• Review generated help articles and response templates for correctness and ease of use.
• Label the sentiment and empathy of responses, noting when language sounds unprofessional or robotic.

• Experience in a high-volume customer support, technical support, or client success role.
• Strong written English, with the ability to adjust clarity and empathy for different customer situations.
• Skill in calming difficult interactions and explaining technical or billing troubleshooting step by step.
• Fast, accurate typing and the ability to find answers across multiple information sources.
• Careful attention to factual accuracy, logic, and tone.
• A Pay Pal account to receive task payments.

• Additional language skills, especially for reviewing translations and localized customer support.
