We are seeking Monitoring Linux System Engineers (L1/L2) to join our Reliability Monitoring team. We welcome applicants at both levels — L1 for those building their foundation in Linux monitoring and support (watch monitoring dashboards, perform first-level triage, run documented checks and runbooks, and escalate complex incidents with clear context), and L2 for those ready to own deeper troubleshooting and escalations (deeper diagnosis of kernel, performance, and security issues, acting as the escalation point for L1, tuning monitoring thresholds, and driving incidents to resolution with minimal supervision — suited to candidates with 2+ years of hands-on Linux hosting experience).

This is a hybrid role (not permanent work-from-home) operating in a 24x7 rotational shift setting. Shifts rotate approximately every two weeks, and weekly days off are rotational. Flexibility to cover night and weekend shifts on a rotational basis is required; specific shift allocation will be confirmed during onboarding.

Key Responsibilities

Administer and maintain Linux-based web hosting infrastructure (CentOS, Ubuntu), including command-line operations, user management, file permissions, and service control

Configure and troubleshoot web servers (Apache, Nginx), virtual hosts, and performance tuning

Diagnose kernel-level issues such as high load, memory pressure, kernel panics, hung processes, and performance bottlenecks using system and kernel-level logs

Monitor infrastructure and respond to alerts around the clock — assess impact, perform initial mitigation, and escalate appropriately with clear documentation

Review suspicious or abusive connections, identify malicious IPs, and block them via firewall rules or tools like Fail2ban

Handle malware or hacked websites — scan for infections,



clean malicious files, secure compromised accounts, and guide customers on hardening

Perform website migrations (WordPress, Magento), handle file/database transfers, and restore backups

Requirements

Strong Linux system administration skills (CentOS, Ubuntu)

Web server management (Apache, Nginx)

Infrastructure and performance troubleshooting using top, htop, iotop, vmstat, and iostat

Monitoring and alerting experience with tools such as Prometheus, Nagios, Zabbix, or Datadog, including alert threshold tuning and noise reduction

Networking fundamentals (TCP/IP, ports, firewalls, routing, latency, packet loss)

Bash scripting for automation of checks, log analysis, and repetitive operational tasks

Preferred Qualifications

DNS management — record creation (A, CNAME, MX, TXT), propagation checks, and resolution troubleshooting

Email systems — configuring and diagnosing Postfix/Exim, SMTP troubleshooting, and understanding SPF, DKIM, and DMARC

Database management — MySQL backups, restores, user privileges, and basic query troubleshooting

Control panel familiarity with cPanel/WHM, Plesk, or similar hosting platforms

Disk management — checking disk space (df, du), identifying large files, handling inode exhaustion, RAID, and managing partitions or LVM

Security fundamentals — firewall configuration (iptables, firewalld), malware scanning (ClamAV, Maldet), and SSH hardening

Excellent communication skills, with the ability to explain technical issues to non-technical clients and document solutions clearly

Bonus: configuration management tools (Ansible, Puppet), Docker, Python scripting, high-traffic WordPress/Magento environments, PHP-FPM tuning, CDN and caching layers (Cloudflare, Varnish, Redis), prior NOC or 24x7 reliability monitoring experience
