- Mission
- Design, deploy, and maintain Red Hat OpenShift platforms
- Adapt and optimize OpenShift clusters (filesystem management, access control, quotas, policies) on underlying Unix/Linux systems.
- Install, migrate, and operate Unix/Linux environments according to our standards and processes.
- Plan and manage system storage and related capacity (including persistence of OpenShift volumes).
- Ensure security, resilience, and compliance across environments.
- Participate in on-call rotations.
Challenges
- Adapt to heterogeneous environments (AIX/Solaris/RHEL, virtualization) and existing processes.
- Align Unix/Linux operations practices with container, Kubernetes, and OpenShift paradigms.
- Support application migrations to OpenShift with minimal impact, while meeting financial-sector security requirements.
Main responsibilities
General competencies
- Knowledge of major Unix/Linux distributions: IBM AIX, Red Hat Enterprise Linux (RHEL), Solaris.
Proven experience deploying and operating OpenShift or Kubernetes in production.
- Understanding of storage and network technologies: memory, disk arrays, NAS/SAN, networking (TCP/IP, VLAN, load balancing).
- Understanding of database concepts: maintenance, recovery, failover, high availability.
- Understanding of routine maintenance, recovery, and handling failover of a Database
Familiarity with at least one enterprise backup solution (e.g., NetBackup, Commvault, Veeam).
Specific competencies
- Install, configure, and maintain Red Hat OpenShift clusters (IPI/UPI, bare metal/virtualized/cloud).
- Mastery of Kubernetes/OpenShift concepts: projects, routes, services, deployments, statefulsets, operators, CRD, RBAC, SCC, NetworkPolicy.
- OpenShift lifecycle management: controlled upgrades, patches, channels, image mirroring, oc CLI.
- Security and compliance:
- Configuration of RBAC, SCC, PSa/PSP equivalents, secrets, encryption.
- OIDC/SAML integration with IdPs (e.g., Keycloak, Azure AD).
- Policies and admission control (Gatekeeper/OPA), auditing, hardening.
- OpenShift networking:
- CNI (OpenShiftSDN/OVNK), ingress/egress, routes, load balancers, service mesh (Istio/Service Mesh).
- Storage and persistence:
- Provisioning PersistentVolume/PersistentVolumeClaim, StorageClasses, CSI drivers, NAS/SAN integration (NFS, Ceph, …).
- Observability:
- Logging and metrics (Cluster Logging, Loki/EFK, Prometheus/Grafana), alerting, SIEM integration.
- CI/CD and images:
- BuildConfigs/ImageStreams, registry management (Quay/Artifactory), image policies.
- Operations and SRE:
- Cluster and application backup/restore (Velero, etcd backup).
- Capacity planning, autoscaling (HPA/VPA/Cluster Autoscaler), performance tuning.
Troubleshooting: pods, nodes, networking, storage, scheduling.
Primary Responsibilities
- Install and configure OpenShift components and RHEL and Unix OSes to host workloads.
- Deploy, maintain, and upgrade OpenShift clusters and their operators.
- Apply and test OS and platform patches; manage compliance and hardening.
- Develop and implement security and management procedures (OS and OpenShift).
- Update standard policies based on environmental changes and audit findings.
- Improve system and cluster performance; propose optimization initiatives.
- Identify, diagnose, and resolve system and platform incidents (L2/L3).
- Plan, coordinate, and execute installation, testing, and maintenance of system software and OpenShift components.
- Lead projects within approved timelines, including migrations to OpenShift and workload rationalization.
- Analyze software and hardware environments to detect defects and risks; propose remediations.
- Maintain up-to-date documentation: architecture, operator procedures, component inventory, runbooks.
- Implement backup and recovery strategies (OS, etcd, applications) and validate their effectiveness.
- Implement and test disaster recovery and business continuity (DR/BCP) procedures for OS and OpenShift.
Perform performance maintenance routines to ensure continuous availability.
