Role Purpose:
We are seeking a seasoned infrastructure professional to fully own, design, optimize, and stabilize our server, virtualization, Linux, and datacenter rack environments. This is not a general IT administrator role .

The role exists to address performance issues, inefficient designs, and gaps in expertise in our current server and VM workplace—particularly in Linux systems and datacenter rack architecture. The successful candidate will drive deep root-cause analysis, architectural redesign, and performance optimization, going beyond day-to-day operations.

Key Responsibilities:

1. Server & Virtualization Ownership
- Full ownership of Windows Server (2016 / 2019 / 2022) and Linux Servers (RHEL, Rocky Linux, Ubuntu, Debian).
- Design, build, optimize, and maintain Hyper-V environments.
- Advanced VM lifecycle management including:
- VM sizing and placement
- Resource optimization
- Template creation and standardization

2. Deep Linux Expertise (Mandatory)
- Advanced Linux administration: systemd, kernel tuning, ulimits.
- Performance tuning for CPU, memory, disk,



and network.
- Filesystem and storage management (ext4, XFS, LVM design/optimization).
- Linux networking: iptables/nftables, VLANs, bonding, MTU optimization.
- Advanced CLI troubleshooting: top, htop, iotop, vmstat, perf, strace, lsof.
- Shell scripting (Bash, Python) for automation and diagnostics.
- Troubleshoot Linux systems without GUI tools .

3. Datacenter Architecture & Design (Optional)
- Troubleshoot hardware performance issues.
- Understand CPU and memory architectures (Intel/AMD, NUMA, DIMM rules).
- Knowledge of RAID controllers vs HBAs, NVMe/SAS/SATA characteristics.
- Datacenter expertise: rack layout, power/cooling, hardware lifecycle planning.

4. Performance Optimization & Root-Cause Analysis
- Diagnose complex performance issues across hardware, hypervisor, OS, and application layers.
- Analyze metrics from hardware counters, hypervisor data, and OS statistics.
- Lead perfo
