• Develop secure integration layers between AI products and enterprise platforms such as CRM, operational, and policy systems.
• Implement observability, monitoring, logging, and feedback loops to continuously improve AI performance in production.
• Own the full software lifecycle including architecture, development, testing, CI/CD, deployment, and production support.
• Collaborate closely with Product, AI Engineering, Business, and Leadership teams to shape product direction.
