Executive Assistant to CEO and Co-Founder

Location: Mountain View, CA

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.

Rune deploys hardware, software, and financial solutions to put this power to work. We build modular micro data centers that install directly at solar sites, bypassing the traditional grid entirely and turning stranded power into compute. We're backed by Spark Capital, Union Square Ventures, and Lower carbon Capital.

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.

• 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.

• 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.

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

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!
