Job Summary:
Helion is a fusion power company based in Everett, WA, focused on building the world's first fusion power plant for clean electricity. They are seeking a Senior Plasma Data Scientist to develop and validate synthetic diagnostic models for FRC plasma behavior to enhance diagnostic accuracy and plasma performance interpretation.
Responsibilities:
โข Develop and validate machineโlearning frameworks for FRC plasmaโdynamics, leveraging physicsโgrounded ML approaches (e.g., differentiable physics, PINNs, surrogate modeling, or hybrid physics+ML systems)
โข Integrate ML models with existing simulation tools and experimentalโdiagnostic pipelines to enable hybrid physics + dataโdriven validation workflows
โข Reproduce experimental plasma conditions within ML modeling workflows to support interpretation of magnetic diffusion, circuit response, and diagnostic measurements
โข Generate analysis scripts for postโprocessing, parsing model outputs, and visualizing correlations between MLโbased predictions and experimental results
โข Collaborate with plasmaโphysics, pulsedโpower, and transientโmagnetics experts to expand the fidelity and fusionโrelevance of MLโenabled modeling frameworks
โข Communicate results with rigor and clarity through reports, presentations, and technical visualizations for research stakeholders
Qualifications:
Required:
โข PhD in Physics, Engineering, Applied Math, Computational Science, Machine Learning, or related field with emphasis on physicsโgrounded modeling
โข 3+ years of industry or researchโlab experience applying machine learning in experimental, simulationโdriven, or scientific R&D environments
โข Expertise with physicsโinformed or physicsโconstrained ML methods, such as differentiable physics, PINNs, scientific ML, surrogate modeling, or reducedโorder models for complex physical systems
โข Experience integrating ML models with scientificโcomputing workflows, simulation tools, or experimental diagnostics
โข Proficiency scripting for data parsing, model analysis, and visualization (MATLAB, Python, or similar; Fortran or HPC exposure valuable)
โข Familiarity with magnetic diffusion, circuit coupling, or plasmaโdynamics modeling in pulsedโpower or electromagnetics systems
