Senior Multiphysics Modeler

Commonwealth Fusion SystemsDevens, MA
$110,000 - $185,000Hybrid

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 be instrumental in developing a fuel cycle model for the world's first fusion power plant, ARC, located in Chesterfield County, Virginia. 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, with a drive to build and optimize devices. They should be adept at using non-dimensional analysis and rigorous integrated simulations, and enjoy teaching and building tools for others. Applicants need 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 multi-disciplinary 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

Nice To Haves

  • Experience with Python and/or Matlab
  • Experience with multiphysics tools such as Comsol
  • Exposure to process simulators like HYSYS
  • Use of engineering management tools
  • Confluence/JIRA and remote collaboration tools
  • Fusion energy experience
  • Chemical engineering
  • Atom and molecular mass transport

Responsibilities

  • Lead the development of an integrated power plant fuel cycle model
  • Develop models for unit operations and incorporate multi-effects in components
  • Develop simulation tools to enable targeted R&D for key fuel cycle technologies
  • Own the fuel cycle simulation tools and models
  • Validate models and identify key R&D requirements to enable validation where there are currently gaps in the literature
  • Collaborate cross-functionally with both internal and external experts to ensure fuel cycle models are feasible, economic and state-of-the-art
  • Develop processes and layouts for fueling subsystem blocks that are communicated through standard engineering documents
  • Generate detailed work plans and define milestones, integrated with R&D, to deliver validated models
  • Provide guidance to colleagues for use of developed modeling tools and outputs
  • Identify emerging trends and opportunities and influence CFSs’s fuel cycle modeling strategy
