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.
Key Responsibilities
* 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, filesystem, 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
Qualifications
* 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
