DevOps Engineer

Job Title: DevOps / Infrastructure Engineer

Experience: 3–5 Years

Employment Type: Full-Time

ROLE OVERVIEW: The DevOps / Infrastructure Engineer is responsible for building and maintaining the deployment infrastructure on air-gapped networks. This role requires deep expertise in offline CI/CD pipelines, containerization, system hardening, and secure network configuration. The engineer ensures that the application can be reliably built, tested, packaged, and deployed in environments with no internet connectivity.

KEY RESPONSIBILITIES

 •                     Design and implement CI/CD pipelines optimized for air-gapped (disconnected) network environments

•                     Build and maintain Docker-based containerization for all application services

•                     Set up and manage container orchestration using Kubernetes or Docker Compose in offline environments

•                     Create offline package repositories and dependency mirrors for Python (pip), Node.js (npm), and system packages

•                     Automate infrastructure provisioning using Ansible, Terraform, or shell scripting

•                     Implement system and network security hardening in compliance with deployment security policies

•                     Configure and manage PostgreSQL database deployments including backup, replication, and recovery

•                     Set up monitoring, logging, and alerting using tools suitable for air-gapped networks (Prometheus, Grafana, ELK)

•                     Manage artifact versioning, release packaging, and deployment runbooks

•                     Collaborate with developers to ensure applications are deployment-ready and environment-agnostic
