Anonymization Writer

Overview

Mercor is hiring writers on a contract basis for Project Sisyphus, a PII anonymization program. This is a fully remote, long-running internal project for United States-based candidates. The work centers on reviewing business documents and structured records, identifying what counts as personal information, catching missed PII, and grouping related entities so people and organizations are handled consistently. Reviewers will check submitted work before it ships.

Projects may be extended, shortened, or ended early depending on needs and performance. The role is asynchronous and can be completed on your own schedule.

What You'll Do

• Confirm, reject, add, and correctly type PII across tasks with dozens to hundreds of individual decisions.
• Group related entities such as people, organizations, and contact details into the correct clusters.
• Find personal information that automated detection missed, while avoiding labels on information that is not personal.
• Apply guidelines that may change several times per week, using the current version in force on the day you work.
• Act on reviewer feedback quickly and apply it across future tasks, not just the specific item reviewed.
• Work asynchronously with a distributed team and raise ambiguous cases in the project channel instead of guessing.

What We're Looking For

• Availability to commit 30+ hours per week, with this as your main project.
• Prior experience with AI data work such as labeling, rating AI responses, or QA/review of AI outputs.
• Strong attention to detail and patience for long, repetitive material.
• Background in detail-heavy work such as operations, accounting, editing, design, compliance, or account management.
• Comfort working with frequently changing rules and checking the current guideline before relying on memory.
• Ability to take feedback well and adjust quickly.
• Ability to work entirely without AI assistance on task data.

Preferred Qualifications

• Familiarity with PII, privacy, or data-protection concepts, including direct versus indirect identification.
• Experience with medical record de-identification, copy-editing, or paralegal work.
• Experience reading structured business data such as CRM, ticketing, email, or accounting exports.

Contract and Payment Terms

• You will be engaged as an independent contractor.
• Payments are made weekly on Stripe or Wise based on services rendered.
• The role cannot support H1-B or STEM OPT candidates at this time.
