Numerical Modeling Engineer

We are looking for a Numerical Modeling Engineer to develop high-fidelity simulation tools that predict and de-risk the behavior of our superconducting magnets. Your work will span electromagnetic, thermal, and transient multiphysics modeling - including quench dynamics - and will directly inform design decisions for conductors, coils, and protection systems.

Responsibilities

Develop high-fidelity simulation tools that predict and de-risk the behavior of superconducting magnets; Model electromagnetic, thermal, and transient multiphysics including quench dynamics; Develop custom solvers, reduced-order models, automation pipelines, and internal Python/C++ frameworks; Provide design feedback, risk assessment, and cross-team collaboration with magnet engineers, quench protection specialists, and test engineers; Translate complex physics into clear engineering recommendations

Requirements

Degree (MSc or PhD) in Electrical Engineering, Applied Physics, Computational Engineering, or a related field; Strong foundation in electromagnetics and physics-based numerical modeling (e.g., FEM, nonlinear coupled systems), with the ability to implement and extend models programmatically; Experience with multiphysics and transient simulations (e.g., electromagnetic–thermal coupling, fast transients); Proficiency in at least one scientific programming language (Python, MATLAB, C++, or similar), with interest in developing internal modeling tools and workflows; You question assumptions and validate results critically; You are comfortable building models from first principles; You thrive in a startup environment where tools, processes, and standards are still evolving

Nice to have

Valued Experience (not all required): Electromagnetic numerical modeling; COMSOL or other commercial FEM tools; Modeling of high-current or high-field devices; Thermal modeling and heat transfer in complex systems; Experience building internal engineering tools rather than relying purely on GUI-based workflows; Prior experience with superconductors or HTS magnets is a plus

Benefits

Impact: Your simulations will directly shape the magnets that enable commercial fusion energy; Ownership: Define modeling standards and influence core design decisions; Frontier Engineering: Work at the intersection of high-field electromagnetics, cryogenics, and advanced numerical methods; Collaboration: Join a team combining deep superconducting expertise with advanced computational capability
