The Linux Administrator will be responsible for operating, maintaining, and optimizing on-premise Linux infrastructure that supports large-scale, distributed systems. This role requires deep expertise in Linux internals, release engineering, and system reliability, with hands-on ownership of deployments, troubleshooting, and performance in high-load, network-intensive environments.

Unlike cloud-centric roles, this position demands strong command-line diagnostics, kernel-level understanding, and the ability to resolve issues directly on bare-metal systems.

Requirements

Key Responsibilities

Linux Systems Administration

Operate, tune, and troubleshoot bare-metal Linux servers (CPU, memory, storage, and networking)
Perform deep OS-level diagnostics using system logs, process monitoring, and kernel tools
Identify and resolve performance bottlenecks and system stability issues

Release & Deployment Management

Own end-to-end release and deployment processes for on-prem systems
Manage versioning, staged rollouts, and rollback strategies to ensure stable production releases
Coordinate and execute controlled production deployments with minimal downtime

Container & Runtime Operations

Build, optimize, and debug Docker images
Integrate containerized applications into on-prem environments
Troubleshoot container runtime and system-level issues

Networking & Connectivity

Monitor, validate, and troubleshoot network performance including latency, packet loss, and jitter
Diagnose Wi-Fi performance issues in high-density, real-time environments
Apply strong understanding of TCP/UDP, routing, and VLANs for issue resolution

Automation & Tooling

Develop and maintain Bash and Python scripts for automation, system tooling, and log analysis
Improve operational efficiency through custom tooling and workflow automation

Monitoring & Reliability

Implement and maintain monitoring and alerting using tools such as Prometheus and Grafana
Analyze logs and metrics to perform Root Cause Analysis (RCA)
Ensure system visibility, reliability, and performance across environments

Required Skills & Experience

Expert-level experience administering Linux systems (Ubuntu Server preferred)
Strong understanding of Linux internals, processes, memory management, and networking
Hands-on experience with release engineering, deployment strategies, and rollback mechanisms
Proficiency with Docker, including image optimization and debugging
Strong scripting skills in Bash and Python
Solid networking fundamentals (TCP/IP, UDP, VLANs, routing, Wi-Fi troubleshooting)
Practical experience with monitoring, observability, and log analysis tools (ELK, Prometheus, etc.)

Good to Have

Background in Site Reliability Engineering (SRE) or Build/Release Engineering
Experience running Kubernetes in on-prem or edge environments
Operational experience with databases such as PostgreSQL, MongoDB, or Redis (availability, backups)
