Job Summary

We have an opening for a Modeling Physicist in the field of edge plasma physics for magnetic fusion energy devices.  You will apply expertise in numerical simulation to understand problems in edge fusion plasmas and plasma-surface interactions. The research aims to develop new edge transport and plasma-surface interaction models and simulations in support of experiments in the National Spherical Tokamak Experiment in Princeton Plasma Physics Laboratory Mega-Ampere Spherical Tokamak Upgrade in Culham Centre for Fusion Energy in Culham the UK the SPARC tokamak at Commonwealth Fusion Systems in Devens Massachusetts and in support of future lithium divertor concepts. This position is in the Spherical Tokamaks Group Fusion Energy Sciences Program of the Extreme Light Matter and Fusion Directorate.

The primary work location will be at Princeton Plasma Physics Laboratory in Princeton New Jersey.

In this role you will

  • Conduct research in edge plasma simulations analyze simulation results and provide physics understanding of results.
  • Conduct in-depth data analysis and compare simulation results across two-dimensional multi-fluid edge plasma codes to evaluate model behavior consistency and physical accuracy.
  • Work as a team member to guide and compare simulation and existing experimental data.
  • Collaborate in the development of new edge plasma physics and plasma-surface interaction models.
  • Document and publish research results in peer-reviewed scientific or technical journals and present results at external conferences seminars and/or technical meetings.
  • Pursue independent (but complementary) research interests and interact with a spectrum of scientists internally and externally.
  • Perform all assignments in accordance with ES&H security and business practice requirements and policies.
  • Perform other duties as assigned.

Qualifications :

  • PhD in plasma physics related technical discipline or the equivalent combination of education and relevant previous experience.
  • Advanced experience and knowledge in magnetic confinement fusion edge plasma physics and plasma-surface interaction physics.
  • Advanced experience and knowledge in numerical simulations and modeling methods.
  • Advanced experience and knowledge of magnetic confinement fusion plasma codes.
  • Advanced verbal and written communication skills necessary to work in a multidisciplinary team environment author technical and scientific reports and publications and deliver scientific presentations.
  • Experience working independently with minimal direction and effective interpersonal skills necessary to collaborate and work in a team environment.

Desired Qualifications

  • Experience with developing and implementing edge plasma physics models.
  • Experience with 2D edge plasma codes e.g. UEDGE SOLPS EDGE2D EMC EIRENE ERO.
  • Experience with data analysis tools and algorithms in Python Matlab or similar language.
  • Knowledge of tokamak operation and interpretation of experimental data.
  • Knowledge of edge plasma diagnostic techniques and atomic physics.

Pay Range

$175530 - $222564 Annually

This is the lowest to highest salary we would pay for this role at the time of this posting; pay will not be below any applicable local minimum wage.  An employees position within the salary range will be based on several factors including but not limited to specific competencies relevant education qualifications certifications experience skills seniority geographic location performance and business or organizational needs.
