Job Description

• Perform CFD simulations for liquid rocket engines with a focus on hot gas flow and cooling channel analyses
• Analyze combustion flows, conjugated heat transfer (CHT), pressure losses, and flow instabilities
• Simulate regenerative cooling systems and assess thermal loads
• Support the design of combustion chambers, nozzles, and cooling structures through numerical analysis
• Couple CFD results with thermal and structural analyses
• Validate and calibrate CFD models using experimental and test data
• Conduct trade studies to optimize performance, efficiency, and thermal margins
• Work closely with design, systems, test, and manufacturing teams
• Document models, assumptions, results, and design recommendation

• Degree in Space Engineering, Aerospace Engineering (M.Sc.) or similar
• Minimum of 2 years of full-time experience
• Strong background in CFD, particularly for compressible flow, supersonic flow, hot gas flow conjugated heat transfer, cryogenic flow, reactive flows in rocket engines
• Profound understanding of fluid dynamics, thermodynamics, and heat transfer
• Profound understanding of cooling channel design
• Proactive thinking, high level of motivation, flexibility, and team-working skills
• Proficiency in both German and English
