Fusion R&D Technician

About Acceleron Fusion

Acceleron Fusion is on a mission to revolutionize clean, abundant energy through muon-catalyzed fusion—a groundbreaking approach that leverages intense muon beams to trigger nuclear fusion at room temperature. Spun out of research funded by the U.S. Department of Energy, we recently closed a $24 million Series A and operate an integrated fusion testbed on the high‑intensity proton accelerator at the Paul Scherrer Institute (PSI). Our partners include PSI, Oak Ridge, Argonne, Fermilab, and top universities.

What you'll do

• Assemble and leak-test vacuum hardware and process piping.
• Build cable assemblies, printed circuit boards, and electronic assemblies.
• Assemble intricate mechanical and electrical subsystems.
• Travel to partner labs to install, align, and troubleshoot mechanical systems during experimental operations.
• Run tests and collect data.
• Maintain a clean and organized workspace and stockroom of mechanical and electrical components.

What we're looking for

• At least 2 years experience working in a research and development environment.
• Ability to read electrical schematics, mechanical drawings, and piping diagrams.
• Proficiency with standard office software (Microsoft, Google, Slack, etc.).
• Problem-solving skills and the ability to build and troubleshoot complex systems.
• Demonstrated time management and communication skills.

Preferred Qualifications (not required) 

• Proficiency with soldering and electronics assembly.
• Proficiency with MIG/TIG or laser welding.
• Proficiency using machine tools, CAD/CAM, or digital fabrication equipment.
• Hands-on familiarity with vacuum, cryogenic, or pneumatic systems.
• Experience doing mechanical or electrical work under a microscope.

Details & Logistics

• This is an onsite position working 40 hours/week from our facility in Cambridge, MA.
