Senior Multiphysics Modeler
About The Position
Commonwealth Fusion Systems (CFS) is seeking a Senior Multiphysics Modeler to join their tritium program and process engineering team. This role will focus on developing a fuel cycle model for the ARC fusion power plant. The Senior Multiphysics Modeler will create simulation toolkits and workflows that integrate first-principles multiphysics simulations with industrial process models to support technology development and subsystem integration for key fuel cycle systems. The ideal candidate is an expert in heat and mass transport modeling, enjoys teaching, and building tools for others to use independently. This position requires a degree in a relevant engineering or science discipline, experience in process modeling and programming, a demonstrated ability to apply first principles to complex engineering problems, and experience conducting cost-benefit analyses. Success in multidisciplinary teams is also essential.
Requirements
- Master’s degree or similar experience with 7+ years in chemical engineering, mechanical engineering, physics, materials science, physical chemistry or similar
- 5+ years experience modeling process systems
- 5+ years experience in computer programming
- Knowledge of transport phenomena and chemical processes in gasses
- Experience building integrated process models
- Process engineering and systems integration
- Experience managing large data sets
- Understanding of scalable simulations
- Track record in version control
- Data reduction and results analysis
- Ability to occasionally lift up to 50 lbs
- Perform activities such as sitting, typing, standing, stooping, or climbing for extended periods of time
- Dedication to safety to mitigate industrial hazards that may include heat, cold, noise, fumes, strong magnets, lead (Pb), high voltage, and cryogenics
- Willingness to travel or work required nights/weekends/on-call occasionally
- Compliance with U.S. laws concerning the export of controlled or protected technologies or information
Nice To Haves
- Experience with Python and/or Matlab
- Experience with multiphysics tools such as Comsol
