We aim to commercialize fusion energy in 10 years.
We know what we’re doing - our leadership team has over 150 years of experience combined.
We’ve already been recognized for our work by the Department of Energy through awards and funding.
Our philosophy accepts no intellectual boundaries and celebrates creativity.
If you are searching for the best new ideas and share our vision, join us as a “Lead Vacuum Systems Engineer”. This is what you need to know:
Location: Knoxville TN, Boston (Woburn), Madison WI or Vancouver (BC)
Salary: Highly Competitive Plus Benefits
Contract: Permanent, full time
Reporting to: Director of Thermofluids Engineering

Type One Energy are looking for a Lead Vacuum Systems Engineer to drive the end-to-end design, integration, and optimization of complex vacuum systems for our stellarator fusion energy systems.
In this role, you will serve as the technical lead for vacuum systems across critical programs, ensuring robust performance in complex technical environments. This position is ideal for someone who thrives on solving complex engineering problems and leading multidisciplinary efforts from concept through commissioning.

You will play a key technical leadership role in developing ultra-high vacuum environments critical to plasma confinement and machine performance.

• Own the architecture, design, and system-level integration of advanced vacuum systems, from initial concept through operational deployment.
• Lead the vacuum system architecture for stellarator devices, including chamber design, pumping strategy, outgassing mitigation, and integration with magnetic and structural systems.
• Define system requirements and translate them into detailed specifications for vacuum components, assemblies, and controls.
• Lead vacuum-related trade studies, risk analyses, and system-level design reviews.
• Collaborate closely with plasma physics, magnet systems, cryogenics, and structural teams to ensure coherent integration of the vacuum envelope within the stellarator geometry.
• Interface with mechanical, electrical, controls, thermal, and manufacturing teams to ensure seamless integration across subsystems.
• Serve as the subject matter expert (SME) for vacuum engineering, mentoring junior engineers and reviewing their work for technical accuracy.
• Ensure all vacuum system designs meet industry and safety standards, including cleanliness, material compatibility, and reliability requirements.

• Drive continuous improvement initiatives and implement best practices for vacuum system design and maintenance.
