• Build and maintain enterprise-grade AI platforms capable of supporting high-volume production workloads.
• Optimize performance, reliability, security, and scalability of AI services.

AI Operations & Delivery

• Establish and maintain CI/CD pipelines for AI-enabled applications and services.
• Implement MLOps best practices for deployment, monitoring, testing, and lifecycle management of AI solutions.
• Support model integration, version management, governance, and operational excellence.
• Monitor production environments and continuously improve platform performance and user experience.

Innovation & Collaboration

• Evaluate emerging AI technologies and identify opportunities for enterprise adoption.
• Collaborate with product managers, software engineers, data scientists, UX teams, and business stakeholders.
• Contribute to technical architecture decisions and AI engineering best practices.
• Drive continuous improvement across AI development methodologies and delivery frameworks.
