CFD Engineer - AI-Driven CAE & Marine Hydrodynamics

PhysicsX; Singapore; On-site; SGD 70,000 - 110,000; Full time

Job summary

PhysicsX is seeking a CFD Engineer (Delivery) to join our Singapore team at the founding stage. You will build CAE models integrated into AI-enabled workflows and work directly with customers on-site to solve engineering challenges across multiple industries.

You'll contribute to high-fidelity simulations using OpenFOAM/OpenFOAM-family tools, develop automation for scalable workflows, and collaborate with data science and ML engineers to generate catalytic simulation datasets.

Qualifications

• Growing foundation in fluid mechanics, heat transfer and multiphase modelling.
• Working knowledge of CAE tools such as OpenFOAM, Star-CCM+ or Fluent.
• Exposure to parametric CAD modelling (NX or CATIA).
• Coding in Python/Java - or ability to pick up new tools quickly - is an advantage.
• Experience in a commercial, non-research environment is preferred.
• Ability to set up CFD simulations for moderately complex cases with guidance.

Responsibilities

• Define and solve engineering challenges with Data Scientists and ML Engineers.
• Build and run high-fidelity simulations (OpenFOAM/Star-CCM+/Fluent); interpret results.
