Turbopump Turbine Engineer (Aerospace)

Location: Parsdorf, Bavaria, Germany

Company

hirify.global develops sustainable launch systems for small and medium-sized satellites and constellations serving Low Earth Orbit.

What you will do

• Lead the end-to-end development of turbines for pump-fed liquid-propellant rocket engines, from conceptual sizing and architecture trades through manufacturing, testing, and qualification.
• Develop reduced-order turbomachinery models for engine cycle analysis and maintain three-dimensional turbine design workflows.
• Perform turbine aerodynamic analyses with the CFD team and support material selection and thermomechanical design for high-temperature, high-pressure rotating hardware.
• Own the technical development roadmap, including design reviews, risk assessments, manufacturing follow-up, and qualification planning.
• Plan, support, and evaluate component and integrated engine test campaigns, including instrumentation, test predictions, data review, and model correlation.
• Collaborate with Cycle, Turbomachinery, Valves, Feed Systems, Controls, Structures, Thermal, Manufacturing, and Test teams.

Requirements

• MSc in aerospace engineering, mechanical engineering, or a comparable technical discipline, or equivalent professional experience.
• Several years of liquid rocket engine development experience with significant responsibility for turbine development and testing.
• Hands-on experience designing, analysing, developing, or testing pump-fed liquid-propellant rocket engines.
• Strong knowledge of turbine aerodynamics, turbopump power balance and architecture, thermomechanical design, material selection, seals, bearings, and centrifugal pump operation.
• Proficiency in Python, MATLAB, or a comparable programming language, plus CAD and CFD software; Siemens NX and StarCCM+ are preferred.
• Fluent English required; occasional travel for test and launch operations is expected.

Nice to have

• Experience with transient cycle modelling, including start-up, shutdown, throttling, and off-nominal conditions.
• Experience taking engine designs from cycle definition and system-level trades into hardware and testing.
• Experience with engine control, operability, stability, failure-case analysis, multidisciplinary development, or test campaign coordination.
• Experience correlating models against hot-fire test data.

Culture & Benefits

• Virtual company share program.
• 30 days of vacation and a company pension plan with a 20% employer contribution after the probation period.
• Subsidised lunches and a fully financed Deutschlandticket.
• Rental workwear with laundry service and sponsored sports club membership.
