Experienced marketing professionals to evaluate how well AI systems perform real-world marketing work and define what excellent work looks like: designing task‑specific grading criteria and scoring completed work samples with rigorous, well‑reasoned written justifications.

Role Responsibilities

• Design precise, task‑specific grading criteria for real‑world marketing deliverables (creative briefs, campaign concepts and decks, brand positioning and messaging frameworks, ad copy and scripts, integrated campaign plans, client‑ready presentations)
• Score AI‑generated and human work samples against those criteria, with detailed written justifications for every score
• Apply consistent, evidence‑based judgment so that scores are reproducible and defensible
• Incorporate structured feedback from senior reviewers and iterate quickly on your work

Good Candidature

• 5+ years of professional experience in marketing or advertising
• Background as a creative director, account lead, or brand strategist at top‑tier global creative agencies, or in senior brand marketing roles at leading consumer companies
• Deep fluency in the day‑to‑day craft: writing and evaluating creative briefs, campaign development across channels, brand positioning and messaging, and judging creative work against a brief and a business objective
• Exceptionally strong written communication, with the ability to explain exactly why a piece of work does or does not meet the bar
• Detail‑oriented, consistent, and comfortable having your judgment reviewed and calibrated against peers
• Prior experience with AI training, evaluation, or human‑data projects is a strong plus
• No specialized media‑planning or measurement background is required for this
