How do you turn a decades-old dataset into an industry-leading medical coding agent? Teach an AI receptionist to book appointments in Spanish? Automatically generate working data connectors from API docs? Build agents that write, test, and deploy their own software packages?
Fractional AI is focused on putting frontier AI to work. We’re a group of veteran Silicon Valley builders who care deeply about getting complex AI systems built right, with strong conviction about what makes them succeed.
We're backed by Anthropic, Blackstone, Hellman & Friedman, Goldman Sachs, General Atlantic, Leonard Green & Partners, Apollo Global Management, GIC, and Sequoia Capital.
We're headquartered in SF with offices in NYC, Raleigh-Durham, and Dubai.
The Role
You’ll be the operational backbone supporting our CEO and CTO directly, and developing a deep understanding of their priorities, working styles, and what good looks like for each of them. It’s a role where your judgment, taste, and systems thinking show up every day.
Part calendar owner — you develop a real point of view on how their time should be spent and help them protect it.
Part systems builder — you design the workflows and rhythms that keep executives organized and aligned.
Part communications operator — you communicate effectively, coordinate what needs to move, and make sure the right things get attention at the right time.
Part operator — you proactively spot the gaps and keep things moving.
If you treat upward management as a craft and get genuine energy from making great leaders even more effective, this role is for you.
What You'll Do
Own the calendar with a point of view: Manage complex, high-volume scheduling for our CEO and CTO. You’ll develop a point of view on their priorities and use that context to make smart calls.
Keep them ahead of what’s coming: Track open commitments, surface blockers, and make sure executives are informed, prepared, and ready for what’s next.
Build systems that create leverage: Design and maintain the intake processes, communication rhythms, and workflows that keep the executive team organized and aligned.
Be the communications layer: Draft, triage, and coordinate communications on behalf of the CEO and CTO. Synthesize inbound into clear recommended actions.
Make the logistics invisible: Plan and execute complex travel, meetings, team gatherings, and offsites with a high bar for experience and detail.
Be a calm, trusted presence: Act as a steady, positive and trusted point of contact across internal teams, external clients and partners, and stakeholders.
What You Bring
Executive support experience in a high-growth environment: You’ve supported senior leaders through fast-moving, high-stakes periods. We typically look for 5–8 years, but we care more about your prior roles and impact than years on a resume.
Upward management as a craft: You know how to keep busy leaders organized, informed, and accountable. You anticipate what they need, flag what they haven’t seen yet, and take pride in making them more effective.
Strong written communication: Excellent written communication skills, with the ability to write clearly and naturally in someone else’s voice when needed.
A bias for systems and leverage: You’re always looking for ways to make the operation run more smoothly — through better systems, processes, and tooling.
Sharp prioritization instincts: You anticipate conflicts, make tradeoffs independently, and surface what needs attention. You can hold a lot of context at once and keep the rhythm going without creating overhead.
Excitement about AI tools: You’re excited about how AI can create leverage in your own workflow.
Presence, composure, and discretion: People trust you quickly because you’re calm under pressure, thoughtful in how you engage, and consistent in how you show up
