  Job Summary

  As we continue to push the boundaries of what's possible in innovative solutions for the building materials industry, we are currently in the exciting phase of building out a specialized team dedicated to advancing Asphalt Technology. If you are interested in groundbreaking work to build subject matter expertise (SME) around fundamental and formulation science in asphalt technologies OR expanding process capabilities to support key technology platforms, we invite you to join our R&D team in the Dallas Metro Area or Parsippany, NJ!

  
  Today, GAF R&D is looking for a computational scientist to develop and apply simulation methods for asphalt modification, transport and coating processes, including lab-scale and production-scale CFD (computational fluid dynamics) models. The ideal candidate will have experience with modeling newtonian and non-newtonian complex fluids as well as developing reduced-order models and digital twins based on those simulations. Activities will focus on the improvement and development of simulation methods, the experimental validation of those models and the optimization of equipment and processes to improve our roofing asphalt operations.
  
  Essential Duties

  Specific responsibilities include, but are not limited to:

  • Identifying problems that are uniquely suitable to be solved using a computational fluid dynamics (CFD) approach

  • Setting up, performing and analyzing computational fluid dynamics models for complex fluids and multi-component flow

  • Developing reduced-order models based on results from computational fluid dynamics simulations

  • Actively participating in project teams within R&D and operations

  • Writing project reports and presenting simulation results in internal meetings

  • Making simulation results available and usable by non-CFD experts

  
  Qualifications Required

  • MS Degree with a minimum of 2 years relevant experience OR PhD degree in a relevant field (e.g. chemical engineering, mechanical engineering, mathematics, physics, etc…)

  • Solid background in numerical methods and computational fluid dynamics of complex and/or multicomponent fluids

  • Experience using commercial or open-source CFD software (such as OpenFOAM, Ansys Fluent, etc,) as well as basic knowledge in programing languages (Python, C++)

  • Experience with the development and and experimental validation of simulation methods in an industrial setting

  • Experience working as part of a team and collaborating with experimental scientists to solve problems

  • Experience running simulations in Linux-based HPC clusters.

  
  Travel Requirements: up to 10%
