DevOps Engineer (Linux & Infrastructure Focus)

We are looking for a hands-on DevOps Engineer who can design, build, troubleshoot, and secure production systems. This role requires strong expertise in Linux, networking, and real-world infrastructure management. This is not a pipeline-only DevOps role.

Key Responsibilities:

Infrastructure & Systems:

• Design and deploy cloud infrastructure (AWS, GCP, Azure, or DigitalOcean)
• Configure and manage Linux servers in production environments
• Set up and optimize Nginx/Apache for high-performance workloads
• Implement reverse proxy, SSL, DNS, and load balancing
• Ensure high availability, scalability, and disaster recovery

Production Operations:

• Debug real-time production issues (CPU, memory, network, latency)
• Perform root cause analysis and implement preventive measures
• Monitor system performance using logs, metrics, and alerts
• Optimize system performance (kernel tuning, file descriptors, process limits)

DevOps (Practical Implementation):

• Build and maintain CI/CD pipelines (GitHub Actions, GitLab CI)
• Manage Docker-based deployments and container environments
• Automate infrastructure using Terraform / Ansible

Security & Hardening:

• Identify and fix system and application vulnerabilities
• Implement firewall rules, WAF, Fail2Ban, and intrusion detection
• Conduct security audits and vulnerability assessments
• Monitor and respond to security incidents

Required Skills:

• Strong Linux command-line expertise (top, htop, netstat, ss, lsof, tcpdump)
• Experience configuring Nginx/Apache from scratch
• Good understanding of DNS, SSL/TLS, HTTP/HTTPS, reverse proxy
• Strong networking fundamentals (TCP/IP, ports, firewalls)
• Hands-on experience with Docker and containerization
• Experience with at least one cloud platform
• Ability to debug production issues independently
• Knowledge of server hardening and security best practices

Preferred Skills:

• Understanding of OWASP Top 10 vulnerabilities
• Experience with WAF/CDN (e.g., Cloudflare)
• Familiarity with monitoring tools like Prometheus and Grafana
• Experience securing Node.js, Python, or web applications
• Knowledge of database performance and security

Mandatory Practical Experience (At least 2 required):

• Set up a production server from scratch
• Configured Nginx as a reverse proxy with SSL
• Handled and resolved a real production outage
• Implemented firewall rules or Fail2Ban manually
• Tuned systems for performance under load

Who Should Apply:

• Engineers with strong Linux debugging and system-level expertise
• Candidates who understand infrastructure internals beyond tools
• Professionals experienced in handling real production environments

Who Should Not Apply:

• Candidates focused only on CI/CD pipelines
• Engineers relying completely on managed cloud services
• Candidates without hands-on Linux troubleshooting experience
