AI-Specific Product Management

• Own the data strategy for model training and improvement, including data acquisition, annotation, and quality assurance processes.
• Define and maintain AI evaluation frameworks and benchmarks for model performance (e.g., intent recognition accuracy, summary quality, scam detection precision/recall).
• Design user experiences that account for AI's non-deterministic nature, including error handling, confidence thresholds, and fallback mechanisms.
• Define the scope and safeguards for agentic AI capabilities, including user trust models and permission frameworks for AI actions taken on behalf of users.
• Work with engineers to establish testing and evaluation protocols specific to LLM-based products.

User Experience & Market Research

• Work directly with UX/UI designers to craft an intuitive user experience for voice-based interactions.
• Design voice personalization, emotional intelligence features, and sensitive onboarding flows like voice cloning consent.
• Conduct comprehensive market research to understand target audience pain points and existing solutions.

• Analyze user feedback and usage data to inform product decisions and prioritize feature enhancements.

Stakeholder Management & Business Impact

• Serve as the primary liaison between the engineering team and stakeholders, e.g., interim C-levels, CX teams, etc.
• Collaborate with engineering teams to define, track, and analyze success metrics and KPIs that measure product success and connect to stakeholder value.
• Track metrics across user engagement, AI effectiveness, and tangible business impact, such as reduction in user-reported scam calls, increased engagement with telco-specific benefits, or direct impact on customer churn.
