Computational Plasma Physicist – Transport Modeling

Location: Kearny, New Jersey, United States; on-site

Salary: $100,000–$140,000 per year

Company

hirify.global is developing commercial fusion energy through stellarator designs that use computer-controlled arrays of planar coils.

What you will do

• Run and analyze integrated modeling simulations for the Eos and Helios stellarators.
• Apply gyrokinetic, fluid, and reduced transport solvers to project confinement, heat, particle, and momentum transport.
• Maintain and extend gyrokinetic and transport modeling frameworks.
• Build reproducible simulation pipelines and data analysis tools for the design-to-validation workflow.
• Use turbulence and transport analysis to guide equilibrium and coil optimization.
• Collaborate with physics and engineering teams to develop operational scenarios and interpret hardware results.

Requirements

• PhD in Plasma Physics, Computational Physics, Applied Mathematics, or a related field; a master’s degree with 3+ years of direct transport or turbulence modeling experience may be considered.
• Strong understanding of gyrokinetic theory and transport processes.
• Experience developing scientific simulation codes in Python, C++, or Fortran.
• Experience with Linux-based HPC environments, code scalability, and performance optimization.
• Ability to manage complex projects from theory through implementation with minimal supervision.
• Rigorous approach to code verification and physics validation.

Nice to have

• Experience with core or edge gyrokinetic codes such as GENE, stella, CGYRO, GX, GENE-X, XGC, or Gkeyll.
• Experience with stellarator equilibrium and stability codes including VMEC, STELLOPT, DESC, or TERPSICHORE.
• Familiarity with advanced numerical methods, GPU programming, or surrogate and reduced models.
• Peer-reviewed publications and experience presenting complex physics to multidisciplinary engineering teams.

Culture & Benefits

• Collaborative, fast-paced startup environment focused on fusion energy.
• Comprehensive medical, dental, and vision benefits.
• Employee equity stock options.
• 20 days of paid time off.
