• Validate simulation results by integrating experimental data and visualising outcomes for better design optimisation
• Optimise high-fidelity multiphysics simulations for complex applications using OpenFOAM and other computational frameworks
• Implement high-performance parallel computing (HPC) techniques to enhance simulation speed and efficiency
• Develop advanced numerical solvers and libraries to handle thermophysical properties of real fluids and multi-material systems
• Collaborate across disciplines, working with engineers, experimentalists, and computational scientists to refine and validate models
• Support machine learning (ML) applications by generating high-quality datasets for AI-driven analysis and digital twins
• Participate in agile development cycles, integrating SCRUM methodologies to improve workflow and project delivery
• Engage with stakeholders to align technical solutions with real-world industry challenges
• Present findings and technical advancements at industry conferences, workshops, and customer meetings

Essential Skills & Experience

• Extensive experience in OpenFOAM, including solver development and multiphase flow simulations
• Strong C++ programming skills, particularly in template meta-programming within OpenFOAM
• Expertise in high-performance computing (HPC) for parallelised CFD simulations
• Proficiency in geometric modelling, meshing, and visualisation tools for simulation pre- and post-processing
• Experience with multiphysics modelling, such as fluid-structure interaction, heat transfer, and electromagnetic fields
• Strong foundation in numerical methods, turbulence modelling, and fluid mechanics
• Ability to optimise computational efficiency and develop scalable solutions for complex simulations
• Experience working in a SCRUM environment, collaborating with multi-disciplinary teams

Desirable Skills

• Background in deep learning and AI-driven regression models for enhancing CFD predictions
• Experience with TensorFlow, PyTorch, or similar ML frameworks for managing large simulation datasets
• Prior exposure to HPC system administration and performance tuning
• Knowledge of multiphysics coupling techniques for integrating CFD with other domains such as electromagnetics or acoustics
• Experience in cross-industry applications of CFD, from industrial process modelling to medical and defence sectors

Benefits

• 25 days annual leave (+ bank holidays, with service-based increments)
• Flexible working arrangements, including hybrid/remote options
• Access to a state-of-the-art R&D environment with free on-site parking
• Contributory pension scheme and optional healthcare
• Cycle to Work Scheme
• Performance-based share options after three years
• Opportunities for team-building activities and professional development
