DevOps Engineer: Career Guide

What Does a DevOps Engineer Do?

DevOps engineers build and maintain the systems that let a team ship code reliably — CI/CD pipelines, cloud infrastructure, monitoring, and incident response. The role sits between development and operations: you're writing automation code, but the goal is always a more reliable, faster-shipping system rather than a new product feature.

Day to day ranges from writing a deployment script or Terraform config to getting paged at 2 a.m. when a service goes down — the on-call side of the role is real and worth knowing about before you commit to this track.

Skills & Qualifications

A working knowledge of Linux, one scripting language (Python or Bash), containers (Docker), and at least one cloud provider (AWS, Azure, or GCP) covers the core of most job postings. Infrastructure-as-code tools like Terraform and orchestration with Kubernetes are increasingly expected beyond entry level. Cloud provider certifications (AWS Solutions Architect Associate, for example) are a strong signal for freshers without prior ops experience.

Typical Starting Salary in India

Entry-level DevOps salaries in India generally fall between ₹4-5.5 LPA, with freshers who bring specialized skills in cloud, Kubernetes, Docker, or Python able to command ₹6-8 LPA. Pay varies by city too: Bengaluru runs highest at roughly ₹5.5-8 LPA given the concentration of IT employers there, Hyderabad around ₹5-7.5 LPA, Pune ₹4.5-7 LPA, and Tier-2 cities ₹3.5-5 LPA. Product-based companies generally pay more than services companies at this level, since DevOps engineers there manage production infrastructure directly rather than client-delivery pipelines.

Typical Career Path

Most engineers enter through a Software Engineer or Systems Administrator role and move into DevOps after 1-2 years of exposure to deployment and infrastructure work. From there: DevOps Engineer → Senior DevOps/SRE → Platform Engineering Lead or Infrastructure Architect.

Common Interview Questions to Expect

Expect a Linux troubleshooting scenario ("a service is using 100% CPU — how do you find out why?"), a walkthrough of a CI/CD pipeline you've built or used, and a conceptual question distinguishing containers from virtual machines. Basic Kubernetes questions (what a pod is, why you'd use a deployment vs. a bare pod) and a simple cloud scenario — such as securing an S3 bucket or setting up an IAM role with least-privilege access — are common at product companies. A short scripting question (parse a log file and count errors by type, for example) tests hands-on ability directly.

How to Break In

Set up a personal CI/CD pipeline for one of your own projects end to end and be ready to walk through it in an interview. A concrete version worth building: a GitHub Actions workflow that runs your test suite on every push, builds a Docker image, and deploys it to a free-tier cloud service (Render, Fly.io, or a free-tier AWS/GCP instance) — this single project demonstrates version control, automated testing, containerization, and cloud deployment in one place, which is exactly what a fresher interview is trying to verify.

Direct-entry DevOps fresher roles are less common than lateral moves, so a Software Engineer or SysAdmin off-campus role is often the realistic first step.
