About the Position
Senior Superconductor Engineer
We are seeking a highly skilled Senior Superconductor Engineer to join our innovative team at Helion in Everett, WA. This role is pivotal in advancing our mission to build the world's first fusion power plant, enabling a future with unlimited clean electricity.
Responsibilities
You will be responsible for the full lifecycle of superconducting hardware-from simulation and design through build, test, and integration-while coordinating across internal teams and external partners to qualify technologies for deployment in Helion's fusion machines. Your duties will include:
- Analyzing magnetic fields and their coupled effects (e.g., Lorentz forces, thermal loads, structural stress) using tools such as COMSOL and ANSYS
- Evaluating mechanical loading and failure modes in high-field superconducting environments
- Designing, building, testing, and iterating superconducting magnet systems in both standalone test stands and integrated fusion machines
- Developing experimental plans and diagnostics to validate performance under realistic operating conditions
- Analyzing the impact of superconducting field configurations and architectures on plasma performance
- Collaborating closely with plasma physicists and machine designers to optimize system-level outcomes
Requirements
- Demonstrated experience delivering a functional superconducting system that has been successfully deployed or operated in a real-world application
- Strong background in electromagnetics, superconductivity, and multiphysics modeling
- Hands-on experience designing and testing superconducting magnets or related systems
- Proficiency with COMSOL, ANSYS, or equivalent simulation tools
- Experience working across disciplines including mechanical, electrical, and plasma physics domains
- Proven ability to independently drive complex technical projects from concept to execution
We Offer
Our total compensation package includes benefits, including but not limited to:
- Medical, Dental, and Vision plans for employees and their families
- 31 Days of PTO (21 vacation days and 10 sick days)
- 10 Paid holidays, plus company-wide winter break
