  • Develop Prompt Libraries: Create scalable, reusable prompt templates and documentation for internal teams, democratizing AI capabilities across the organization.
  • Collaborate with Data Science: Partner with ML engineers to align prompt strategies with model fine-tuning objectives and dataset curation.
  • Content Strategy & Tone: Curate the voice and persona of AI outputs to match brand standards, ensuring consistency across all customer-facing AI interactions.
  • Feedback Loop Management: Analyze user interactions and feedback to continuously iterate and improve prompt logic.

Qualifications
