Job description

About Fuse

Fuse is on a mission to accelerate the world’s transition to limitless clean energy.
We’re builders, breakers, and fixers who get sh!t done - building pulsed-power and fusion devices. The team moves fast, iterates faster, and sweats the details.

If “impossible” sounds like a to-do list, you’ll fit right in.
This is not a regular job. Fusers are on a mission to change the world.

About the Role

Fuse is searching for our operations sherpa. A unique Fuser that can keep pace with our founder’s velocity. You’ll guard time, kill friction, and turn chaos into clean execution. Calendar athlete. Comms router. Travel ninja. Ops whisperer. All in one.

About You

  • Trusted gatekeeper: Discretion first.

  • Polished communicator: Impeccable grammar, no typos.

  • Chief Time Officer: You enjoy planning vacations and events down to the minute.

  • Own the tech stack: Notion, Slack, Google, and Microsoft. Driving these platforms are second nature.

  • Protect the momentum: Anticipate needs, surface blockers early, coordinate cross-team actions, and keep decisions moving.

  • Master logistician: Travel that works, meetings that start on time, rooms that are ready, documents prepped.

  • Project-management instincts: you notice what’s missing and add it before anyone asks.

Minimum Requirements

  • 3+ years supporting C-level leaders in high-velocity environments.

  • Ruthless prioritization, exceptional written brevity, and calm under shifting constraints.

  • Mastery of calendar tooling, travel platforms, and productivity stacks.

  • On-site bias and willingness to handle “whatever it takes” moments.

Bonus points

  • Startup experience in defense/energy/advanced hardware.
