• Bachelor’s Degree in Mechanical, Aerospace Engineering or a related field; Master's or PhD is a plus. Alternatively, a minimum of 10 years specialized experience as a senior technician—with demonstrated responsibilities in system design, independent testing, and complex troubleshooting.
• Proven expertise in high vacuum systems design, analysis, and construction.
• Hands-on experience with vacuum components: chambers, pumps, seals, valves, ducts and clean room techniques.
• Experience integrating electrical testing in vacuum systems and pressurized systems
• Familiarity with ASME BPVC and B31.3 codes.
• Experience with radioactive or toxic gas vacuum systems, novel vacuum pumps, or material characterization

Responsibilities

• Design, analyze, and test advanced vacuum systems for target area chambers and diagnostics.
• Select and size vacuum components, including pumps, seals, ducts, and valves, ensuring performance in particle-free cryogenic environments.
• Rapid prototyping for fusion technology applications.
• Lead technical and engineering activities from concept development through final onsite commissioning of vacuum equipment and systems.
• Supporting high-voltage electrical switching operations and testing in a vacuum chamber
• Perform experiments to characterize materials for outgassing, permeability, and vacuum compatibility.
• Provide solutions to field issues related to vacuum system design and performance.
• Collaborate cross-functionally to educate and negotiate design requirements within a multidisciplinary team.
