The role

You will lead the end to end development of turbines for pump fed liquid propellant rocket engines. This includes conceptual sizing, detailed design, manufacturing, testing, and qualification.

What you will do

• Develop, maintain and improve reduced order design models for turbomachinery components.
• Lead conceptual design and architecture trade-offs for turbomachinery systems.
• Develop and maintain detailed three dimensional design workflows for turbine components.
• Perform aerodynamic analyses together with the CFD team.
• Work with the Engine Structures team on material selection for turbine rotors and stators.
• Own the technical development roadmap for hardware including design reviews and risk assessments.
• Plan, support and evaluate component and integrated engine level test campaigns.
• Work with multiple teams to deliver an integrated propulsion system.

Required qualifications

• MSc in aerospace engineering, mechanical engineering or a comparable technical discipline, or equivalent professional experience.
• 4+ years of professional experience in liquid rocket engine development, with significant responsibility for turbine development and testing.
• Hands-on experience in the design, analysis, development or testing of pump fed liquid propellant rocket engines.
• Excellent understanding of turbine aerodynamics, turbo pump power balance and architecture, thermo-mechanical design and material selection for rotating hardware.
• Working knowledge of seals, bearings and centrifugal pump operation across different turbo pump applications.
• Proficiency in Python, MATLAB or a comparable programming language.
• Proficiency in CAD and CFD software.
• Strong technical ownership, systems thinking and the ability to make sound engineering decisions with incomplete information.
• Fluent in English.
• Willingness to travel occasionally for test and launch operations.

Nice to have

• Siemens NX and StarCCM+
• Experience with transient cycle modelling: start up, shutdown, throttling and off nominal conditions.
• Experience taking an engine design from cycle definition and system-level trades into hardware and test.
• Experience analysing engine control, operability, stability, or failure cases.
• Planning and coordinating multidisciplinary engine development or test campaigns.
• Experience correlating models against hot fire test data.

Benefits

• Employee Participation Program: virtual company share program
• 30 days of vacation
• Company pension plan with 20% employer contribution after the probation period
• Subsidised lunch
• Fully financed Deutschlandticket
• Rental clothing with laundry service
