Role & responsibilities

- Define and Uphold Reliability Standards: Establish and manage Service Level Objectives (SLOs), Service Level Indicators (SLIs), and error budgets for the OpenShift platform and its core services.
- Automate Everything: Design, build, and maintain robust automation to handle the full lifecycle of OpenShift clusters, including provisioning, upgrades, patching, scaling, and disaster recovery.
- Reduce Toil: Proactively identify and eliminate manual, repetitive operational work by developing and maintaining automation scripts (Python, Go, Bash) and Ansible playbooks.
- Incident Response and Root Cause Analysis: Lead high-severity incident response and conduct deep, blameless post-mortems to identify and implement permanent solutions to prevent recurrence.
- Proactive Health Management: Develop and implement automated health checks and self-healing capabilities to ensure cluster and application resilience.
- Subject Matter Expertise: Serve as the top-tier technical authority for OpenShift Container Platform architecture, networking (OVN-Kubernetes, SDN), load balancing, cross cluster management, storage (OpenShift Data Foundation/Ceph), and security.
- Observability: Architect and manage a comprehensive observability stack (e.g., Prometheus, Grafana, ELK/Fluentd) to provide deep insights into platform and application performance.
- CI/CD and GitOps: Engineer and optimize CI/CD pipelines for both platform components and tenant applications, championing GitOps principles for declarative configuration management.
- Capacity and Performance:



Conduct advanced performance tuning, load testing, and capacity planning to ensure the platform can meet future demand.
