Über diese Computational Nuclear Engineer Stelle bei Thea Energy

Thea Energy · Vor Ort · Kearny, NJ
About Thea Energy:  
Thea Energy is leveraging recent breakthroughs in stellarator physics and engineering to create a faster and simpler approach to commercializing fusion energy. The company is reinventing the stellarator using computer-controlled arrays of planar coils thereby replacing the intricate, complex modular magnets required in all other stellarator architectures. Thea Energy is on a mission to create a limitless source of zero emission energy for a sustainable future.  
 
Position Overview:  
We are seeking a highly motivated Computational Nuclear Engineer to join our team, focusing on neutronics and multiphysics simulations for stellarator fusion systems. The ideal candidate will possess a strong background in computational transport methods, with a particular emphasis on multiphysics reactor design, dose rate calculations, and radiation shielding optimization. You will work with minimal supervision, contributing to cutting-edge research and development to ensure the safety and performance of Thea Energy’s stellarator systems.

Key Responsibility Areas:

  • Develop and implement advanced workflows for high-fidelity neutronics and related multiphysics simulations in complex 3D stellarator geometries.
  • Conduct simulations of fusion blanket performance, including tritium breeding ratios (TBR), energy deposition, material activation, radiation shielding, and more.
  • Collaborate with cross-disciplinary teams to perform multiphysics coupling (e.g., neutronics to thermal-hydraulics or structural analysis) to refine reactor designs.
  • Perform dose rate calculations and design optimized shielding solutions for personnel and sensitive equipment.
  • Prepare technical reports, presentations, and publications based on simulation results and optimization findings. 
  • Ideal Experience & Skillsets:

  • PhD in Nuclear Engineering, Computational Physics, Applied Physics, or a related field with 2+ years of experience; or a Master’s degree in a relevant field with 4+ years of experience.
  • Strong knowledge of Monte Carlo radiation transport codes (e.g., OpenMC, MCNP, Serpent).
  • Proficiency in programming languages commonly used in scientific computing, specifically Python and C++.
  • Proficiency in modern scientific software development best-practices (e.g. git, GitHub, CI)
  • Experience in multiphysics coupling frameworks (e.g., MOOSE, Cardinal, NekRS).
  • Excellent analytical, problem-solving, and communication skills.
  • Preferred Skills:
  • Experience with nuclear data processing and libraries (e.g., NJOY). Experience with deterministic neutron transport solvers (e.g. Atilla, OpenSN)
  • Familiarity with High-Performance Computing (HPC) environments and parallel programming (MPI/OpenMP).
  • Background in applying machine learning techniques to optimize nuclear simulation results or data handling.
  • Understanding of fusion-specific nuclear challenges, such as first-wall material damage and tritium fuel cycle management. 
  • Personal Attributes:
  • Ability to work independently and manage projects with minimal supervision in a startup environment.
  • Strong attention to detail and a passion for advancing the field of fusion energy research.
  • Willingness to collaborate with a diverse team of scientists and engineers within the company and externally.
  • Persistent optimism and a willingness to take on tough challenges.
  • Excited to think creatively about solutions to difficult problems and not relying solely on what has been done before. 
  • Company Benefits:

  • Salary range: $120,000-$180,000
  • Comprehensive health benefits (e.g. medical/dental/vision)  
  • Employee equity stock options  
  • 20 days PTO

  • It’s not necessary to meet all of the skillsets outlined above. Please feel free to send us a note and tell us why you would still be a great fit for this role or Thea Energy.  
      
    Diversity and Inclusion:  
    Thea Energy is an equal opportunity employer committed to creating a company of diverse backgrounds. By creating a diverse environment, we will bring new ideas and approaches to solving some of the world’s hardest (and most important) problems.
