Marketing Expert

1. Role Overview

Mercor is partnering with a leading AI research organization to engage experienced marketing professionals for a project focused on evaluating how well AI systems perform real-world marketing work. Rather than producing deliverables yourself, you will define what excellent work looks like: designing task-specific grading criteria and scoring completed work samples with rigorous, well-reasoned written justifications.

2. Key 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

3. Ideal Qualifications

• 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 role

4. Application Process

• Submit your resume or relevant professional background to get started

• Qualified applicants may be asked to complete a brief assessment or submit additional information

We consider all qualified applicants without regard to legally protected characteristics and provide reasonable accommodations upon request.
