Propulsion Development Engineer (m/f/d)

At Rocket Factory Augsburg (RFA) , we have one clear goal: to create low-cost, flexible, and reliable access to space. We specialize in building small launch vehicles designed to deploy satellites into Low Earth Orbit (LEO) and beyond. Together with you, we aim to revolutionize space services and help improve life on Earth. Sounds interesting? Then join our journey and become part of the team driving the New Space movement in Europe.

Our international and agile team is looking for support from a motivated person to own the design and development of engine propellant inlet lines and associated hardware ensuring correct integration with other subsystems. If you want to see your designs fly, work side-by-side with passionate engineers, and take full ownership of your hardware.

Your Tasks

• Support the development of liquid rocket engine feed lines based on real test data and development roadmap
• Collaborate daily with Test, Manufacturing, analysis and Production teams
• Investigate test anomalies and perform root cause analysis to improve performances
• Ensure design documentation is correct and up to date
• Understand the basics of turbomachinery, valve, thrust chamber and injector design
• Use various testing, analysis, modelling and simulation tools to estimate or calculate system performance
• Interpret simulation results and incorporate learnings into CAD (Thermal, Structural, Flow, etc.)
• Perform design, analysis and development engineering tasks for various propulsion systems
• Create test plans and analyse test results
• Initiate and foster production of engines
• Creation of medium to long term timelines for development of the engine’s subsystems

Your Qualifications

• Degree in Aerospace Engineering, Engineering or related discipline
• 2+ years work experience in space propulsion systems
