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
- Positive 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
