In this role, you'll apply your expertise to help train next-generation AI systems. Your work will shape how models learn, reason, and perform through high-quality, real-world input. No prior experience in AI is required — your domain knowledge is what matters. This opportunity is ideal for expert editors who have demonstrated excellence working on published books, especially those with experience editing award-winning or bestselling titles. A strong commitment to both written and verbal communication is highly valued, as contributors will be collaborating in a fully remote environment with a focus on impactful editorial contributions.

• Provide detailed editorial feedback and perform advanced line editing, copyediting, and content restructuring as needed.
• Identify inconsistencies, gaps, or opportunities for improvement in plot, character development, and thematic continuity.
• Contribute to the creation of editorial guidelines and best practices to inform AI model development.
• Draft, revise, and polish editorial commentary, ensuring feedback is constructive, actionable, and aligned with high industry standards.
• Collaborate with project stakeholders by participating in written and verbal discussions to communicate edits and recommendations effectively.
• Support ongoing quality control by reviewing and refining AI-generated editorial work for accuracy and style.

Preferred Qualifications

• Extensive experience editing published books for recognized publishing houses or prominent authors.
• Editorial leadership on books that have achieved notable recognition (e.g., New York Times bestsellers or award-winning titles) is a significant plus.
• Exceptional command of the English language, grammar, and literary style.
• Proven ability to deliver incisive, nuanced editorial feedback across genres and formats.
• Strong collaboration skills with a passion for both written and verbal communication.
• Comfort working in a remote, tech-enabled environment and adapting to evolving project needs.
