## About the role

Helion is hiring a Principal Applied Plasma Data Scientist specializing in physics‑grounded machine learning to accelerate experimental FRC plasma modeling. This role will focus on developing and validating advanced ML frameworks—such as differentiable‑physics models, PINNs, surrogate modeling, or hybrid physics+ML systems—while integrating these tools with simulation and diagnostics pipelines.

## What they're looking for

- PhD in Physics, Engineering, Applied Math, Computational Science, Machine Learning, or related field with emphasis on physics‑grounded modeling
- 10+ years of industry or research‑lab experience applying machine learning in experimental, simulation‑driven, or scientific R&D environments
- Expertise with physics‑informed or physics‑constrained ML methods, such as differentiable physics, PINNs, scientific ML, surrogate modeling, or reduced‑order models for complex physical systems
- Experience integrating ML models with scientific‑computing workflows, simulation tools, or experimental diagnostics
- Proficiency scripting for data parsing, model analysis, and visualization (MATLAB, Python, or similar, Fortran or HPC exposure valuable)
- Familiarity with magnetic diffusion, circuit coupling, or plasma‑dynamics modeling in pulsed‑power or electromagnetics systems
