Job description

If you are searching for the best new ideas and share our vision, join us as a Computational Physicist- MHD Reconstruction. This is what you need to know:

Location: Knoxville TN, Madison WI or Vancouver BC

Salary: Highly Competitive Plus Benefits

Contract: Permanent, full time

Reporting to: VP Stellarator Optimization

Your role in the mission:

We are seeking a Computational Physicist to develop and advance an integrated, multi‑fidelity MHD–Edge–Divertor modeling framework that supports optimization, stability analysis, equilibrium reconstruction, synthetic diagnostics, and real‑time plasma control. The successful candidate will contribute to the development of high‑performance simulation tools and predictive modeling capabilities that enable deeper understanding of stellarator plasma behavior and inform key engineering and physics decisions.

This role is critical to the success of our Infinity Two stellarator technology, with direct impact on system design, operational control strategies, and scenario development. Working at the intersection of computational physics, plasma science, and fusion engineering, the individual will help shape the performance and evolution of both Infinity One and Infinity Two programs, accelerating the path toward commercially viable fusion energy.

This role delivers the core physics‑based modeling and control capability enabling between-shot analysis, real‑time plasma optimization, AI‑enhanced physics validation, and integrated design of diagnostics and control systems for next‑generation stellarators.

Responsibilities

Critical Priority (Infinity Two)– Real‑Time Equilibrium Reconstruction

• Develop andreal‑time 3‑D equilibrium reconstructionsolution for stellarator plasmas.

• Integrate accelerated equilibrium solvers with diagnostics, actuators, and control systems.

• Support MHD and divertor heat‑flux and particle control.

• Provide input for high fidelity models for physics validation.

Physics‑Informed & Proxy Models

• Work with engineering and physics to createhigh‑quality accelerated (proxy) modelsfor:

• Core MHD + edge/divertor coupling

• Heat and particle flux (SOL, divertor, pumping)

• Neutron fluence

• Energetic particles

• Combined MHD and neoclassical bootstrap current

Synthetic Diagnostics, Hardware & Controls

• Implementsynthetic diagnostics(magnetics, spectroscopy, bolometry, pressure, fueling, input power, neutron diagnostics) with support from engineers and diagnosticians.

• Support diagnostic and control system design, including magnetic sensors, spectroscopy and fluctuation diagnostics.

• Work withCODAC to define data structures and access for real‑time and offline analysis.

What you’ll need:

• Familiarity with equilibrium reconstruction tools for magnetic fusion. Familiarity with existing reconstruction tools for stellarators is highly desired.

• Working in a shared development workspace: Git, github, gitlab, or some other file management system

• Numerical modeling with one or more of the following: Python, C/C++, Fortran

• Familiarity with *nix, High-Performance and/or GPU computing: Bash, Slurm, MPI, OpenMP, JAX, Cuda

• Familiarity with real‑time control systems for fusion devices.

• Handling large data sets. Working with engineers to reduce data set sizes.

• Generating reports and shared documents with Microsoft Office products (Word, Excel, PowerPoint) and various online collaborative tools (Confluence.

We offer

In addition to a basic salary and yearly bonus, you will also get…

• A hybrid work policy
• Stock options
• Relocation allowance
• Insurance plans
• Retirement options
• And many more great voluntary benefits
