• Work with external security vendors or auditors on penetration tests, security assessments, and remediation plans

Backup, Disaster Recovery & Business Continuity

• Develop, manage, and test backup, restore, and disaster recovery strategies (offsite backups, replication)
• Establish and validate recovery time objectives (RTO) and recovery point objectives (RPO)
• Plan and execute infrastructure failover and disaster recovery exercises
• Ensure ongoing data integrity, redundancy, and availability

Leadership & Collaboration

• Lead and mentor infrastructure / operations staff and contractors
• Collaborate with software and business systems teams to ensure infrastructure meets their needs (even though you don???t own those systems)
• Serve as the escalation point for infrastructure outages, performance issues, or security incidents
• Maintain vendor relationships (hardware vendors, network providers, security tool vendors)
• Define budgets, forecasts, and capital expenditures for infrastructure-related investments
• Produce regular reports on infrastructure health, security posture, capacity, and performance

Documentation & Standards

• Maintain up-to-date documentation (network diagrams, infrastructure inventories, configurations, troubleshooting guides)
• Define and enforce infrastructure change control, patch, and maintenance windows

• Prior experience operating in regulated industries or compliance frameworks
• Experience with hybrid or multi-cloud setups
• Experience with monitoring, alerting, logging (e.g. Nagios, Zabbix, Prometheus, ELK, Splunk)

Key Performance Indicators (KPIs) / Metrics

• Infrastructure uptime / availability (percentage)
• Mean time to restore (MTTR) for outages
• Number / severity of security incidents tied to infrastructure
• Patch compliance / vulnerability remediation metrics
• Capacity utilization vs headroom
• Number of successful DR test recoveries
• Infrastructure costs vs budget

Working Conditions

• May require occasional off-hours or weekend support for planned maintenance or emergency issues
• May require physical presence in data centers or server rooms
• On-call rotation for critical infrastructure support
