About the Job

Requirements

  • A high school diploma or equivalent is required; an associate degree in a technical discipline is preferred.
  • At least 5 years of hands-on technical experience in shop fabrication, system assembly, hardware testing, or high-tech manufacturing environments such as fusion, aerospace, superconducting magnets, or heavy industry.
  • Demonstrated experience building, operating, and troubleshooting at least two of the following: superconducting magnet or nuclear fusion system testing; high-vacuum or ultra-high-pressure systems; cryogenic or fluid-handling systems; high-power electrical, control systems, or industrial wiring; electromechanical, automated, or PLC-driven equipment.
  • Proficiency in reading and interpreting mechanical drawings, schematics, and wiring diagrams.
  • Skill with hand tools, power tools, precision measuring instruments, and basic shop machining equipment such as saws and manual mills.
  • Familiarity with software tools for basic documentation, logging, or reporting, such as Microsoft Office.
  • Ability to safely lift up to 50 pounds and work comfortably around high-voltage, high-field, and cryogenic environments.

Responsibilities

  • Assemble, wire, plumb, and commission complex test articles, high-power test stands, cryogenic loops, and high-vacuum test equipment.
  • Operate multi-day test systems and perform real-time, hands-on troubleshooting of mechanical, electrical, cryogenic, thermal, and vacuum system failure modes alongside test engineers.
  • Support rapid development of new procedures, measurement methods, and custom tooling for novel tests, enabling exceptional quality and data integrity.
  • Partner with test, magnet, manufacturing, electrical, and mechanical engineering teams to align test scope and requirements and ensure successful tests and results.
  • Enforce safety protocols in high-current, high-field, and cryogenic environments.
  • Maintain tool and workspace organization using 5S, and ensure precision test equipment is calibrated and maintained.
  • Guide and mentor technicians and engineers in shop best practices, schematic reading, and safe testing procedures.

Desired Qualifications

  • Experience executing automated test routines using LabVIEW, Python interfaces, or PLCs/HMIs.
  • Familiarity with reflow soldering, PCBA manufacturing or repair, or micro-soldering.
  • Experience creating or improving test procedures, quality control standards, and non-conformance reporting.
  • Rigging, overhead crane, and forklift operation certifications or experience.

About the Company

Thea Energy

Develops fusion power via planar-coil stellarators

Thea Energy develops fusion-based power technology to provide scalable, zero-emission baseload electricity for utilities and heavy industry. Its approach uses a reimagined stellarator with flat, planar superconducting coils controlled by software-defined systems, replacing the traditional complex magnet geometry to lower costs and improve serviceability. Its Eos neutron-source device and Helios commercial power plant concept illustrate a pipeline from research to grid-ready power, backed by DOE milestones and public-private partnerships. The company aims to commercialize fusion as a dependable grid-level energy source and win long-term offtake agreements with utilities and large customers.
