Mercor Enterprise brings this same infrastructure to Fortune 500 companies: helping companies capture how their best people actually work, translating that expertise directly back into agents.   Mercor is creating a new category of work where expertise powers AI advancement. Achieving this requires an ambitious, fast-paced and deeply committed team. You’ll work alongside researchers, operators, and AI companies at the forefront of shaping the systems that are redefining society. Mercor is a profitable Series C company valued at $10 billion. We work in-person five days a week in our San Francisco, NYC, or London offices. ABOUT THE ROLE Silicon Valley’s leading AI companies partner with Mercor to scale high-quality data operations. As an SPL, you will: - Drive the tactical execution of multi-million-dollar projects. - Build deep client relationships with researchers at top AI labs. - Orchestrate the work of 1,000+ contributors. - Ensure flawless operational execution under demanding timelines. This is a hands-on operations role for candidates excited by process optimization, rapid iteration, and high-intensity problem solving. We're an early-stage startup that operates with intensity. That means occasionally being responsive on weekends and always holding a high bar for output. The upside — performance incentives, career trajectory, and meaningful equity — reflects that. CORE RESPONSIBILITIES OPERATIONAL EXCELLENCE - Design and manage end-to-end data pipelines, from customer specifications to final delivery. - Diagnose bottlenecks, restructure workflows, and implement solutions that improve quality, throughput, and cost-efficiency. - Examples include: creating incentive systems, re-sequencing workflows, refining instructions, and scaling review processes. CUSTOMER RELATIONSHIPS - Act as the primary point of contact for leading AI labs. - Deliver clear, consistent reporting and proactively anticipate client needs. - Build long-term trust and identify opportunities for expansion. LARGE-SCALE COORDINATION - Manage 1,000+ distributed contributors in Slack-based workspaces. - Source, vet, train, and performance-manage domain experts. - Maintain high execution standards across all stages of production. QUALITY REPORTING - Run daily internal syncs (“war rooms”) to stay ahead of issues. - Provide regular, transparent progress updates to customers. WHAT WE’RE LOOKING FOR - Experience: Background in consulting, finance, startups, or other operationally intense environments. - Skills: Strong analytical and communication abilities; proven track record of managing complex projects. - Customer-Facing Experience: Comfortable working directly with high-profile clients. - Mindset: Excited by “gritty” process optimization and large-scale execution. KEY FACTS - SPLs generate $10M+ in project revenue annually. - In-office Mon–Fri - Customer requests are high-pressure and time-sensitive (e.g., onboarding 1,000 contributors in 3 days, delivering 10+ hours of quality data per contributor within 48 hours). - The role is explicitly operations-focused—not strategy, product, or GTM. GROWTH PATH - SPLs begin as individual contributors, running projects end-to-end. - High performers may advance to Senior SPL (SSPL) roles, managing multiple projects and teams of SPLs.
