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.

Key Responsibility Areas

• Assist in generating and updating test documentation, including standard operating procedures (SOPs), work instructions, and quality criteria for HTS magnet testing.
• Support design, prototyping, and commissioning of custom test fixtures and equipment.
• Work alongside test engineers, magnet designers, and manufacturing engineers to incorporate "lessons learned" from testing into future designs.
• Manage virtual and physical inventory, organize assembly areas, and update manufacturing Bills of Materials (BOMs).
• Assist hardware procurement, evaluating vendor specs, and ensuring incoming parts meet quality standards.
• Track test metrics and results, and progress against critical program milestones.

Ideal Experience & Skillsets

• Currently pursuing a Bachelor’s or Master’s degree in Mechanical Engineering, Aerospace Engineering, Materials Science, or a related technical field.
• Strong foundational understanding of engineering drawings and spatial mechanics (exposure to GD&T is a major plus).
• Hands-on project experience (e.g., Formula SAE, rocketry club, robotics club, etc.) involving mechanical or electrical hardware design, build, and test.
• Familiarity with relevant hardware and software for developing test controls including LabView, Python, National Instruments, thermocouples and voltage taps, and similar equipment and software
• Direct experience with fabrication or assembly processes such as machining (hand tools, manual mill, CNC), fastened and bonded assemblies, soldering, etc.
• Familiarity with CAD software (e.g., SolidWorks, NX).
• Ability to work through and solve highly multidisciplinary engineering problems
• Ability to take initiative, work independently and as part of a team
• Exceptional work ethic, with clear communication and collaboration skills
• Ability to occasionally lift objects up to 50 lbs.

Company Benefits

• Salary range $21 - $25/hour

Requirements

• Ability to occasionally lift up to 50 lbs.
• Ability to perform activities such as typing, standing, or sitting for extended periods of time.
• 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.

Key Responsibilities

• Assist in generating and updating manufacturing documentation, including standard operating procedures (SOPs), work instructions, and quality criteria for HTS magnet assembly.
• Support design, prototyping, and commissioning of custom manufacturing tooling, fixtures, and equipment.
• Work alongside magnet designers and manufacturing engineers to incorporate "lessons learned" from the shop floor into future designs.
• Manage virtual and physical inventory, organize assembly areas, and update manufacturing Bills of Materials (BOMs).
• Assist hardware procurement, evaluating vendor specs, and ensuring incoming parts meet quality standards.
• Track production metrics, test results, and progress against critical program milestones.
