The company operates a platform where millions of domain experts train frontier AI models, and is building infrastructure for Fortune 500 companies to capture and translate expertise into AI agents. Mercor is a profitable Series C company valued at $10 billion. As Chief of Staff to the Head of Product, you will be the operational backbone of the product organization, which spans Marketplace, Studio (annotation), RL Environments, and the Eval Platform. You'll work directly with the Head of Product and cross-functional leadership to transform a fast-moving, multi-team org into a coherent, predictable machine. Key responsibilities include: - Establish and drive planning and review cadences across the product org; prepare leadership meetings end-to-end with agendas, pre-reads, framing data, and decision follow-through - Conduct competitive intelligence - Support hiring efforts - Standardize roadmaps across product areas to enable leadership comparison, sequencing, and resource allocation - Own monthly product-offering updates to customers, coordinating inputs and ensuring consistent voice - Build connective tissue between Product and adjacent functions (product marketing, developer relations) to ensure launches and roadmaps integrate cleanly - Support product recruiting, own PM onboarding, and coordinate performance reviews with consistent timelines and calibration - Take on highest-leverage cross-cutting initiatives that lack a natural owner and drive them to completion - Shape Mercor's customer-facing product narrative and drive deeper relationships across the AI ecosystem You'll balance long-term operating strategy with rapid execution, owning work that falls between teams and directly shaping product org performance. Requirements: - 2+ years in a chief-of-staff, product-ops, strategy & ops, or PM role; exposure to fast-scaling teams preferred - Strong product intuition and ability to pressure-test decisions on merit - High ownership mentality with full accountability for outcomes - Ability to build lightweight processes that create clarity without bureaucracy - Excellent structured communication skills; ability to write crisp, exec-ready docs and turn ambiguity into clear plans - Cross-functional influence and ability to get things done without formal authority - Sound judgment and discretion in handling sensitive information and competing priorities - Comfort with both rigorous analysis and strategic narrative framing
