Responsibilities

CI/CD &Deployment Automation

• Configure and maintain CI/CDpipelines, incorporating streamlined change management and release processes.
• Develop scripts and automationtools to support software build, integration, and deployment across development and production environments.
• Automate the configurationmanagement of development, QA, and production workloads.
• Develop automation andprocesses to enable teams to deploy, manage, scale, and monitor applications indata centers and cloud environments.
• Defineand enforce branching strategies and code review gates across teams. (plus point)
• Integrate automated code quality checks and test coverage thresholds as mandatory pipeline stages. (plus point)
• Manageand maintain artifact repositories for build artefact versioning and dependency management. (plus point)

GitOps & Release Management

• Implement GitOps workflows for declarative, Git-driven continuous delivery to Kubernetes clusters.
• Manage release versioning, changelogs, and rollback strategies to ensure controlledand auditable deployments.
• Coordinate blue-green deployments, canary releases, and feature flag rollouts to reduce deployment risk.

Infrastructure asCode & Automation

• Implement Infrastructure asCode (IaC) pipelines to reduce manual configuration drift.
• Build self-healing systems with automated remediation for common alerts.
• Design, build, optimize, and monitor automation systems to identify bottlenecks and maximize service availability.
• Provision virtual machines, databases, containers, and licenses for development teams.
• Implement configuration management systems for business continuity and automate disaster recovery measures.
• Enforce IaC code reviews, linting, and policy-as-code to prevent misconfigurations.

Platform & Application Support

• Troubleshoot and resolve system and application issues across platforms, including participating in on-call escalations for critical incidents.
• Take ownership of end-to-end infrastructure and security solutions across the organization.
• Deploy and manage monitoring tools to track infrastructure performance, utilization, and health.

• Build and maintain internal developer platforms (IDPs) or self-service tooling to improve developer productivity and reduce platform team toil.

Security (DevSecOps)

• Implement security practices aligned with industry standards to protect organizational data and infrastructure.
• Plan, implement, and monitor system security architecture, including threat and risk assessments.
• Perform security checks such as vulnerability assessments and system hardening.
• Apply secure configurations and security controls for infrastructure and applications.

• Integrate SAST (Static Application Security Testing) and DAST (Dynamic Application Security Testing) tools directly into CI/CD pipelines.
• Implement container image scanning and enforce policies to block deployment of images with critical vulnerabilities.
• Manage secrets securely using dedicated secret management tools — no secrets in code or config files.
• Apply shift-left security principles, embedding security checks as early as the code commit stage.

Collaboration & Enablement

• Serve as the bridge between application teams and infrastructure teams, enabling self-service for troubleshooting.
• Train agency teams on operational best practices and tool adoption (e.g., ITSM workflows, DevOps pipelines).
• Champion DevOps culture across engineering squads through workshops, documentation, and internal community of practice sessions.
