Role Overview
We are looking for a skilled and proactive Server Administrator / DevOps Engineer to join our growing team.

You will work hands-on with Linux and Windows environments, popular hosting control panels, and AWS cloud services.
Key Responsibilities
Traffic Analysis & Network Monitoring
- Monitor, capture, and analyze inbound and outbound traffic using tools like Wireshark, tcpdump, ntopng, or similar.
- Identify abnormal traffic patterns, DDoS attempts, bots, and unauthorized access probes.
- Generate and maintain traffic reports for capacity planning and incident review.
Security — Blocking & Threat Prevention
- Configure and maintain firewall rules (iptables, UFW, AWS Security Groups, WAF) to block malicious IPs, bots, and unwanted traffic.
- Implement fail2ban, rate limiting, and geo-blocking as required.
- Set up and manage Intrusion Detection / Prevention Systems (IDS/IPS) such as Snort or Suricata.

- Conduct regular vulnerability scans and remediate findings promptly.
Cloud & Linux/Windows Infrastructure (AWS)
- Provision, configure, and manage AWS services: EC2, S3, RDS, VPC, Route 53, CloudFront, IAM, ALB, and Auto Scaling Groups.
- Administer both Linux (Ubuntu, CentOS, Debian) and Windows Server environments.
- Design and maintain highly available, fault-tolerant architectures across cloud and on-prem.
Control Panel Administration — cPanel & Plesk
- Create and manage hosting accounts, DNS zones, email, FTP, and databases via cPanel/WHM.
- Administer Plesk for multi-tenant web hosting environments including SSL provisioning and DNS management.
- Troubleshoot hosting issues including PHP version mismatches, email deliverability, and SSL renewals.
Bare-bone VPS Setup (Hostinger, HostGator, etc.)
- Provision fresh Linux VPS instances from scratch — install and configure web servers (Nginx, Apache, Caddy), databases (MySQL, PostgreSQL), and runtimes (Node.js, PHP, Python).
- Set up SSH hardening, swap space, UFW firewall, and automated backups on bare VPS environments.
- Configure reverse proxies and SSL using Caddy or Certbot/Let's Encrypt.
Application Hosting — Multi-Stack Deployments
- Deploy and maintain projects across diverse stacks: HTML/CSS static sites, React (SPA/SSR), Node.js/Express APIs, PHP, and Laravel applications.
- Manage PM2 process management for Node.js services with cluster mode, log rotation, and startup scripts.
- Configure Docker and Docker Compose for containerized deployments where applicable.
- Handle build pipelines and CI/CD workflows (GitHub Actions, GitLab CI) for automated deployments.
Scaling & Resource Optimization
- Scale server resources (vertical and horizontal) based on traffic and performance metrics without application downtime.
- Set up AWS Auto Scaling, load balancers, and CDN configurations for high-traffic scenarios.
- Monitor CPU, RAM, disk I/O, and network utilization using tools like Netdata, Prometheus, Grafana, or CloudWatch; take corrective action proactively.
Employee Machine Setup & Endpoint Monitoring
- Set up developer and non-developer machines with required tooling, including IDEs, VPNs, and company software.
- Deploy and configure endpoint monitoring and control solutions (e.g., OpenDLP, OSSEC, ManageEngine, or equivalent) to track activity, enforce policies, and detect unauthorized actions.
- Maintain device management policies and ensure compliance across all employee endpoints.
