Own network architecture operational stability including routing, switching, WAN/LAN optimization, VLANs, VPNs, load balancing and network redundancy; supervise network health monitoring and firmware lifecycle.
Manage storage and backup infrastructure (SAN, NAS, object storage), establish backup and retention policies, validate restore procedures, and drive continuous improvement of RPO/RTO objectives.
Lead cloud transition, hybrid-cloud integration and ongoing management of cloud resources (AWS, Azure, GCP): cost control, architecture governance, secure connectivity, and cloud-native operations patterns.
Implement and enforce infrastructure security controls in partnership with InfoSec: host and network hardening, vulnerability scanning, patch cadence, endpoint protection, segmentation, and IAM best practices.
Develop and maintain disaster recovery (DR) and business continuity plans, runbook authoring, DR testing, failover/recovery exercises and periodic validation of recovery time and recovery point objectives.
Create and maintain comprehensive operational documentation, runbooks, run-deck procedures, system diagrams and configuration baselines to accelerate troubleshooting and reduce single-person dependencies.
Drive automation and tooling adoption (Ansible, Terraform, PowerShell, Bash, Python) to reduce manual provisioning, improve consistency, and increase deployment velocity while minimizing configuration drift.
Execute capacity planning and performance forecasting for CPU, memory, network, storage and cloud spend, presenting actionable recommendations and budget impacts to senior stakeholders.
Lead vendor relationships and supplier performance management for hardware, networking, cloud providers and managed services; negotiate contracts, SLAs, support escalations and warranty management.
Own infrastructure change advisory board (CAB) coordination for major infrastructure changes, impact analysis, rollback planning and stakeholder communications to minimize business disruption.
Establish and report on key infrastructure KPIs and SLAs (uptime, mean time to resolution, patch compliance, backup success rates, capacity utilization) to leadership and business units.
Oversee hardware procurement, inventory tracking, asset tagging and lifecycle refresh plans to ensure cost-effective equipment replacement and sustainability compliance.
Collaborate with application teams, DevOps and security to onboard new applications, define capacity/security requirements, and influence architecture decisions for performance, availability and compliance.
Lead cost optimization initiatives across on-prem and cloud environments including rightsizing, reserved instances, storage tiering and consolidation strategies to realize measurable savings.
Drive continuous improvement initiatives using post-incident reviews, process audits and automation roadmaps to reduce operational toil and improve system reliability over time.
Ensure compliance with regulatory and audit requirements (PCI, HIPAA, SOC 2, GDPR) related to infrastructure, participating in control implementation, evidence collection and remediation tracking.
Coordinate remote site infrastructure and connectivity for branch offices, retail locations or industrial environments, including WAN optimization, remote monitoring and on-site vendor coordination.
Support major IT projects and migrations (data center consolidation, cloud migration, network refresh) by defining technical deliverables, resource plans, risk mitigation and testing strategies.
Implement monitoring, observability and alerting strategy across infrastructure stack (Prometheus, Nagios, Datadog, Splunk) and define escalation processes to reduce alert fatigue and improve MTTR.
Champion operational excellence through onboarding programs, team training, documentation standards and knowledge-sharing sessions to build a resilient, multi-skilled infrastructure team.

Secondary Functions

Participate in cross-functional strategic planning to align infrastructure roadmap with product and business objectives.
Assist with budget planning and forecasting for infrastructure capital and operational expenditures, providing inputs on project cost-benefit and lifecycle implications.
Support procurement, vendor evaluation, RFP/RFI processes and contract review to secure competitive pricing and service-level assurances.
Provide subject-matter expertise for security assessments, internal audits and external compliance reviews, preparing required documentation and remediation plans.
Serve as an escalation point for complex incidents, major outages and cross-team coordination during critical incident response.
