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.
The role will support large-scale enterprise environments and ensure high availability, scalability, and performance optimization across all infrastructure layers.
Key Responsibilities
1. Infrastructure Architecture & Design Define and maintain end-to-end infrastructure architecture across:
Compute (IBM AIX, Linux, Windows)
Virtualization (VMware – ESXi, vCenter)
Storage (SAN/NAS, backup platforms)
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.
2. 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, DB, and infra teams for growth planning.
3. Performance Engineering & Optimization Lead performance analysis and tuning across AIX/Linux/Windows and VMware environments
Identify bottlenecks across: CPU, memory, disk IO, network throughput
Optimize workloads using tools/technologies (e.g., monitoring, alerting platforms as referenced in infra monitoring scope)
Drive proactive performance improvement initiatives
4. Compute Platform Leadership (AIX / Windows / VMware)
Oversee: AIX (POWER, LPAR, PowerVC environments)
Windows Server & Active DirectoryVMware infrastructure lifecycle (ESXi, vCenter, clusters)
Support activities including: OS monitoring, patching, lifecycle managementVM provisioning, decommissioning, and performance tuning.
5. 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 tools like enterprise backup (e.g., Spectrum Protect, etc. based on environment patterns) 6. Network Architecture & Integration Define and review:
Data center networking, routing/switching
Connectivity between compute, storage, and application layers
Work closely with network architects for performance troubleshooting
Ensure network supports infrastructure scalability and HA needs
7. Monitoring, Automation & Reliability Implement and enhance monitoring solutions for infra health, alerts & performance
Drive automation for:
Provisioning Capacity reporting
Performance tuning
Improve observability across infra stack
8. 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)9. Disaster Recovery & High Availability Design DR/HA solutions for critical infrastructure
Ensure infrastructure readiness for failover scenarios
Periodically validate DR drills
Required Skills & Experience Core Technical Skills Compute IBM AIX (LPAR, Power systems, PowerVC)
Linux (RHEL)
