About the Opportunity

This opportunity is for experienced Product Managers and Product Owners to contribute to an advanced project focused on AI system development and evaluation.

In this role, you'll apply your product expertise to help train next-generation AI systems through high-quality, real-world input. You'll evaluate AI-generated content and assess how effectively it meets product, audience, and communication requirements.

No prior AI experience is required — your product management and product ownership expertise is what matters.

This is strictly an evaluation and analysis opportunity. The engagement does not involve roadmap ownership, delivery management, sprint facilitation, stakeholder leadership, or programme governance.

Candidates whose primary backgrounds are in project management, programme management, delivery management, or Scrum leadership are not the intended fit for this engagement.

Key Responsibilities

• Assess and compare AI-generated responses to a variety of product and business writing prompts.
• Evaluate content including product specifications, release notes, user-facing copy, and stakeholder updates.
• Score responses based on clarity, tone, instruction adherence, accuracy, and usefulness for the intended audience.
• Write detailed evaluation rationales explaining the reasoning behind each assessment.
• Determine whether generated content appropriately addresses prompt requirements and audience needs.
• Identify cases where fluent or well-written content fails to answer the underlying question or is unsuitable for its intended users.
• Detect factual inaccuracies, inconsistencies, omissions, and constraint violations.
• Collaborate virtually and asynchronously with project managers and reviewers to maintain consistency and quality across evaluations.

Required Qualifications

• Professional experience as a Product Manager or certified Product Owner with a strong record in cross-functional product development.
• Native-level English fluency and exceptional written communication skills.
• Extensive experience creating and evaluating product specifications, PRDs, acceptance criteria, release notes, or decision documents.
• Ability to evaluate whether content is appropriately tailored for executives, technical stakeholders, and end users.
• Strong ability to provide actionable written feedback on technical and user-facing documentation.
• Exceptional attention to detail and critical analysis skills.
• Ability to work independently while consistently meeting remote project deadlines.
• Strong product judgment and content evaluation skills.

Preferred Qualifications

• Familiarity with AI model evaluation, RLHF, or data annotation.
• Experience evaluating AI-generated or technology-related content.
• Strong understanding of product development processes and documentation standards.
• Experience working in cross-functional and distributed product teams.
• Ability to assess complex content from both technical and user perspectives.

Compensation

• Competitive compensation of $90–$140/hour.
• Flexible, remote project-based work.
• Opportunity to apply professional product management and product ownership expertise to next-generation AI systems.
