• Design and optimize MLOps pipelines using Databricks and cloud-native stacks (AWS Fargate, Bedrock, ECS), integrated with our newly built data platform; drive automation, monitoring, and CI/CD practices across the ML lifecycle.
• Review and validate model code, pull requests, and deployment flows, ensuring technical excellence, reproducibility, and scalability across the AI team.
• Define and align data exchange protocols and architecture with DevOps, Data Engineering, and Backend teams.
• Partner with Product Analytics to track KPIs, monitor model performance, and measure the impact of AI solutions on CloudPay products and client operations.
• Operate within cross-functional, multinational teams, with autonomy to experiment, innovate, and test new approaches while observing tangible effects on CloudPay clients and operations.
• Stay ahead of AI trends, tools, and infrastructure innovations to guide long-term strategy and maintain CloudPay's competitive edge.
