DevOps Engineer (Linux & Infrastructure Focus)

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

Job Type: Permanent
