Fluid Dynamics Engineer (m/f/d)

Mission Brief 

As part of the Launch Vehicle Loads and Dynamics team, you will work and contribute across the team’s broader aerodynamic, internal-fluid, and thermal analysis work. Your results feed loads definition, structural and flight dynamics as well as vehicle control and directly drive flight hardware design iterations. 

Your Role in Our Space Mission 

• Perform steady state and transient external aerodynamic and internal flow analyses using CFD and empirical/engineering methods across the full meshing / solution / post-processing workflow 
• Develop methodologies for assessing unsteady aerodynamic behavior (e.g. buffeting, separation, recirculation), characterizing the resulting buffet and aero-acoustic loads and delivering data for vibroacoustic, loads, and control analysis 
• Analysis of internal flow phenomena relevant to launch vehicle loads (e.g. propellant management, propellant sloshing, thermal stratification) using CFD and empirical/engineering methods 
• Support thermal coupled loads analysis of the launch vehicle and payload, maintenance of the launcher’s thermal models and thermal control system design by providing analysis 
• Develop and improve tools and automation for simulation, data processing, and analysis workflows 
• Contribute to the definition of test campaigns and flight instrumentation to validate and verify analysis models and requirements 

Qualification Checklist 

• Degree in the field of Aerospace of Mechanical Engineering, or similar 
• 3+ years of relevant experience in aerodynamics, fluid or thermal analysis in the field of aerospace or launch vehicles 
• Experience with CFD and fluid/thermal simulation tools (e.g. StarCCM+, Simcenter, Thermal Desktop/ESATAN/Thermica) 
• Proficiency in Python or MATLAB for automating pre- and post-processing workflows 
• Highly organized and proactive, with strong attention to detail 
• Ability to collaborate and communicate effectively in multi-disciplinary, cross-functional teams 
• Fluent in English 

Bonus Skills 

• Experience with launch vehicles aerodynamics or other unsteady aerodynamic environments (e.g. buffeting and transonic regime) 
• Experience with internal multiphase fluid dynamics on launch vehicles  
• Experience with thermal coupled load analysis of spacecrafts
