Job Description:

The Senior Data Center Operations Engineer is responsible for the bedrock of our high-availability infrastructure. This role bridges the gap between physical hardware and the Red Hat OpenShift Container Platform (OCP). Your mission is to ensure 99.99% availability by architecting resilient physical layouts and automating the deployment, scaling, and self-healing capabilities of our production clusters.

Job Responsibility:

  • Design and development of a scalable distributed management plane infrastructure to manage Palo Alto Networks’ next-generation network security solutions
  • Ensure 99.99% availability by architecting resilient physical layouts and automating the deployment, scaling, and self-healing capabilities of our production clusters
  • Monitor and maintain data center systems with a focus on 'Zero Single Point of Failure' (ZSPoF) architecture for OpenShift control planes and worker nodes
  • Implement and manage OpenShift 4.x clusters across multiple power and cooling zones to ensure 99.99% uptime
  • Design, test, and execute automated failover strategies and backup/restore procedures using tools like OADP (Velero) and Red Hat ACM
  • Perform routine maintenance and upgrades using GitOps (ArgoCD) and the Machine Config Operator to ensure zero-downtime node evacuations and patching
  • Resolve deep-stack hardware and software issues, from faulty GPU firmware to OpenShift SDN (OVN-Kubernetes) network latencies
  • Coordinate with vendors for specialized hardware (e.g., NVIDIA, Dell, Cisco) while maintaining strict security and firmware compliance
  • Optimize rack density for high-performance GPU clusters while managing thermal loads and power distribution (PDU) to prevent circuit-trip outages
  • Maintain accurate documentation and integrate hardware health metrics (IPMI/SNMP) into Prometheus/Grafana for proactive alerting
  • Rack and stack high-density GPU servers, ensuring redundant power-pathing and high-speed (100G/200G) InfiniBand or Ethernet cabling
  • Perform precision physical installation and replacement of critical components (CPUs, GPUs, NVMe storage) in a live production environment without impacting cluster quorum

Requirements:

  • Bachelor's degree in Computer Science, IT, or equivalent experience
  • 5+ years of experience specifically operating Red Hat OpenShift (OCP) in a production environment
  • Deep experience racking/stacking and cabling high-density GPU systems (e.g., NVIDIA DGX or similar) and specialized AI/ML hardware
  • Advanced proficiency in Ansible or Pulumi for automating bare-metal provisioning and cluster configuration
  • Strong Python and Bash skills for developing custom health-check scripts and API integrations
  • Expert-level CoreOS and RHEL administration, including kernel tuning and systemd management
  • Solid understanding of BGP, VLAN tagging, LACP, and Load Balancing (F5/NGINX) essential for cluster ingress
  • Experience with vSphere or KVM, and persistent storage solutions like OpenShift Data Foundation (ODF) or Ceph
  • Familiarity with DCIM tools (Netbox) and monitoring stacks ( ELK/Lok ..etci)
  • Ability to lift and move equipment up to 50 pounds (e.g., high-density 2U/4U servers)
  • Comfortable working in high-decibel, climate-controlled data center aisles
  • Capable of standing, walking, and performing precision cabling in tight rack spaces for extended periods
  • May require occasional travel to remote data center sites or edge locations
