System Administrator; Linux Infrastructure & Reliability

We are seeking an experienced System Administrator to design, operate, and continuously improve a Red Hat–based Linux infrastructure supporting high-availability, high-throughput systems. This role is central to maintaining operational excellence across performance-critical environments that process large volumes of network and application traffic.

This position is ideal for a senior, hands-on Linux professional who is comfortable owning production systems end-to-end, operating modern Golang-based server stacks
, and working at the intersection of systems, networking, and security.

• Architect, administer, and optimize Red Hat Enterprise Linux–based systems (RHEL and compatible distributions) across production and non-production environments
• Design and operate high-availability system architectures
  , including redundancy, failover, and capacity planning
• Deploy, configure, and operate high-performance Golang servers (custom or framework-based) for HTTP and TCP services
  , traffic handling, and backend communication
• Tune system performance at the kernel, file system, and network stack levels to support low-latency, high-throughput workloads
• Implement and maintain system observability
  : metrics, logs, alerts, and performance baselines
• Lead incident response and post-mortem analysis
  , including root-cause identification and long-term remediation
• Design and enforce backup, recovery, and disaster-recovery strategies for critical systems
• Apply security hardening
  , patch management, and vulnerability remediation in coordination with security teams
• Automate infrastructure provisioning, configuration, and operational workflows using scripting and automation frameworks
• Own system lifecycle management:
  build standards, configuration baselines, upgrades, and decommissioning
• Collaborate closely with network, security, and platform engineering teams to ensure end-to-end system reliability and resilience
• Support infrastructure scaling initiatives and contribute to architecture decisions as the platform evolves

• 3+ years of hands-on experience administering Linux systems in production environments
• Understanding of Linux internals
  , kernel behavior, process scheduling, memory management, and I/O performance
• Hands-on experience deploying, configuring, and operating high-performance Golang servers (custom or framework-based) for HTTP/TCP services, traffic handling, and backend communication
• Strong knowledge of networking fundamentals and system-level networking (TCP/IP, DNS, routing concepts, firewall interaction)
• Proven experience with performance tuning, capacity planning, and system scalability
• Experience implementing and maintaining monitoring, alerting, and centralized logging systems
• Advanced shell scripting skills (Bash or similar) for automation and operational efficiency
• Solid understanding of backup architectures, data integrity, and disaster-recovery planning
• Strong troubleshooting skills with a structured, analytical approach to complex system issues
• Ability to operate effectively in high-availability, security-sensitive, and always-on environments
