About us

Acceleron Fusion is developing muon‑catalyzed fusion—a path to clean, abundant energy. Building on research sponsored by the U.S. DOE, we have recently raised a $24M Series A venture capital round and have already logged 100+ hours of muon-catalyzed fusion in tests at the Paul Scherrer Institute. Our collaborators include PSI, Oak Ridge, Argonne, Fermilab, and several universities. Join a team where fundamental physics meets application-oriented engineering, and your designs could help move our technology from the laboratory to a commercial energy source.

We have an opening for an Accelerator Physicist who will play a key role in the design and optimization of muon production systems for our fusion technology.

What you'll do:

Design and optimize particle accelerator systems and beamlines for muon production
Develop simulation models of accelerators and beams to analyze beam dynamics and particle interactions
Collaborate cross-functionally to integrate accelerator designs into our fusion system
Contribute to experimental planning and data analysis
Help establish technical specifications for system components
Author technical papers and contribute to the company's scientific publications, presenting research at scientific conferences

What we're looking for:

PhD in Physics, Electrical Engineering, or a related field, preferably with a focus on accelerator physics
Strong understanding of beam dynamics and accelerator systems
Demonstrated understanding of accelerator physics principles for beamlines, synchrotrons, and storage rings, including the theory of polarized beams
Experience with particle accelerator simulation tools
Track record of working successfully with other scientists and engineers to solve complex technical challenges
Excellent analytical and problem-solving abilities
Strong communication and collaboration skills, and ability to work in a fast-paced team

Preferred Qualifications (not required)

Post-doctoral research experience in accelerator physics
Hands-on experience with physics/particle accelerator operations or development
Background in muon physics or muon beamline design
Familiarity with high-frequency electronics or RF accelerator components.
Experience with safety systems for high-power or high-voltage electronics.
Programming skills in Python, MATLAB, or similar tools
CAD software proficiency (e.g. SolidWorks, AutoCAD)

Details and Logistics:

This is a full-time, onsite role working from our facility in Cambridge, MA.
Travel (including international) for several weeks per year is required.
Our benefits package includes health & dental insurance, retirement savings with company contribution, stock options, paid time off, and 11 company holidays.
The salary range for this role is $110,000 to $150,000. This range represents the minimum and maximum base compensation Acceleron Fusion reasonably expects to pay for this position. The specific salary offered will be determined based on relevant factors including skills, experience, qualifications, and location. This position may also be eligible for additional compensation such as bonuses, equity, or other benefits.

Acceleron Fusion is an equal opportunity employer, committed to building a welcoming, respectful, and inclusive workplace. We welcome applications from all qualified candidates regardless of background.
