  • Collaborate with development teams to refactor and optimize existing Java codebases for cloud environments, promoting best practices for twelve-factor apps. Provide technical leadership, mentorship, and guidance to junior engineers on cloud migration and modernization strategies.
  • Implement and manage CI/CD pipelines (e.g., Atlassian Bamboo, Bitbucket, AWS CodePipeline, Jenkins, GitLab CI) for automated deployment and testing of cloud-native applications.
  • Ensure the security, reliability, and scalability of cloud-native applications by implementing best practices for identity and access management (IAM), network security, monitoring (CloudWatch, X-Ray), and logging.
  • Optimize AWS resource utilization and cost, identifying opportunities for efficiency improvements.
  • Stay up to date with the latest AWS services, cloud-native patterns, and industry trends, and evangelize their adoption within the organization.
  • Document architectural designs, technical specifications, and operational procedures.
  • Troubleshoot and resolve complex technical issues related to cloud-native applications and infrastructure.
  • Utilize tools like AWS CloudFormation or Terraform to define and automate infrastructure provisioning for consistent deployment across environments.
Qualifications
  • Bachelor's degree in computer science, Engineering, or a related field (or equivalent practical experience), Masters Preferred.
  • 3 to 5 years of hands-on experience migrating applications onto the AWS platform.
  • Solid migration experience from on-premises servers to the AWS platform using migration tools. Overall software development experience of at least 10 Years.
  • Strong Java programming skills and experience with J2EE frameworks like Spring, Hibernate, and JSF.
  • Extensive experience with core AWS services such as EC2, S3, RDS, VPC, Lambda, API Gateway, SQS, SNS, DynamoDB. Hands-on experience with containerization technologies (Docker) and orchestration platforms (AWS ECS, EKS).
  • Familiarity with Infrastructure as Code (IaC) tools like CloudFormation or Terraform.

  • DevOps practices for continuous integration and deployment (CI/CD)
  • Solid understanding of software development best practices, including version control, testing, and debugging.
