High Voltage Electrical Engineer

Acceleron Fusion•Cambridge, MA

7d•$110,000 - $150,000•Onsite

About The Position

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’re looking for a high-voltage electrical systems engineer to design advanced beam-control hardware for our fusion experiments. You will develop high-voltage and RF solutions that enable precise manipulation of particle beams at energies from kilovolts to megavolts.

Requirements

B.S., M.S., or Ph.D. in Electrical Engineering, Physics, or a closely related field.
Five years experience designing high voltage or pulsed power systems.
Proficiency with COMSOL, ANSYS, or similar multiphysics simulation tools.
Proficiency with circuit design tools (e.g. Altium).
Hands‑on lab experience: high voltage safety standards and best practices; lab instrumentation; practical troubleshooting.
Thoughtful collaboration skills, able to interact and work closely with people from other technical disciplines and backgrounds.
Demonstrated time management and organizational skills.
Excellent written and verbal communication abilities.

Nice To Haves

Experience with particle accelerators, charged particle optics, or high vacuum systems.
Proficiency with GEANT4, FLUKA, MCNP, or similar Monte Carlo simulation tools.

Responsibilities

Analyze, model, and mitigate electrical-breakdown and insulation challenges in high-voltage structures and circuits.
Design kilovolt-to-megavolt electrostatic systems—for example using Marx generators, Cockcroft‑Walton stacks, or Pelletrons —for particle beam acceleration and cooling.
Architect RF power and energy recovery systems using Klystrons, Magnetrons, waveguides, and similar components.
Build multiphysics models incorporating electromagnetics, heat transfer, fluid flow, and particle transport.
Build prototypes and conduct lab tests.
Generate clear design docs, test plans, and risk analyses that support rapid iteration and safe operations.
Travel with the team (including international travel) to integrate your hardware at beamline facilities and carry out experiments.
