Simulation Engineer - #2634073

CFD Engineer (On-Site, Hamburg)

Help us push the limits of simulation.

FS Dynamics Hamburg is growing fast, tackling problems across multiphase & reacting flows, rarefied gases, plasma physics, FSI, and acoustics—often at micro-meter and milli-Kelvin scales. If you love turning hard physics into actionable engineering—and you’re the kind of person who won’t leave a stone unturned—you’ll feel at home here.

Why this role?

• Impact: Work on real-world challenges for leading European OEMs where your models influence design, yield, and time-to-market.

• Depth & variety: From CVD/etch surface chemistry to low-pressure plasma to micro-scale transport and thermal-structural coupling.

• Growth: Join one of Europe most active CAE hubs and collaborate with a 180+ CAE community across Germany, Sweden, Portugal, and Finland.

What you’ll do

• Build and validate computational models for fluid dynamics, heat-mass transfer, surface chemistry, particle physics and low-pressure/rarefied regimes.
• Run and refine simulations (STAR-CCM+ / COMSOL / ANSYS, etc.).
• Analyze results to uncover mechanisms and provide clear, decision-ready insights to customers and internal teams.
• Co-develop new multiphysics and methodology with our CFD & FEA & plasma groups (e.g., coupling, reduced-order/1D system models).
• Stay updated with advances in the physics modelling techniques and tools.

What you bring

• MSc or equivalent in Mechanical/Chemical Engineering, Computational Physics or related field.
• Strong foundation in fluid dynamics, heat & mass transfer, and ideally surface chemistry / reacting flows and multiphase flow.
• Hands-on with CFD tools (STAR-CCM+, Ansys, COMSOL or similar).
• Scripting/software skills (Python, MATLAB).
• A can-do, can-learn mindset, rigorous problem-solving abilities, and sharp attention to detail.
• Clear communicator and able to explain complex matters for broad audience.
• Comfortable working independently and in multidisciplinary teams.
• You are fluent in German and English, both written and spoken, and enjoy working in an international environment.

Nice to have

• Experience with 1D/system modeling (e.g., AMESim, Modelica).
• Experience with ML and AI tools like NVIDIA Physics NeMo.
• Knowledge and experience with Direct Simulation Monte Carlo or Lattice Boltzmann Method or Molecular Dynamics simulation.

What we offer

• Competitive salary.
• Training and development opportunities
• Flexible working time arrangements
• And other benefits.
