Job Summary

Key Responsibilities • Own Linux infrastructure lifecycle: provisioning, configuration, patching, upgrades, and capacity planning. • Design & implement: Server provisioning (Kickstart, PXE, Foreman, HA/DR architectures (e.g., Pacemaker; multi-AZ/multi-region patterns). • Automate everything: golden images, OS baselines, config compliance (Puppet/Ansible pipelines). • Build & run : Golden Image creations with lifecycle management and push to Infrastructure. • Security hardening at OS and network layers (SELinux, firewalld/nftables/IPSec, CIS baselines). • Performance engineering: low-latency tuning, kernel parameters, NUMA, I/O optimization. • Observability: Prometheus/Grafana dashboards knowledge. • Lead incident response and postmortems with blameless RCAs and concrete action plans. • Mentor engineers; contribute to architecture standards, design reviews, and runbooks. • Partner with Security, Networking, App, and DevOps teams on cross-functional deliverables. Mandatory Qualifications • 15+ years Linux engineering in production at scale (RHEL). • Expert in systemd, boot process, LVM, XFS/ext4, iSCSI/multipath, RAID; tcpdump, iproute2. • Strong Bash and Python; comfortable with regex and writing robust automation. • Hands-on with experts role in Puppet, Ansible, Cloud Migration (Azure and AWS), Git, and CI/CD tools (GitHub Actions). • Infrastructure as Code with Puppet and Ansible. • Security: SELinux, SSH hardening, vulnerability scanning (OpenSCAP/Qualys). • Cloud: experience with AWS/Azure, VPC/networking, IAM, On-prem to cloud migrations and managed K8s desirable. • Demonstrated leadership in complex troubleshooting, incident management, and mentoring. Success Metrics (First 6–12 Months) • MTTR reduced by 30% through runbooks/automation. • Baseline OS compliance 95% within 90 days; patch SLAs consistently met. • Automation coverage ( 70% of repetitive ops codified). • Documentation (golden images, infra patterns, puppet modules, playbooks) published and adopted. • Cloud Migration on-prem to AWS/Azure
