  • Collaboration: Work closely with backend and frontend engineering teams to optimize the development pipeline, troubleshoot infrastructure issues, and implement new technologies and tools.
  • Automation & Optimization: Automate operational processes and optimize cloud resource usage to improve system performance and reduce costs.
  • Documentation & Knowledge Sharing: Create and maintain comprehensive documentation of system architecture, processes, and configurations. Share best practices and mentor junior DevOps engineers.

Required Qualifications:

  • 5+ years of experience in DevOps or Cloud Engineering, with a strong focus on AWS and Kubernetes.
  • Proven expertise in managing and deploying cloud infrastructure using AWS services such as EC2, ECS, EKS, Lambda, and RDS.
  • Strong hands-on experience with Kubernetes for container orchestration, cluster management, and microservices deployment.
  • Extensive experience with Infrastructure as Code (IaC) tools such as Terraform, AWS CDK, or CloudFormation.
  • Proficiency in scripting and automation using languages like Python, Bash, or Go.
  • Experience with CI/CD tools such as Jenkins, GitLab CI, or AWS CodePipeline for automated deployment and testing. Familiarity with monitoring and logging tools such as Prometheus, Grafana, Loki, or Datadog.
  • Strong understanding of cloud security best practices and IAM management.
  • Excellent problem-solving and troubleshooting skills with the ability to resolve complex infrastructure and application issues.
  • Strong communication and collaboration skills, with experience working in cross-functional teams.

Preferred Qualifications:

  • AWS Certifications (Solutions Architect, DevOps Engineer, or SysOps) are a plus.
  • Experience with serverless technologies such as AWS Lambda and Step Functions.
  • Knowledge of other cloud platforms like Azure or GCP.
  • Familiarity with additional DevOps tools like Ansible, Chef, or Puppet for configuration management.
