• Deploy and operationalize machine learning models using AWS services, with an emphasis on Amazon SageMaker.

• Deploy and support containerized workloads within AWS-based machine learning environments.
• Create automated deployment, testing, monitoring, and promotion processes across multiple environments.
• Collaborate with architects and engineering teams to improve platform reliability, scalability, and operational maturity.
• Implement monitoring, alerting, logging, and operational best practices to support production systems.
• Mentor junior engineers and promote engineering best practices across the team.
• Partner with cross-functional teams including platform engineering, infrastructure, security, and business stakeholders.

• Experience deploying containerized applications in cloud environments.
• Hands-on Infrastructure as Code experience using Terraform or AWS CloudFormation.
• Strong AWS experience deploying production workloads.
• Experience supporting the machine learning deployment lifecycle, including model deployment, inference pipelines, monitoring, and operational support.
