About the role

CFD Engineer (Delivery) at PhysicsX in NYC, focusing on building and delivering high-fidelity CAE simulations integrated with AI/toward data-driven design. Opportunity to contribute from founding NYC team, with growth toward IC or Team Lead and occasional travel.

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 developing understanding of how data sampling choices affect model accuracy and cost.
  • Using Flux (cloud platform) and on-premise HPC resources to run simulations, and learning how to apply 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 of newer engineers (L2 tipping point).
  • Traveling occasionally (Europe, Asia, Oceania) to support customer engagements, with expectation to increase 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
  • Comfort using built-in automation features to support scalable workflows
  • Exposure to parametric CAD modelling (NX or CATIA)
  • Coding in Python/Java or demonstrated ability to pick up new tools quickly (advantage)
