Job Title: DevOps Engineer (Linux & Infrastructure Focus)
Location: Coimbatore
Job Type: Full-Time
Job Overview:
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 Digital Ocean)
● 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
