Role Overview: The Infrastructure Architect will be responsible for designing, optimizing, and managing enterprise IT infrastructure across Compute (AIX/Linux, Windows/VMware), Storage, and Network domains, with strong focus on capacity planning, performance engineering, and operational resilience.
Infrastructure Architecture & Design
* Define and maintain end-to-end infrastructure architecture across:
o Compute (IBM AIX, Linux, Windows)
o Virtualization (VMware ESXi, vCenter)
o Storage (SAN/NAS, backup platforms)
o Network (LAN/WAN, DC networking)
* Provide architectural solutions for scalable, resilient, and secure infrastructure platforms
* Ensure alignment with enterprise standards, CMDB, and configuration management practices
Capacity Planning & Management
* Perform capacity forecasting for compute, storage, and network resources
* Analyze trends for CPU, memory, storage, IO, and network utilization
* Recommend and implement capacity optimization strategies
* Collaborate with application, database, and infrastructure teams for growth planning
Performance Engineering & Optimization
* Lead performance analysis and tuning across AIX/Linux/Windows and VMware environments
* Identify bottlenecks across CPU, memory, disk IO, and network throughput
* Optimize workloads using monitoring and alerting tools
* Drive proactive performance improvement initiatives
Compute Platform Leadership (AIX / Windows / VMware)
* Oversee AIX (POWER, LPAR, PowerVC), Windows Server & Active Directory, and VMware infrastructure lifecycle (ESXi, vCenter, clusters)
* Support activities including OS monitoring, patching, lifecycle management, VM provisioning, decommissioning, and performance tuning
Storage & Backup Architecture
* Design and manage SAN/NAS storage environments
* Optimize storage performance (IOPS, throughput, latency)
* Lead backup/recovery strategy and disaster recovery alignment
* Work with enterprise backup tools such as Spectrum Protect
Network Architecture & Integration
* Define and review data center networking, routing/switching, and connectivity between compute, storage, and application layers
* Work closely with network architects for performance troubleshooting
* Ensure network supports infrastructure scalability and high‑availability needs
Monitoring, Automation & Reliability
* Implement and enhance monitoring solutions for infra health, alerts, and performance
* Drive automation for provisioning, capacity reporting, and performance tuning
* Improve observability across the infrastructure stack
Incident, Problem & Change Management
* Lead resolution of complex L2/L3 infrastructure issues
* Drive root cause analysis for recurring performance issues
* Work within ITIL processes (Incident, Problem, Change)
Disaster Recovery & High Availability
* Design DR/HA solutions for critical infrastructure
* Ensure infrastructure readiness for failover scenarios
* Periodically validate DR drills
Core Technical Skills
* Compute: IBM AIX (LPAR, Power systems, PowerVC), Linux (RHEL), Windows Server & AD
* Virtualization: VMware vSphere, ESXi, vCenter, HA, DRS
* Storage & Backup: SAN/NAS, replication, backup solutions
* Networking: LAN/WAN, routing/switching, DC networking
* Monitoring & Tools: Infrastructure monitoring, alerting tools, performance tools
Functional Expertise
* Capacity planning & trending
* Performance analysis & tuning
* Infrastructure optimization
* ITIL process awareness (Incident, Change, Problem)
Experience
* 10‑15+ years of experience in infrastructure architecture/engineering
* Proven experience in large enterprise environments (multi‑DC, hybrid infra)
Soft Skills
* Strong stakeholder management (cross teams: storage, network, apps)
* Excellent problem‑solving & analytical skills
* Ability to lead design discussions and technical governance
