About Stellarex Energy
At Stellarex Energy, we are building foundational technology for the clean energy transition by harnessing stellarator fusion to provide safe, reliable, and carbon-free baseload power. Turning this ambitious physics and engineering goal into industrial reality requires an exceptional, mission-driven team. If you are ready to solve one of humanity's greatest technological challenges and build transformative hardware from the ground up, we invite you to join our team in the Greater Toronto Area.
Role Overview
Stellarex Energy is seeking an outstanding, highly technical Plasma Physicist to drive the physics design and optimization of our prototype stellarator facility in the Greater Toronto Area. Reporting to the technical leadership of the project, you will serve as a technical specialist in optimizing 3D magnetic field geometry to achieve superior plasma confinement. In this key role, you will integrate advanced numerical modeling and theoretical physics across plasma shaping, fast particle/alpha confinement, turbulent transport reduction, energy confinement scaling, and high-beta equilibrium, bridging fundamental physics calculations directly into engineering coil design baselines.
Core Responsibilities
· Magnetic Geometry Optimization: Drive the multi-variable optimization of 3D non-axisymmetric magnetic field configurations to maximize plasma performance, stability, and operational margins.
· Fast Particle & Alpha Confinement: Execute physics modeling and codes to minimize energetic ion/alpha particle losses, ensuring neoclassical transport optimization and robust heat load management.
· Turbulence & Transport Control: Analyze micro-instabilities, gyrokinetic turbulence, and turbulent transport reduction strategies to enhance global energy confinement times.
· High-Beta Stability & Equilibrium: Evaluate 3D MHD equilibrium, finite-beta stability limits, and magnetic island divertor topologies to support stable, high-density plasma operations.
· Engineering Physics Integration: Translate optimized magnetic flux surfaces and boundary conditions into actionable engineering requirements for high-field superconducting magnet coil designers.
Required Qualifications & Experience
· Education: Ph.D. in Plasma Physics, Nuclear Engineering, Applied Physics, or a closely related computational field.
· Experience: 5+ years of post-doctoral or senior research experience executing computational plasma physics and magnetic confinement optimization programs.
· Stellarator Physics Expertise: Deep technical mastery in 3D magnetic equilibrium (e.g., VMEC), neoclassical transport (e.g., STELLOPT, ROSE, NEO), gyrokinetics, or fast ion orbit dynamics.
· Computational & Codes Mastery: Proven track record developing, modifying, or deploying physics simulation codes, multi-objective optimization algorithms, and magnetics modeling tools.
· Cross-Functional Leadership: Demonstrated ability to collaborate seamlessly with magnet engineering teams, and communicate complex physics baselines to technical leadership.
Compensation & Benefits
Stellarex offers an industry-leading competitive base salary paired with meaningful company equity options, providing direct ownership in our long-term enterprise growth. We also offer comprehensive health and dental coverage, professional development support, and relocation assistance to the Greater Toronto Area.
