Marketing Expert [80-150/hr] 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 robust 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
