Job Summary:

General Atomics (GA), and its affiliated companies, is one of the world’s leading resources for high-technology systems development ranging from the nuclear fuel cycle to remotely piloted aircraft, airborne sensors, and advanced electric, electronic, wireless and laser technologies.

We recognize and appreciate the value and contributions of individuals with diverse backgrounds and experiences and welcome all qualified individuals to apply.

The DIII-D National Fusion Facility in Torrey Pines, CA is the U.S.’s principal magnetically confined fusion research facility, focusing on the exciting science of the burning plasma state and its control in preparation for ITER, and developing the path to self-driven fully non-inductive operation for future fusion reactors. It has a strong focus on underlying science, and the application of this to improve fusion performance.

Maintaining high performance while eliminating transients such as Edge Localized Modes (ELMs) and disruptions represents a challenging and rich area of magnetically confined fusion physics. We are looking for a talented scientist to explore the physics of plasma stability and understand the interactions of 3D fields and other effects in controlling core instabilities and ELMs.

Work will involve experiments, analysis, simulation and participation in diagnostic and hardware initiatives on DIII-D and other international facilities via collaboration.


  • Conduct research to develop insights into plasma stability and the response of tokamak plasmas to 3D fields, used to probe or directly control instabilities. A particular focus will include the application of 3D fields to control edge localized modes. Other foci include tearing mode physics and plasma braking effects.

  • A strong engagement with a proposed new coil array and associated power supplies is expected, and will provide a basis for innovation in the above fields.

  • Jobholder should also, play a substantive role in development of effective fusion scenarios for future devices including ITER, working with scenario development teams and implementing/understanding stability control issues.

  • Work will involve conducting experiments, executing analysis, and running simulation codes.

  • Work may also involve development, implementation or support for diagnostics or other facility hardware systems.

  • Principle work will be on the DIII-D facility, but work may also entail short engagements at international facilities such as MAST-U, ASDEX Upgrade, EAST or KSTAR.

  • As they become experienced, the jobholder will be expected to identify ideas and needs for future research, and should have aptitude in this direction.

  • Publication of work through scientific journal papers represents a primary deliverable, as well presentations at international conferences.

  • Participation in experimental operation and support of DIII-D and other tokamaks worldwide.

  • Performs other duties as assigned or required.

Job Qualifications:

  • Typically requires a Bachelors degree, Masters degree or PhD in scientific or related technical field and progressively complex scientific experience as follows; four or more years experience with a Bachelors degree and two or more years experience with a Masters degree. Equivalent scientific experience may be substituted in lieu of education.

  • Must have; (1) a thorough understanding of relevant scientific concepts, principles, and theory, particularly with regard to general tokamak plasma behavior; (2) experience demonstrating a broad application of those concepts; and, (3) experience working with tokamaks including control approaches to achieve physics goals; (4) rigorous understanding and demonstrated experience in tokamak MHD equilibrium and stability physics.

  • Must possess the ability to; (1) understand new concepts quickly; (2) apply them accurately throughout an evolving environment; (3) organize, schedule, and coordinate work phases; and, (4) determine the appropriate approach at the task level or, with assistance, at the project level to provide solutions to a range of complex problems.

  • Must have strong communication, computer, documentation, presentation, and interpersonal skills, ability to work independently and as part of a team; able to perform complex tasks in one scientific area; and, lead a team of less experienced professional employees on semi-routine tasks.

  • Facility in moving rapidly from one task area to another, and ability to work extended hours and travel as required.

  • Ability to communicate effectively with the scientific and engineering communities of DIII-D and collaborators, including written and oral technical presentations.
