Key Responsibilities

1. Infrastructure Automation and Environment Readiness

• Define environment-readiness patterns, Ansible playbook and runbook standards, request workflows and platform handover criteria in collaboration with Infrastructure and DevOps teams.
• Develop reusable environment-readiness templates and repeatable configuration tasks supported by Ansible.
• Document runner, platform, environment and dependency requirements necessary for squad and integration delivery.
• Implement environment-readiness patterns and Ansible runbooks across squad and integration environments.
• Address handover gaps by documenting criteria, responsible owners, dependencies, approval processes and service-readiness evidence.

2. Automation Governance and Performance Monitoring

• Maintain tests, documentation, safe change practices and version control for automation assets.
• Monitor environment-readiness lead time, self-service fulfilment, handover delays and adoption of standard patterns.
• Ensure automation scripts, playbooks, runbooks and templates are properly committed, reviewed and documented.
• Ensure shared-platform automation and remediation evidence is available for governance reviews.

3. Container and Shared-Platform Management

• Maintain inventories of Docker and shared platforms, lifecycle risks, Kubernetes migration candidates, Ansible automation opportunities and infrastructure dependencies.
• Develop container pilot support, operational runbooks and priority platform upgrade or recovery patterns.
• Support Kubernetes/Rancher modernisation and Docker transitions for priority platforms.
• Promote the reuse of environment-readiness patterns across technology squads and supported integration initiatives.

4. Platform Migration and Modernisation

• Execute approved migration activities, capacity-change coordination, Ansible remediation tasks and shared-platform improvements.
• Validate migration targets, HA/DR consistency, runbook evidence and future upgrade schedules.
• Contribute to platform modernisation standards, migration lessons learned and reusable operational procedures.

5. Infrastructure Resilience and Troubleshooting

• Support capacity, performance, Disaster Recovery (DR), Business Continuity Planning (BCP) and resilience validation with Site Reliability Engineering (SRE) and Infrastructure teams.
• Troubleshoot automation, configuration, lifecycle, migration and shared-service issues affecting delivery teams.
• Coordinate platform upgrades and recovery activities to improve operational reliability.
