  • Exceptional attention to detail and ability to identify subtle errors, ambiguity, inconsistencies, and meaning drift.

  • Excellent written and verbal communication skills.

  • Ability to clearly explain corrections, reasoning, and language decisions.

  • Strong analytical and critical-thinking skills.

  • Ability to apply style guides and maintain consistency across different content types and registers.

  • Ability to work independently and reliably in a remote environment across time zones.

Preferred Qualifications

  • Professional proficiency in at least one additional language.

  • Previous experience in AI data training, annotation, editorial QA, localization QA, or professional copyediting.

  • Experience evaluating AI-generated content or training data.

  • Strong hands-on experience using ChatGPT, Gemini, Perplexity, or similar AI tools.
