Thea Energy is commercializing fusion energy using breakthroughs in stellarator physics and engineering. The company is reinventing the stellarator with computer-controlled arrays of planar coils, replacing complex modular magnets in traditional architectures, to create a limitless source of zero-emission energy.
As Senior Test Engineer, you will develop and own the test validation strategy for High-Temperature Superconducting (HTS) magnets, cryogenic systems, and high vacuum components. You will define testing milestones required to qualify these critical subsystems and act as a subject matter expert for the test engineering team.
Key responsibilities include:
• Lead, mentor, and grow a team of engineers and technicians, fostering a culture of rigorous data integrity and first-principles problem-solving.
• Oversee the design, build, and commissioning of large, custom cryogenic and high-power test stands.
• Analyze complex datasets to troubleshoot system-level failure modes, working closely with magnet, electrical, and controls teams to ensure test results directly inform and de-risk next-generation stellarator design.
• Lead relationships with key vendors for specialized hardware and advanced test facilities, managing high-value procurement contracts and coordinating external design, build, and validation efforts to meet aggressive project timelines.
• Establish and enforce rigorous safety protocols for high-voltage, high-field, and cryogenic environments, ensuring all operations meet or exceed IEEE, ANSI, and IEC standards.
Requirements:
• 8+ years of hardware-centric test engineering experience in high-stakes environments (fusion, aerospace, superconducting magnets, or equivalent).
• BS or MS in Electrical Engineering, Applied Physics, or related field.
• Proven track record managing the verification and validation lifecycle for integrated systems.
• Mastery of LabVIEW and Python, with expertise automating complex, multi-day cryogenic and electromagnetic tests.
• Demonstrated ability to work with high autonomy and make critical engineering decisions under tight deadlines.
• Exceptional ability to translate complex test data into actionable insights for executive leadership and external stakeholders.
• Ability to work through and solve highly multidisciplinary engineering problems.
• Ability to occasionally lift objects up to 50 lbs.
• Exceptional work ethic, clear communication, and collaboration skills.
