  • Ensuring high-quality and robust implementation of core CFD solver components in Simcenter STAR-CCM+
  • Supporting maintenance of our existing capability (bug fixing, code refactoring, etc.)
  • Design and development of new features based on requests from both product management and internal strategic initiatives
  • Participating in regularly scheduled team meetings and contributing ideas to drive innovation in our technology
  • Supporting other developers through design discussion and code review 

Required Knowledge/Skills, Education, and Experience:

  • A Master’s or PhD degree in engineering or physical science discipline, ideally focusing on novel schemes for fast simulation
  • 2 years’ experience in commercial CFD software development, or 5 years’ experience in non-commercial CFD software development
  • Expertise in implementing numerical methods for solution of the Navier-Stokes equations
  • Expertise in numerical modeling of aerodynamic and hydrodynamic applications
  • Expertise in object-oriented C++ software development
  • Expertise in high-fidelity and high-performance parallel CFD algorithms on heterogeneous architectures, including GPUs
  • Expertise in development of complex software applications using modern design patterns and principles 

Preferred Knowledge/Skills, Education, and Experience:

In addition, preference will be given to candidates with the following skills and experience: 

  • Expertise in areas of physical science: thermodynamics, heat transfer, multiphase, or combustion
  • Expertise in application of CFD methods: vehicle aerodynamics, internal combustion engines, turbomachinery
  • Experience with Java programming
  • Experience in multi-team, collaborative software development including source control and collaborative design and code reviews
