• Partner with Content Design, Product, and Engineering teams to translate knowledge architecture (taxonomy, content models, decision tables, and policy relationships) into technical systems
• Stand up and configure a headless CMS platform that implements the organization's knowledge operating model, translating content models, taxonomy, and governance structures defined by Content Design into scalable technical systems
• Develop APIs and services that expose structured knowledge to internal tools, AI assistants, and future product experiences
• Build and maintain integrations between knowledge storage systems and AI tooling, including retrieval pipelines and experimentation with RAG-based architectures
• Prototype using lightweight tooling (e.g., Git-based content repositories, markdown workflows, and developer-friendly authoring environments)
• Collaborate with engineers and designers to identify opportunities where structured knowledge can improve product development workflows and AI capabilities
• Evaluate and recommend technology approaches for knowledge storage and delivery (e.g., headless CMS platforms, structured content repositories, search infrastructure)
• Establish scalable patterns for content versioning, governance workflows, and structured metadata management
• Work with cross-functional stakeholders to ensure the system supports internal enablement needs such as SOPs, policies, decision trees, and operational guidance
