About the role

Simulation-focused engineering role at Freeform to develop physics-based, data-driven models for a production-scale metal 3D printing factory; requires strong multi-physics background and ability to build models from scratch in an interdisciplinary, fast-moving environment.

Responsibilities

  • Develop high-performance numerical solvers for simulating the physics of advanced metal 3D printing systems
  • Implement numerical simulation models for real-time or near-real-time performance on HPC or GPU platforms
  • Work with software engineers to build and deploy physics-based and data-driven models of the laser powder bed fusion process
  • Work with software engineers to integrate low-level solvers into simulation pipelines and interface with hardware systems
  • Guide the integration of computational geometry and meshing techniques to support large-scale, physics-driven simulations
  • Architect simulation modules for execution on specialized compute hardware including FPGAs and GPUs
  • Contribute to the development of model-predictive control strategies alongside control engineers
  • Generate and maintain documentation for all algorithms, solvers, and integrated system

Qualifications

  • Bachelor’s degree in applied mathematics, physics, computer science, mechanical engineering, or a related technical field
  • 10+ years of professional experience developing custom simulation solvers with a PhD in one of the above fields
  • Demonstrated experience writing low-level numerical solvers for physical simulations
  • Strong programming skills in C, C++, or CUDA
  • Experience developing simulations in a high-performance compute environment (i.e. running on GPUs)
  • Academic or professional familiarity with solid mechanics, continuum mechanics, or other physical modeling domains
