• Build and refine AI agents within collaborative squads, including orchestration, tool usage, and context-memory management.
• Define response-quality criteria and conduct structured, iterative testing to evaluate and improve AI-generated outputs.
• Implement guardrails, out-of-scope response handling, and mitigation strategies for risks such as prompt injection.
• Establish and document prompt engineering standards, versioning practices, reusable patterns, and best practices for broader team adoption.
• Collaborate with technical teams to publish and maintain solutions through existing Git and CI/CD workflows.
• Continuously investigate new AI platforms and techniques and adapt quickly to proprietary tools and evolving project requirements.
