- Splunk proficiency: dashboard development, field extraction, SPL optimization, and alerting.
- GitHub workflow: branching strategies, pull requests, and CI/CD pipeline integration.
- Linux/Windows system administration and troubleshooting.
- Physical infrastructure: comfortable with hardware installation, cabling, and IPMI/iLO management.
- Able to travel to our datacenters for deployments, maintenance, and hardware refresh cycles — usually quarterly, and sometimes on shorter notice as needs come up.

Responsibilities
- Design and maintain IaC solutions using Terraform, Ansible, or SaltStack for configuration management and deployment standardization across 5+ datacenters.

- Lead hardware procurement, specification, and installation during refresh cycles; maintain asset inventory and power/cooling optimization.
- Build Splunk dashboards, field extractors, and alerting rules for infrastructure metrics; troubleshoot performance issues through log analysis.
- Partner with development teams on GitHub-based infrastructure repositories; implement automated testing and rollback procedures for infrastructure changes.
- Implement hardening standards and vulnerability remediation (CVE patching through patching pipelines), and uphold security best practices across all systems.
- Share in the team on-call rotation, including days, nights, weekends, and holidays.
