JobType: full-time

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.

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
- Solid 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.)

Positive 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)

What Success Looks Like

- Reliable and predictable system deployments with seamless rollback capability
- Clear system visibility through actionable metrics and logs
- Fast, accurate root-cause diagnosis at the OS, network, and application layers
