regulatory and harmonized internal standards through design reviews. - Support procurement and delivery of systems/services with process plant engineering, ensuring specifications are met. - Contribute to design reviews which are in the field of expertise, keeping adjacent topics in mind. - Provide technical guidance to junior engineers and advise on rocket propulsion aspects of test and launch facility design.
