• Strong operational instincts: organization, prioritization, project tracking, and an ability to proactively identify gaps and blockers
• High comfort working in tools like Slack, Notion, and Google Workspace; experience maintaining project dashboards or documentation systems
• A mindset of ownership, anticipation, and partnership; someone who sees around corners and stays one step ahead
• High integrity, discretion, and professionalism when handling sensitive information

Desirable

• We’re looking for a highly organized, proactive, and trusted Executive Assistant to partner with our CIO
• This role is a blend of strategic coordination, operational excellence, and executive enablement
• You’ll manage the CIO’s operating rhythm, maintain visibility across key initiatives, and create structure that keeps the organization aligned and moving efficiently
• This is not traditional administrative support
• This is a high-touch and strategic role in which you’ll develop a deep understanding of business priorities, challenges, and opportunities, and ensure our CIO has the relevant information at the right time
• You will help shape how decisions are made, how information flows, and how we maintain momentum across a fast-growing, high-stakes technical organization
• Own the CIO’s calendar and operating rhythm, ensuring meetings have clear purpose, deep-work time is protected, and weekly/monthly cadences run smoothly
• Manage communication and context across Slack, Notion, and email, drafting updates, summarizing meetings, and ensuring decisions and next steps are captured clearly
• Maintain the CIO’s project dashboard, tracking milestones, risks, owners, and follow-through across multiple cross-functional initiatives
• Act as a coordination hub and CIO proxy, aligning stakeholders, managing vendor and partner interactions, and ensuring expectations and timelines remain clear
• Create and maintain operational structure, including weekly CIO syncs, daily briefs, board/investor prep, compliance reviews, and ongoing initiative updates
