PhysicsX Tech Stack

Physical AI software for simulation-driven engineering and manufacturing

Software Development London 201–500 employees Privately Held

PhysicsX builds AI software that replaces or accelerates physics simulation across the engineering lifecycle. Its stack pairs CFD and CAD tools (STAR-CCM+, OpenFOAM, Fluent, NX, CATIA) with PyTorch, TensorFlow and HPC schedulers (Slurm, LSF) on Kubernetes across AWS, GCP and Azure, a sign it trains large physics models on simulation data. Hiring is overwhelmingly senior engineering, with pains around mesh data loading and reliable ML deployment.
