Job Description

We are seeking a highly skilled and experienced Senior DevOps Engineer to join our team and take a critical role in managing and evolving our cloud-native infrastructure. The ideal candidate will have over 5 years of experience in DevOps practices with a strong background in automating, scaling, and securing modern cloud environments—specifically in Google Cloud Platform (GCP).

As part of our DevOps team, you will work closely with software engineering and infrastructure teams to deliver reliable, scalable, and efficient systems. You’ll be expected to demonstrate expertise with Terraform, Docker, Kubernetes, Helm, and Argo CD to streamline infrastructure provisioning, container orchestration, and continuous delivery processes.

Key Responsibilities

Design, build, and maintain infrastructure on GCP using Terraform (IaC).
Implement and manage containerization using Docker.
Deploy, scale, and manage applications using Kubernetes.
Use Helm to package and deploy Kubernetes applications in a consistent, repeatable way.
Set up and maintain CI/CD pipelines using Argo CD to support automated deployment strategies.
Monitor infrastructure and applications, ensuring availability, performance, and cost-efficiency.
Collaborate with engineering teams to implement DevOps best practices across the development lifecycle.
Conduct system troubleshooting and problem-solving across platform and application domains.
Improve and maintain observability with logging, metrics, and alerting tools.
Ensure security and compliance best practices are followed throughout the DevOps processes.
Provide training and upskilling to internal IT teams to ensure knowledge transfer and long-term maintainability of systems.

Requirements

5+ years of hands-on DevOps experience in a production environment.
Proven experience working with Terraform to provision and manage cloud infrastructure.
Deep understanding of Docker containers and container lifecycle.
Production-level experience deploying and managing workloads in Kubernetes clusters.
Strong knowledge of Helm for templating and managing Kubernetes deployments.
Hands-on experience with Argo CD or similar GitOps-based CI/CD tools.
Proficiency with Linux systems, shell scripting, and infrastructure monitoring.
Experience working in GCP or another major cloud provider (AWS/Azure) with a focus on automation and scalability.
Familiarity with Git, GitOps workflows, and source control branching strategies.
Solid understanding of networking, security, and cloud cost management.

Preferred Qualifications

GCP certification(s) (e.g., Associate Cloud Engineer, Professional DevOps Engineer).
Experience with service meshes (e.g., Istio, Linkerd).
Exposure to secret management tools like HashiCorp Vault, Sealed Secrets, or GCP Secret Manager.
Familiarity with observability tools (e.g., Prometheus, Grafana, Stackdriver).
Knowledge of other CI/CD systems such as Jenkins, GitHub Actions, or GitLab CI is a plus.

Zero to Hero in DevOps: The Ultimate Guide for Beginners

https://www.nilebits.com/blog/2025/05/zero-to-hero-in-devops/

Are you curious about DevOps, overwhelmed by all the tools, or simply don’t know where to begin? This guide is crafted for absolute beginners—those who are new to tech or just getting started in software development, operations, or system administration.

By the end of this guide, you’ll have a crystal-clear path to mastering DevOps and becoming job-ready—even if you're starting with zero experience.

What is DevOps?

DevOps is a combination of Development and Operations. It's not just a tool or a job title—it's a culture that promotes collaboration between developers and IT operations teams, focusing on automation, efficiency, and continuous delivery.

Key Benefits of DevOps

Faster software releases
Improved collaboration
Greater automation and fewer errors
Scalable and reliable infrastructure

DevOps Lifecycle Overview

Understanding the DevOps lifecycle is the first step toward becoming a pro:

Plan – Define features, requirements, and timelines.
Develop – Code the application.
Build – Compile and package the application.
Test – Automatically test the code for bugs.
Release – Make the app available to users.
Deploy – Push the app to servers or containers.
Operate – Maintain app availability and performance.
Monitor – Track logs, metrics, and user behavior.

Step-by-Step DevOps Learning Roadmap

Here’s how you go from zero to hero, broken down by stages.

Stage 1: Learn the Basics (Weeks 1–4)

Linux and Terminal

Commands: ls, cd, cat, grep, chmod
Scripting: Bash basics

Resources:

Git and Version Control

Core commands: git clone, commit, push, branch, merge
GitHub for hosting

Resources:

Git Handbook by GitHub

Stage 2: Automate Everything (Weeks 5–8)

Continuous Integration / Continuous Deployment (CI/CD)

Learn tools like Jenkins, GitHub Actions, or GitLab CI/CD
Build pipelines to automate code testing and deployments

Jenkinsfile Example:

pipeline {
  agent any
  stages {
    stage('Build') {
      steps { echo 'Building...' }
    }
    stage('Test') {
      steps { echo 'Testing...' }
    }
    stage('Deploy') {
      steps { echo 'Deploying...' }
    }
  }
}

Stage 3: Learn Infrastructure as Code (Weeks 9–12)

Terraform

Define and provision infrastructure using code

Example:

provider "aws" {
  region = "us-east-1"
}

resource "aws_instance" "web" {
  ami           = "ami-0c55b159cbfafe1f0"
  instance_type = "t2.micro"
}

Stage 4: Master Containers and Orchestration (Weeks 13–16)

Docker

Create lightweight, portable application containers

Dockerfile Example:

FROM node:18
WORKDIR /app
COPY . .
RUN npm install
CMD ["node", "index.js"]

Kubernetes

Manage containers at scale with orchestration

Read: Kubernetes as a Database? What You Need to Know

Stage 5: Monitoring and Logging (Weeks 17–20)

Tools:

Prometheus + Grafana – For metrics
ELK Stack – For centralized logging
