Roles and Responsibilities

• Take overall responsibility for the setup, configuration, and architecture of Docker and Kubernetes environments.
• Design, deploy, configure, and maintain highly available and scalable OpenShift / Kubernetes clusters across various environments (on-premise / cloud).
• Perform regular upgrades, patching, and security hardening of Kubernetes / OpenShift clusters and underlying infrastructure to ensure operational integrity and compliance.
• Manage cluster resources, network policies, storage classes (CSI), and role-based access control (RBAC).
• Implement and manage Kubernetes Operators for automated application lifecycle management from an infrastructure perspective.
• Configure, maintain, and provide advanced support for large-scale Docker-based environments using Kubernetes.
• Troubleshoot and swiftly resolve complex and critical issues within the Docker and Kubernetes ecosystem.
• Ensure robust operational aspects, including comprehensive monitoring, detailed reporting, and reliable backup solutions for both Docker hosts and associated images / containers.
• Administer and optimize our CI / CD toolchain, including GitHub for source code management and GitOps workflows, Jenkins for build and deployment automation, and JFrog Artifactory / Xray for artifact management and security scanning.
• Maintain robust Jenkins pipelines (declarative / scripted) to support automated application builds, testing, and deployments to Kubernetes / OpenShift.
• Develop and maintain automated processes, tools, and clear documentation in support of Docker and Kubernetes operations.
• Implement Infrastructure as Code (IaC) principles using tools like Terraform or Ansible for cluster provisioning and configuration management.
• Automate routine operational tasks, monitoring, and self-healing capabilities within the container platform.
• Collaborate with development teams to optimize microservices deployments, scaling strategies, and resource utilization on the Kubernetes platform.
• Provide expert guidance on containerization best practices, image optimization, and runtime configurations for microservices to ensure platform stability.
• Troubleshoot complex issues related to microservices connectivity, performance, and stability within the containerized environment from an infrastructure standpoint.
• Implement and manage comprehensive monitoring solutions (e.g., Prometheus, Grafana) for cluster health, application performance, and resource utilization.
• Configure centralized logging solutions (e.g., ELK stack, Splunk) to collect, analyze, and visualize logs from containers and cluster components.
• Define and manage alerting mechanisms to ensure proactive identification and resolution of issues.
• Enforce security best practices for container images, registries, and Kubernetes deployments.
• Implement network segmentation and policies to secure inter-service communication within the platform.
• Manage secrets and sensitive data securely within the Kubernetes environment (e.g., using Kubernetes Secrets, Vault).
• Ensure the container platform and associated processes adhere to BFSI regulatory requirements and internal security policies (e.g., PCI DSS, SOC2, data residency).
• Conduct regular security audits and vulnerability assessments of the container platform.
• Work closely with development, operations, and security teams to ensure seamless integration and operational excellence of the platform.
• Utilize Jira for agile project management and issue tracking related to platform tasks.
• Create and maintain comprehensive documentation for cluster architecture, operational procedures, and troubleshooting guides.
• Deeply engage with stakeholders to understand their architecture and operations, continuously working to improve their overall Kubernetes support experience.
