• Support application releases and coordinate deployments across environments.
• Implement logging/monitoring using Prometheus, Grafana, Datadog, Splunk, orCloudWatch.
• Participate in incident response, troubleshooting, on-call rotation, andpost-incident RCA.
• Perform system performance tuning, patching, capacity planning, andoptimization.
• Improve system reliability through automation, redundancy, and engineeringbest practices.
• Implement and maintain IaC using Terraform or CloudFormation.
• Automate provisioning, configuration, and environment setup using scripting(Python, Bash, Go).
• Develop reusable automation modules, templates, pipelines, and cloudengineering patterns.
• Build, deploy, and manage containerized applications using Docker.
• Operate and optimize Kubernetes clusters (EKS or on‑prem).
• Implement autoscaling, service mesh, pod security, and workload monitoring.
• Develop automation services, internal tooling, and platform utilities usingCore Java, Spring Boot, Quartz, and Erlang.
• Build wrappers/services for IBM MQ and RabbitMQ messaging flows.
• Create schedulers, orchestration components, and internal micro‑services foroperational tasks.
• Write integrations, connectors, and event-driven components forinfra-automation.
