Chief of Staff
AfterQuery is hiring a Chief of Staff to work directly with our founders as we scale to become one of the fastest-growing AI companies of all time. You will be the operational backbone of the company—owning our hiring pipeline, managing day-to-day administration, and ensuring the founding team's time is protected and focused on what matters most.
This is an in-person role. You'll be embedded with the founding team in San Francisco, moving at the speed of the company.
Company Overview
AfterQuery is a research lab investigating the boundaries and capabilities of artificial intelligence through novel datasets and experimentation. Our customers are the foundation model labs—we serve all of the frontier AI labs.
We are based in San Francisco, CA, and have raised funding from top investors, including Y Combinator and BoxGroup, ex-partners from Lightspeed and Index Ventures, and senior leadership at Google DeepMind and Meta GenAI.
Our founding team brings backgrounds from Jane Street, Meta, Citadel Securities, Google, Goldman Sachs, Morgan Stanley, Silver Lake, and Palantir.
Why Apply
Massive Opportunity: We are growing incredibly fast and have reached millions in monthly revenue in < 12 months. The foundation model labs are scaling faster than any technology companies in history. We sit at the center of that growth, providing the data and infrastructure needed to push the frontier forward
Founding Role: Own the job from day one
Competitive Salary + Meaningful Equity in a fast-scaling company
High Caliber Team: Work alongside a founding team that left firms like Citadel Securities, Jane Street, Meta, Palantir, Goldman Sachs, and Morgan Stanley. Join for a front row seat at the frontier with the most talent-dense team you've ever worked with
Responsibilities
Hiring Pipeline Ownership: Own recruiting end-to-end, from sourcing and top-of-funnel outreach to coordinating interviews and work trials, managing candidate relationships, and managing external recruiters. You'll be the operational force that keeps hiring moving quickly and without gaps.
Executive Assistant Management: Directly manage our EA, ensuring calendars, travel, scheduling, and day-to-day logistics for the founding team are handled seamlessly.
Admin & Office Operations: Own the company's administrative infrastructure: financials (payroll, expense tracking, vendor payments, invoicing), real estate and lease management, office setup, and any other operational foundations that keep the business running smoothly.
Operations & Sales Support: Step in wherever the founding team needs support, whether that's prepping materials for customer calls, tracking deal progress, drafting contracts, or solving cross-functional bottlenecks as they arise.
Founder Support & Strategic Execution: Serve as the right hand to the founding team across whatever the company needs most. This includes managing calendars, running executive meetings, driving decision-making, owning high-priority cross-functional projects, drafting internal memos and external communications, building and refining company operating cadences, monitoring core business metrics, identifying and eliminating operational bottlenecks, and acting as organizational glue as the team scales. If it matters to the company and doesn't have a clear owner, it's yours.
