Senior Engine Cycle Engineer (m/f/d)

The role

You will own the engine cycle and top level technical architecture of a pump fed liquid rocket engine. You will translate mission and vehicle needs into an integrated engine design and manage technical budgets and roadmaps.

What you will do

• Build, maintain and validate engine cycle models across nominal, throttled and off nominal operating conditions
• Lead cycle trade studies and sensitivity analyses
• Perform top level engine sizing and define principal operating points and component interface conditions
• Drive architecture and design trade offs across various engine subsystems
• Own the top level engine requirements, assumptions, interface definitions and technical budgets
• Act as the technical decision driver for cross functional design issues
• Own the technical development roadmap and timeline
• Coordinate technical reviews and give recommendations to Propulsion leadership and programme teams

Required qualifications

• MSc in aerospace engineering, mechanical engineering or a comparable technical discipline, or equivalent professional experience
• Several years in liquid rocket engine development, with real responsibility for engine cycle analysis, engine architecture or propulsion system integration
• Hands on experience with high pressure, pump fed liquid rocket engine cycles: designing, analysing, developing or testing them
• Excellent understanding of engine cycles, thermodynamics, fluid dynamics and turbomachinery power balance
• Steady state cycle modelling, top level engine sizing and performance prediction
• Experience planning and coordinating multidisciplinary engine development or test campaigns, and driving a technical roadmap to agreed timelines
• Proficiency in Python, MATLAB or a comparable programming language
• Strong technical ownership and systems thinking
• Fluent in English
• Willingness to travel occasionally for test and launch operations

Nice to have

• 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
• Enough breadth across valves, feed systems, ignition, controls, structures and thermal management to arbitrate trade offs
• 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
• Rental clothing with laundry service
• Sport Clubs membership (EGYM Wellpass)
• Individual learning allowance granted after the probation period
• Childcare allowance
• Flexible mobility budget: Deutschlandticket, JobRad bicycle leasing, FINN JobAuto, or a fuel allowance
