What to Include on a Infrastructure Engineer Resume

• A concise summary that states your infrastructure engineer experience level, strongest domain, and the business problems you solve.
• A skills section that mirrors the job description language for Linux/Windows Server, VMware/Hyper-V, Networking (TCP/IP, DNS, VPN), Ansible.
• Experience bullets that connect infrastructure engineer, systems engineer, network infrastructure to measurable outcomes such as cost savings, faster delivery, better quality, or improved customer results.
• Tools, platforms, certifications, and methods that are current for devops & cloud roles.

Sample Experience Bullets

• Managed hybrid infrastructure across 3 data centers and AWS with 500+ VMs and 2,000+ containers running at 99.97% uptime, handling routine maintenance windows, emergency patching, and capacity expansions. The environment supports 5,000+ internal users and customer-facing applications
• Wrote Ansible playbooks for automated server provisioning covering OS configuration, security hardening, monitoring agent installation, and application deployment, cutting provisioning time from 4 hours to 15 minutes across 300+ servers. The playbooks are version-controlled and tested in a staging environment before production use
• Designed the network segmentation strategy that separates production, staging, and corporate traffic into isolated VLANs with strict firewall rules between zones. The architecture passed PCI DSS compliance audits for 3 consecutive years without findings
• Led a data center consolidation project that migrated 200+ workloads from 2 aging facilities to a single modern data center and AWS, reducing the physical footprint by 60% and saving $800K annually in hosting, power, and cooling costs
• Built capacity planning scripts that analyze historical resource utilization data and project future needs based on growth trends, predicting and preventing 12 potential capacity-related outages over 18 months. The scripts run weekly and generate reports for the infrastructure team
• Maintained a monthly patching cycle for Linux and Windows servers with automated patch testing in staging before production rollout, achieving zero security incidents from unpatched vulnerabilities. The patching process covers 300+ servers and completes within a single maintenance window
• Managed storage infrastructure including SAN and NAS systems totaling about 200TB, monitoring capacity utilization, configuring LUN allocations, and planning expansions before teams hit storage limits. Annual storage growth is about 15% and all expansion requests have been fulfilled proactively
• Worked with the networking team on firewall rule changes, VPN tunnel configurations, and load balancer updates for new service deployments, processing about 20 change requests per week with documented approval workflows. Average change implementation time was under 4 hours
• Served as on-call for infrastructure issues on a weekly rotation, maintaining a 15-minute response time SLA and documenting all incidents in ServiceNow with root cause analysis and remediation steps. Incident response procedures are reviewed and updated quarterly
• Implemented centralized log collection using rsyslog and Elasticsearch for all server infrastructure, giving the security team full audit trails and the operations team the ability to search across all hosts from a single Kibana dashboard. Log retention covers 90 days per compliance requirements
• Set up automated monitoring with Zabbix for all physical and virtual infrastructure including CPU, memory, disk, and network metrics with escalating alert thresholds. The monitoring system catches hardware failures before they cause service impact about 80% of the time
