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 experienced, highly motivated magnet engineers to join its rapidly growing team. The magnet engineering roles will design, build, and test high temperature superconducting (“HTS”) magnets. HTS magnets are foundational components of Thea Energy’s planar coil stellarator, making compact, simpler, and lower-cost fusion systems possible. As part of a rapidly growing team, you’ll be part of the organizational build-up of a leading fusion energy company. These roles will have a high degree of autonomy and must be able to move quickly. The Thea Energy team is comprised of self-motivated, creative, and fun individuals with an excitement for solving complex problems. Key Responsibility Areas: Rapidly design, build, and test HTS magnets Develop specifications for magnets based on system design and performance goals Optimize magnet design and run analysis using Multiphysics simulation software (e.g. Ansys EM, Structure, COMSOL, etc.) Develop design tools, data analysis software, and algorithms using Python or similar Incorporate design for manufacturing principles and support first builds Produce design specifications and collaborate with vendors to get quotes and deliver hardware that meets qualifications Support the implementation of tooling and manufacturing Design and execute magnet testing Track and report results and progress against program goals and milestones Communicate and collaborate with internal and external stakeholders Ideal Experience & Skillsets: Experience with magnets, cryogenics, vacuum systems, or transformer design Experience in design using CAD software (e.g. Solidworks, CATIA, NX, etc.) Experience with Ansys and/or COMSOL Experience specifying machining, welding, and fabrication requirements Ability to work through and solve highly multidisciplinary engineering problems Ability to take initiative, work independently and as part of a team Ability to execute and flourish in a fast-paced, rapidly changing environment Comfortable working to aggressive deadlines Exceptional work ethic Strong team member with clear communication and collaboration skills Innate desire to learn, innovate, and critique ideas including one’s own At least a bachelor’s degree in physics, computer science, electrical engineering, mechanical engineering, materials engineering, or related fields Experience with magnetic confinement fusion, aerospace, medical devices, or other highly technical industries is ideal Company Benefits: Salary range $110,000-$180,000 Comprehensive health benefits (e.g. medical/dental/vision) Employee equity stock options 20 days PTO 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. It’s not necessary to meet all of the skillsets outlined above. Please feel free to send us a note and tell us why you would still be a great fit for this role or Thea Energy. Diversity and Inclusion: Thea Energy is an equal opportunity employer committed to creating a company of diverse backgrounds. By creating a diverse environment, we will bring new ideas and approaches to solving some of the world’s hardest (and most important) problems. All qualified applicants will receive consideration for employment without regard to race, color, religion, sex, gender, sexual orientation, gender identity or expression, national origin, family or marital status, age, disability, veteran’s status, or other characteristic protected by applicable laws and regulations. #J-18808-Ljbffr Thea Energy
