About Fuse
We are building one of the most potentially consequential companies of the century. Our mission is to accelerate the world's transition to fusion energy while safeguarding humankind. This is not a normal company. This is not a normal job. We are committed for the long term to win.
About the Role
You'll be the operational backbone behind Fuse's leadership and facility — partnering closely with the C-Suite on calendars, travel, and high-stakes meeting prep, while also owning the day-to-day office environment so the rest of the team can focus on their work. This role spans both executive support and office operations, from board-meeting logistics to vendor management to new-hire onboarding.

Own end-to-end travel logistics: transportation, accommodations, itineraries, and expense reporting.
Triage C-Suite email, flag urgent items, and draft responses as needed.
Prepare executives for high-stakes meetings with agendas, briefing materials, and summaries.
Liaise between the C-Suite and internal teams to drive alignment, clear communication, and timely follow-through.

Own office supply and inventory management across common areas and workspaces.
Coordinate new hire onboarding logistics, workspace setup, equipment, access, and day-one readiness, in partnership with HR and IT.
Plan and execute company events, offsites, all-hands, and culture programming.
Manage onsite visitor and guest experience, including reception, conference room coordination, and VIP hospitality.
Own branded merchandise programs, including vendor sourcing, inventory management, and coordination of swag for onboarding, events, and partner gifting.
Anticipate operational needs, surface gaps proactively, and resolve issues before they escalate.
Minimum Qualifications

Proficiency with Outlook, JIRA, Teams, and SharePoint, or equivalent calendar, project-tracking, communication, and documentation tools.
Strong organizational skills and discretion handling sensitive, confidential information.
Excellent written and verbal communication skills.
Preferred Qualifications
Experience supporting a CEO or C-Suite in a startup or high-growth environment.
Experience planning company events, offsites, or culture programming.
What We Value
Obsess about the details — sloppy work costs us later, so do it right the first time.
Care — pick up the trash. Do things no one asks you to do. Go the extra mile because you care.
Act with urgency — every hour matters more than it feels like it does.
Be responsible for the outcome, not just the task; if it is not working, it remains your problem until it is fixed.
Assume good intent — disagree openly, then commit fully once a call is made.
Additional Requirements
This is not a remote position and will require relocation if not already local to Fuse's San Leandro, CA facility.
Position may require extended hours to support executive schedules and company events.
Benefits
Medical, dental, and vision coverage.
Relocation assistance for roles that require it.
Flexible time off. Take what you need, no accrual tracking.
2 weeks of paid time off built into the end of each year (subject to team and business needs).
Supportive leave of absence policies.
Paid leave for new parents.
