Job SummaryWe are looking for an experienced OpenShift Level 2 Engineer to support the day-to-day operations of the One Bank Container Service (OBCS).

The successful candidate will be responsible for OpenShift cluster patching, platform releases, automation execution and operational troubleshooting using Ansible and Tekton. The role requires advanced OpenShift expertise, strong troubleshooting capabilities and the ability to coordinate directly with application owners and customer teams to ensure platform stability and service availability.

This is a hands-on engineering role requiring independent diagnosis and resolution of operational issues, rather than basic monitoring or ticket management.

Key Responsibilities

- Plan and execute OpenShift cluster patching and version upgrades.
- Monitor cluster health, node status, Cluster Operators and Machine Config Pools (MCPs).
- Execute approved Ansible playbooks and Tekton pipelines for platform patching and releases.
- Troubleshoot node drains, pod scheduling issues, unhealthy nodes and failed cluster updates.
- Manage OBCS releases across environments, ensuring approved versions and configurations are deployed.
- Investigate Ansible job failures and Tekton pipeline execution issues.
- Manage ServiceNow change requests, including implementation plans, risk assessments, approvals and closure evidence.
- Coordinate maintenance windows, release readiness and validation with application owners and customer teams.
- Troubleshoot Pod Disruption Budget (PDB) issues and resolve workload availability blockers.
- Maintain automation scripts, Ansible roles,



Tekton tasks and operational runbooks.
- Support incident and problem management, providing detailed technical escalations to L3 teams.
- Ensure changes follow approved procedures, security controls and change-management processes.

Mandatory Technical SkillsOpenShift / Kubernetes
- Robust hands-on experience with OpenShift 4 and Kubernetes administration.
- OpenShift cluster upgrades, patching and node lifecycle management.
- Cluster Version Operator (CVO), Machine Config Operator (MCO) and Machine Config Pools.
- Troubleshooting Deployments, StatefulSets, pods, scheduling and cluster operators.
- Strong command-line experience using oc.

Ansible
- Hands-on experience with Ansible playbooks, roles, inventories and variables.
- Experience with Ansible Automation Platform.
- Troubleshooting automation failures and understanding idempotency and safe execution.

Tekton
- Experience with Tekton Tasks, Pipelines, TaskRuns and PipelineRuns.
- Troubleshooting pipeline failures, execution logs, parameters and service accounts.

Pod Disruption Budgets (PDB)
- Strong understanding of PDB configurations, eviction behaviour and workload availability.
- Experience troubleshooting blocked node drains and workload disruption issues.




- Ability to coordinate with application owners to resolve PDB-related blockers safely.

Additional Technical Skills
- Strong Linux administration and troubleshooting.
- Understanding of DNS, ingress, load balancing and network policies.
- Knowledge of persistent volumes, storage attachment and Kubernetes networking.
- Experience with Git, YAML and configuration-as-code.
- ServiceNow change and incident management experience.
- Understanding of RBAC, least-privilege access and operational security.

Required Experience and Competencies
- Strong operational engineering experience in enterprise OpenShift environments.
- Ability to independently diagnose complex platform and workload issues.
- Experience managing production patching and release activities.
- Strong customer-facing communication and stakeholder coordination skills.
- Ability to assess operational risks and make safe implementation decisions.
- Experience maintaining technical documentation and operational runbooks.

What We're Looking For
- An experienced OpenShift engineer with strong hands-on operational capabilities.
- Someone who can independently manage patching and release activities.
- Strong Ansible and Tekton automation experience.
- Practical experience resolving PDB and node-drain issues.
- A proactive engineer who understands production change management and platform availability.
- Note: This role requires advanced OpenShift operational expertise. Basic Kubernetes monitoring, L1 support or ticket-routing experience alone will not be sufficient.
