Princeton University


The Princeton Plasma Physics Laboratory (PPPL) is a world-class fusion energy research laboratory managed by Princeton University for the U.S. Department of Energy’s Office of Science. PPPL is dedicated to developing the scientific and technological knowledge base for fusion energy. The Laboratory advances the fields of fusion energy and plasma physics research to develop the scientific understanding and key innovations needed to realize fusion as an energy source for the world.

We are seeking a Computational Scientist or Software Engineer to work on our TRANSP Development team to work on an exciting project developing tokamak simulators based on the equilibrium and transport solver TRANSP. TRANSP is used worldwide for the analysis and modeling of tokamak plasma discharges, for planning experimental campaigns, and for designing future fusion devices. This position will work on the modernization, modularization, and maintenance of the code base.


We are undertaking a major effort in expanding the physics scope of the code, as well as in the modernization and modularization of the code.

Areas of focus include:

  • multi-physics
  • multi-scale integration of physics phenomena
  • propagation of radiofrequency waves in plasmas
  • coupling between core and edge transport including non-axisymmetric effects
The candidate will contribute to the implementation of new physics modules and work with code developers to optimize existing modules. The candidate may also be involved in writing new modules to improve efficiency and compatibility with modern architectures.


Education and Experience:

  • PhD in Physics, Applied Mathematics or Computer Science with at least two years of relevant experience.
  • Master’s degree with at least five years relevant experience will be considered in lieu of a PhD
  • Background n plasma physics is highly desirable.
  • Must have programming experience in C/C++, CUDA and Python.
  • Hands-on working knowledge of the Git version-control system is highly preferred
  • Familiarity and understanding of Fortran would be greatly beneficial.
Knowledge, Skills and Abilities:

  • Applicants should have demonstrated experience working in a research-oriented environment
  • Technical knowledge of numerical analysis, parallel computing, and software development on Linux-based systems
  • Experience with large-scale scientific computing in plasma physics is highly desirable.
  • Must be team-oriented
  • Must have good verbal communication and interpersonal skills
  • Must demonstrate a willingness to learn.
The position and salary will be commensurate with the experience of the applicant. The work location is Princeton (NJ), but flexible work conditions can be considered.
