Obsidian; Dallas (TX); On-site; USD 55,000 - 110,000; Full time

Job summary

Mercor is running a short, structured evaluation pilot to measure how frontier AI models perform on realistic professional work — and how experienced practitioners judge that work. We are hiring 25 experts across four business domains. Each expert completes one task, then evaluates five model attempts at that same task.

This is a one-time study, not ongoing production work. No rubric and no golden answer are provided; professional judgment is the measure.

Qualifications

• 5+ years of hands-on professional experience in Admin / Business Operations, Marketing, Human Resources, or Accounting.
• Currently or recently practicing, so you can judge the work the way a working professional would.
• Able to write a clear, specific, evidence-grounded rationale for a judgment.
• Reliable within a short turnaround window.

Responsibilities

• Sign an NDA before receiving any materials.
• Solve one realistic, domain-specific task using the source files provided.
• Review five model-generated outputs for that task. Rank them 1–5 with no ties, score each 0–100, and write evidence-based rationales that cite specific parts of the output.
• Provide structured feedback on the task itself and on the study design.

Job description

Role Overview

Mercor is running a short, structured evaluation pilot to measure how frontier AI models perform on realistic professional work — and how experienced practitioners judge that work. We are hiring 25 experts across four business domains. Each expert completes one task, then evaluates five model attempts at that same task. This is a one-time study, not ongoing production work.

What You'll Do

• Sign an NDA before receiving any materials.
• Solve one realistic, domain-specific task using the source files provided.
• Review five model-generated outputs for that task. Rank them 1–5 with no ties, score each 0–100, and write evidence-based rationales that cite specific parts of the output.
• Provide structured feedback on the task itself and on the study design.

Time Commitment

Up to 13 hours total: 3–10 hours to solve the task, approximately 2 hours to rank and score the five outputs, and approximately 1 hour to provide feedback.

Study Conditions

• No rubric and no golden answer are provided. Your professional judgment is the measurement.
• Use of LLMs or other AI assistants is prohibited at every stage — solving, ranking, scoring, and writing rationales.

Domains we are focused on

• Admin / Business Operations
• Marketing
• Human Resources
• Accounting

Who We're Looking For

• 5+ years of hands‑on professional experience in one of the four domains above.
• Currently or recently practicing, so you can judge the work the way a working professional would.
• Able to write a clear, specific, evidence‑grounded rationale for a judgment.
• Reliable within a short turnaround window.

Eligibility Restriction

You are not eligible for this pilot if you have worked on Project Alchemy in any capacity — task author, reviewer, world expert, or anyone who has had access to its source world data. Prior exposure to that material would invalidate the study.
