Molecular and Fluid Dynamics Engineer

Overview

Join FS Dynamics Hamburg as a Simulation Engineer specializing in Molecular and Fluid Dynamics. This role offers a unique opportunity to connect molecular science with industrial-scale engineering simulations in a technically challenging environment, working on advanced multiphysics workflows involving CFD and Molecular Dynamics.

Key Responsibilities

• Design, implement, and validate sophisticated CFD and Molecular Dynamics simulation processes for industrial applications.
• Translate fundamental molecular mechanisms and chemical interactions into practical and efficient modelling strategies across scales.
• Critically review academic research and modeling techniques to adapt proven methods into robust, manufacturable workflows.
• Simulate complex systems featuring heat and mass transfer, multiphase and reacting flows, particle transport, surface chemistry, and molecular transport phenomena.
• Utilize MD platforms like LAMMPS or GROMACS and integrate their insights with continuum-scale CFD models using tools such as STAR-CCM+, ANSYS Fluent/CFX, COMSOL, or OpenFOAM.
• Analyze simulation outputs to discern key physical and chemical mechanisms, quantify uncertainties, and provide clear engineering recommendations.
• Balance in-depth scientific modeling with practical industrial application to optimize solution complexity and reliability.
• Collaborate with experts in CFD, FEA, plasma, and system simulations to develop coupled multiphysics workflows and reusable methodologies.

Qualifications and Skills

• Master's degree or Ph.D. in Chemical Engineering, Mechanical Engineering, Computational Physics, Materials Science, Applied Physics, or related fields.
• Comprehensive knowledge of transport phenomena, fluid dynamics, heat and mass transfer, thermodynamics, statistical mechanics, and numerical modeling.
• Proven experience with Molecular Dynamics simulation software such as LAMMPS, GROMACS, NAMD, or OpenMM.
• Proficiency in industrial CFD software including STAR-CCM+, ANSYS Fluent/CFX, COMSOL Multiphysics, or OpenFOAM.
• Capability to scrutinize academic studies and implement effective modeling approaches for industrial use.
• Hands-on work with multiphase flows, reacting flows, diffusion, adsorption, surface chemistry, rarefied gases, and particle-laden flows.
• Programming or scripting experience in Python, MATLAB, C++, or related languages to automate workflows and enhance simulations.
• Excellent analytical and problem-solving skills, with a pragmatic approach focused on industrial relevance.
• Strong communication skills in English; German language skills highly advantageous for customer relations and DACH region integration.

Preferred but Not Required

• Experience with surface chemistry, plasma interactions, chemical vapor deposition, etching, semiconductor processes, catalysis, membranes, porous media, or electrochemical systems.
• Knowledge of DSMC, LBM, rarefied gas dynamics, kinetic theory, multiscale or reduced-order modeling, and AI/ML applied to engineering workflows.
• Background in consultancy, industrial research and development, OEM collaboration, or customer-facing technical projects.

What We Provide

• Engagement in complex, technically sophisticated projects with direct industrial relevance.
• Opportunity to influence advanced CFD, Molecular Dynamics, and multi-scale simulation techniques within a fast-growing Hamburg team.
• Access to a broad European expert network spanning over 180 CAE professionals across multiple countries.
• Close collaboration with specialists across CFD, FEA, plasma, system simulations, and multiphysics domains.
• Competitive salary package, focused professional development, flexible working arrangements, and other company benefits.
• An international and dynamic engineering atmosphere with ample chances for technical and career growth.
