Job description

About Rune
Every solar and wind power plant is a latent data center. Rune connects wasted power to the compute that needs it. Solar plants generate electricity the grid can't take: clipped by inverters, curtailed by operators, gone before it ever reaches a meter. Meanwhile, AI needs more power than new construction can deliver in time.

Location: Mountain View, CA

The Role
You’ll help the founders spend their time on what matters most. You’ll keep their schedules, commitments, and day-to-day details running smoothly, and you’ll become a trusted partner who spots what’s needed before anyone asks.

What You’ll Do

• Own the founders’ calendars: protect focus time, resolve conflicts, and keep priorities visible.
• Prepare them for meetings with agendas, background notes, and follow-up on action items.
• Serve as the first point of contact for investors, partners, candidates, and customers, drafting replies and routing what needs their attention.
• Plan travel end to end, from itineraries and bookings to backup plans when things change.
• Reconcile expenses and receipts in line with company policy.
• Help organize team gatherings, off-sites, and visitors to the office.
• Take on special projects and help shape how the founders’ office runs as the company grows.
• Handle confidential financial, legal, and people matters with complete discretion.

What You Bring

• Required to have supporting at least one CEO ideally in a startup or high-growth company.
• Sound judgment, discretion, and clear, professional writing.
• Comfort with shifting priorities and the initiative to move forward without waiting for direction.
• Strong skills with Google Workspace, Slack, and expense and travel tools, plus a willingness to learn new ones quickly.
• Curiosity about energy, compute, and infrastructure (no technical background required).
• The ability to work in person at our Mountain View office five days a week, with flexibility for occasional time-sensitive requests.

Nice to have

• Experience coordinating events or off-sites.
• Exposure to finance, legal, or investor-facing work.

What We Offer: Competitive base and strategic ownership in what we believe will be one of the largest infrastructure build-outs of the decade. Great benefits, and office perks!

Rune is an equal opportunity employer. We celebrate diversity and are committed to creating an inclusive environment for all employees.
