About the Role

About Thea Energy:

Thea Energy is leveraging recent breakthroughs in stellarator physics and engineering to create a faster and simpler approach to commercializing fusion energy. The company is reinventing the stellarator using computer-controlled arrays of planar coils thereby replacing the intricate, complex modular magnets required in all other stellarator architectures. Thea Energy is on a mission to create a limitless source of zero emission energy for a sustainable future.

Position Overview:

Thea Energy is seeking a detail-oriented HTS Magnet Multiphysics Modelling Engineer to join its rapidly growing magnet engineering team. In this role, you will support the design, analysis, and testing of high temperature superconducting (“HTS”) magnets, foundational components of Thea Energy’s planar coil stellarator. You will work closely with senior engineers to develop and run HTS Magnet Engineering tools to simulate and predict magnet system performance. Candidates will need to be familiar with magnetostatic, quench and AC loss analysis techniques. This position will also require you to work closely with manufacturing and test teams to ensure analytical assumptions and test data are aligned with your analysis and simulation needs. This is an excellent opportunity for an ambitious early-career engineer or analyst to build deep expertise in HTS magnet technology within a fast-paced fusion energy company.

Key Responsibility Areas:

Utilize your experience to develop industry state-of-the-art analytical models of HTS Magnet Systems

Run and maintain Multiphysics simulations (e.g. Ansys EM, Structural, COMSOL) under the direction of senior engineers

Collect, process, and analyze data from magnet design studies and test campaigns

Build and maintain data analysis tools, scripts, and dashboards using Python or similar languages

Support documentation of magnet specifications, test procedures, and results

Track program metrics and help prepare progress reports against milestones

Assist with organizing and maintaining design and test records, drawings, and vendor documentation

Support coordination with vendors and internal stakeholders on data and documentation needs

Identify data quality issues, trends, and anomalies and flag them to the engineering team

Familiarity with electro-mechanical, magnetostatic, quench and AC loss analysis

Opportunities to get involved in many aspects of the design, manufacturing and testing of these magnet systems

Ideal Experience & Skillsets:

1–3 years of experience in engineering, physics, or a data-analysis-focused role; internship or academic research experience with magnets, cryogenics, or electromagnetics a plus

Proficiency with Python (or similar) for data analysis and scripting

Familiarity with Multiphysics simulation tools (Ansys, COMSOL) or strong willingness to learn quickly

Working knowledge of CAD software (Solidworks, CATIA, NX) a plus

Strong analytical and quantitative problem-solving skills

Excellent organizational skills and attention to detail

Ability to work independently on well-defined tasks and escalate ambiguity appropriately

Comfortable working to aggressive deadlines in a fast-paced, rapidly changing environment

Clear written and verbal communication skills

Genuine curiosity and desire to learn magnet engineering fundamentals

At least a bachelor’s degree in physics, electrical engineering, mechanical engineering, materials engineering, computer science, or a related field

Requirements:

Ability to occasionally lift up to 50 lbs.

Ability to perform activities such as typing, standing, or sitting for extended periods of time.

Willingness to occasionally travel or work required nights/weekends/on-call.

Ability to work in a facility that contains industrial hazards including heat, cold, noise, fumes, strong magnets, high voltage, high current, pressure systems, and cryogenics.

Company Benefits:

Salary range $85,000-$120,000

Comprehensive health benefits (e.g. medical/dental/vision)

Employee equity stock options

20 days PTO
