• Security & Compliance: Implement rigorous security controls, including Role‑Based Access Control (RBAC), network policies, and container image scanning.
• Performance Tuning: Monitor cluster health, troubleshoot complex infrastructure issues, and optimize resource utilization using Prometheus and Grafana.
• Backup & Recovery: Design and test robust disaster recovery (DR) and backup strategies for stateful and stateless containerized workloads.
• Local Collaboration: Work directly with on‑site application development teams to guide them on cloud‑native best practices and microservices architecture.

Required Skills and Qualifications

• Experience: Minimum of 5 years of hands‑on experience in container orchestration, specifically dedicated to Red Hat OpenShift (OCP) and Kubernetes.
• Operating Systems: Deep expertise in Red Hat Enterprise Linux (RHEL) and RHEL CoreOS (RHCOS).
• Infrastructure as Code: Proficiency with automation tools like Ansible, Terraform, or Puppet.
• Networking & Storage: Strong understanding of OpenShift networking (OVN‑Kubernetes) and enterprise storage solutions (CSI, Ceph, ODF).
• Programming/Scripting: Competency in scripting languages such as Bash, Python, or Go for infrastructure automation.
• Location Requirements: Must be willing to work fully on‑site in Singapore and meet local employment authorization criteria.
• Preferred Banking Experience: Experience maintaining compliance with international and local financial standards (e.g., PCI‑DSS, SOC2). Experience deploying highly secure, isolated network zones (DMZ) for internet‑banking applications. Proven track record of managing high‑transaction, low‑latency microservices architectures.
• Certifications: Red Hat Certified Specialist in OpenShift Administration or Red Hat Certified Architect (RHCA) is preferred.
