About the role

CFD Engineer (Delivery) role at PhysicsX, a physics AI company building a new simulation software stack. Based in London with 2-3 days/week in the central office; focus on delivering high-fidelity CAE simulations, expanding Singapore presence, and bridging CFD with data science and AI tools.

Responsibilities

  • Building models from geometry clean-up and meshing through to simulating and post-processing, for simple to moderately complex cases, with guidance from senior engineers on the more difficult aspects.
  • Adapting and using parametric CAD models (NX or CATIA), and contributing to simulation pipeline automation for design optimisation and DoE studies.
  • Supporting customer-facing work by helping prepare and present results clearly, under the direction of more senior team members, while building toward doing this independently.
  • Working at the intersection of CAE and Data Science to help generate simulation datasets for training Machine/Deep Learning models, and understanding data sampling impact on model accuracy and cost.
  • Using Flux (cloud platform) and on-premise HPC resources to run simulations, and learning smarter meshing and setup choices to improve performance.
  • Learning and applying engineering best practices, and helping adapt CFD model setups and outputs to support Deep Learning surrogate development.
  • Contributing to a culture of collaboration and shared learning within the Simulation Engineering guild, including onboarding newer engineers (at L2).
  • Occasional travel (Europe, Asia, Oceania) to support customer engagements, with increasing frequency as independence grows.

Qualifications

  • Growing foundation in fluid mechanics, heat transfer, and multiphase modelling.
  • Ability to apply core engineering principles to real-world problems under guidance from more senior colleagues.
  • Working knowledge of Star-CCM+, OpenFOAM, or Fluent; comfortable with built-in automation for scalable workflows.
  • Exposure to parametric CAD modelling (NX or CATIA) and coding in Python/Java (or ability to pick up quickly).
