Job description

Role Overview

The R&D team’s mission at CFS is to vet potential technical solutions in order to guide the overall SPARC subsystem design, and plan for the technology needs of future fusion power plants and spin-off projects. The Electromagnetics Analysis Engineer will perform electromagnetic (EM) analysis of superconducting magnets using finite element and other methods. This analysis includes the non‑linear, anisotropic behavior of high‑temperature superconductors (HTS) in both insulated and non‑insulated magnet systems.

Incorporating complex multi‑physics (heat transfer, fluids, mechanics, etc.) system behavior into simplified, elegant network circuit and/or FEA models is also crucial to model the multi‑physics behavior of superconducting magnets. The Electromagnetics Analysis Engineer will work with a team of experimentalists and engineers to validate simulations against experimental data.

Familiarity with both commercial finite element analysis software packages and developing custom in-house code in Python and extensions of commercial packages is necessary.

This work is conducted within a multi‑disciplinary team of physicists and engineers. Participation and clear, concise communication in design and test activities is necessary to inform design decisions and correlate models to experiment.

Responsibilities

• Perform electromagnetic analysis of superconducting magnets and inform design decisions
• Work with experimental teams on instrumentation, measurement, and correlation of experiment to analysis
• Develop new numerical tools, as needed, to facilitate multi‑objective design optimization of high‑temperature superconducting magnets
• Perform non‑linear, highly‑anisotropic EM simulations in complicated geometries
• Identify enabling technologies in the modeling and construction of high‑temperature superconducting magnets
• Prepare reports and presentations as necessary
• Mentor and guide new members of the team in magnet design and analysis as necessary
• Perform activities such as sitting for extended periods of time

Qualifications

• At least a Bachelor’s Degree in electrical engineering or another relevant field with an EM background (physics, mechanical engineering, etc.)
• 7+ years of experience modeling electromagnetics using finite element method
• A strong background and theoretical understanding of computational electromagnetic analysis
• Experience modeling non‑linear physics
• Experience with commercial finite element tools (COMSOL preferred)
• The ability to customize commercial finite element tools or develop new in‑house codes in modern programming languages such as Python/MATLAB/C/C++
• Able to quickly grasp experimental setups and analyze data to validate models
• Ability to clearly express and critique ideas
• Ability to innovate toward solutions to complex problems
• An emphasis on elegance and simplicity over complexity
• A drive toward commercially viable solutions
• A history of thriving in fast‑paced, dynamic environments
• Values that align with our company’s values of integrity, execution, impact, and self‑critique
• Multi‑physics FEM modeling with electromagnetics, heat transfer, mechanics, fluids, structures, etc.
• Experience working with superconducting non‑linear physics
• Developing equivalent thermal and electrical circuit models
• Familiarity with best practices in coding and software development
• Dedication to safety to mitigate industrial hazards that may include heat, cold, noise, fumes, strong magnets, lead (Pb), high voltage, high current, pressure systems, and cryogenics
