Location: Munich, France
Workplace: Onsite
Employment Type: Full time
Job Function: Administration & Executive Assistance
Seniority: Mid level

Key Responsibilities

  • •Perform CFD simulations of propulsion components (valves, regulators, orifices, injectors, feed lines) to characterize internal flow, pressure drop, and flow-induced loads.
  • •Support design trade studies across steady-state and transient operating envelopes, including resolving flow anomalies such as cavitation, choking, and flow separation.
  • •Model thruster plume characterization from near-field continuum expansion to far-field rarefied flow, accounting for relevant gas dynamics effects and plume-induced impacts (thermal/contamination/force-torque).
  • •Translate CFD results into actionable design inputs by collaborating with propulsion design engineers and structural and thermal analysts, and communicate findings to multidisciplinary teams.
  • •Validate and correlate CFD models against test data (cold-flow, hot-fire, plume diagnostics), maintain simulation workflows and meshing practices, and produce technical reports supporting design reviews and certification.
Travel: Low travel

Pay and Benefits

Salary: EUR 50,000 - 70,000 annually

Key Requirements

  • •M.S. or Ph.D. in aerospace (or related field) with 3+ years of hands-on CFD experience relevant to propulsion or fluid dynamics.
  • •Proficiency with CFD software such as ANSYS Fluent, STAR-CCM+, OpenFOAM, or equivalent.
  • •Experience modeling compressible, multiphase, and/or rarefied gas flows relevant to propulsion valves and thruster plumes.
  • •Familiarity with plume characterization methods such as DSMC or continuum-rarefied coupling is a strong plus.
  • •Strong grounding in fluid mechanics, thermodynamics, and gas dynamics fundamentals, including correlating CFD predictions against test data.
