Validate system performance and data integrity, conduct tuning and optimization, and ensure high availability, reliability, and disaster recovery capabilities.
Produce clear documentation for runbooks, standard operating procedures, and migration activities; share learnings and support problem resolution across teams.
Apply agile methodologies to manage timelines and deliverables, and ensure compliance with security, change management, and operational standards.

Advanced expertise in building, operating, tuning, and troubleshooting Linux and Windows Server environments for high availability and performance.
In‑depth knowledge of enterprise storage systems (e.g., NetApp, Dell EMC) and advanced storage architectures (NAS, SAN), including volume/LUN management, host mapping, multipathing, data replication, and snapshots.
Strong proficiency in scripting languages (Python, Bash, PowerShell) for infrastructure automation.
Experience developing and maintaining infrastructure‑as‑code solutions using configuration management tools (Ansible, Terraform, etc.).
Hands‑on experience in data centre operations, including hardware installation, rack management, cabling, power management, and environmental monitoring.
Solid understanding of Cisco‑based network architectures and fundamental networking concepts as they relate to compute/storage connectivity.
Experience with capacity planning, performance tuning, and optimization of compute and storage resources.
Familiarity with monitoring and logging tools for infrastructure performance (e.g., Grafana, Prometheus, ELK stack).
Knowledge of disaster recovery and business continuity planning for compute and storage systems.
