Fluids Engineer (m/f/d)

Job description

Mission Brief As a Fluids Engineer in the Reusability Program, you analyse propellant behaviour across changing thermal conditions, transient operating states, and mission phases including ascent, shutdown, coast, reentry , and relight. Your work directly drives propellant management, pressurization, and feed system design for next ‑ generation reusable launch vehicles. Your Role in Our Space Mission - Define and analyse the overall propellant management architecture, including propellant location, acquisition strategy, residuals, depletion behaviour, and their interaction across mission phases - Analyse microgravity and low-acceleration propellant dynamics, including propellant surface behaviour modelled with VOF methods and coupled heat and mass transfer, to drive architectural choices - Derive tank pressurization concepts from mission requirements and reusability constraints, including transient behaviour across mission phases - Perform NPSP and inlet margin trades, including the influence of propellant thermal state and transient operating conditions on engine behaviour - Analyse propellant routing, including feedlines and valves, with focus on transients, operability, and reus...
