About the Role

Mercor is building realistic, high-fidelity simulated environments to evaluate and train AI models on real-world procurement workflows for a leading spend-management technology company. We're looking for senior procurement and vendor-management professionals to author and validate tasks that mirror how procurement teams actually vet new vendors and review contract renewals.

Key Responsibilities

• Review simulated new-vendor intake requests, benchmarking price and contract terms against realistic company reference data
• Consolidate multi-lens reviews (finance, legal, security, IT) into a well-reasoned final approval recommendation
• Author step-level rubrics and golden responses that capture how an experienced procurement lead would judge a request or renewal
• Audit simulated company environments for realism and unintended contradictions before tasks open

Ideal Qualifications

• 8+ years of professional experience in procurement, spend operations, or vendor management, with hands‑on experience running real vendor requests and renewals
• Sourced from mature procurement functions at companies with formal vendor‑review processes
• Strong written communication skills; comfortable producing structured, rubric‑style feedback

Nice to Have

• Experience with modern spend‑management or e‑procurement platforms
• Prior task‑writing, rubric‑authoring, or AI‑training data experience
