Software Developer – AWS (Application Modernization & Cloud Migration)

Overview

CTIS is seeking an experienced Software Developer with AWS expertise to support an application modernization and cloud migration initiative. This role focuses on transforming monolithic Java/J2EE applications currently hosted on on-premises infrastructure into scalable, secure, and cost-effective cloud-native solutions on Amazon Web Services (AWS).

The ideal candidate will have strong hands-on experience with Java/J2EE application architectures and AWS cloud services, along with a proven track record of supporting large-scale migration and modernization efforts. You will play a critical role in designing, implementing, and optimizing cloud-native solutions using microservices, containers, and serverless technologies while ensuring performance, security, and operational excellence.

This is a hybrid role with 3 days in-person required in the office. 

Responsibilities

• Support the assessment of existing Java/J2EE applications (Struts, Spring, Hibernate, WebLogic) to identify opportunities for cloud-native transformation on AWS.
• Design, develop, and implement solutions to migrate and modernize monolithic Java/J2EE applications into microservices-based, cloud-native architectures in alignment with defined migration strategies.
• Develop and enhance containerization approaches for Java applications using Docker and deploy workloads on AWS ECS and/or EKS.
• Implement serverless solutions leveraging AWS Lambda, API Gateway, SQS, SNS, and other AWS-native services.
• Collaborate closely with cross-functional teams to refactor and optimize legacy Java codebases for cloud environments, promoting twelve-factor application principles and best practices.
• Support and maintain CI/CD pipelines (e.g., Atlassian Bamboo, Bitbucket, AWS CodePipeline, Jenkins, GitLab CI) to enable automated builds, testing, and deployments.
• Implement cloud security, reliability, and scalability best practices, including IAM, network security, monitoring (CloudWatch, X-Ray), and centralized logging.
• Monitor and optimize AWS resource utilization and cost efficiency in alignment with project and organizational goals.
• Stay current with AWS services, cloud migration patterns, and industry best practices, contributing to continuous improvement efforts across CTIS programs.
• Develop and maintain technical documentation, including architecture diagrams, migration artifacts, and operational runbooks.
• Troubleshoot and resolve complex issues related to cloud-native applications, integrations, and supporting infrastructure.
• Utilize Infrastructure as Code (IaC) tools such as AWS CloudFormation or Terraform to automate and standardize infrastructure provisioning across environments.

Qualifications

• Bachelor’s degree in Computer Science, Engineering, or a related discipline (or equivalent practical experience).
• 1–2 years of hands-on experience migrating applications to the AWS platform, with a minimum of 5 years of overall software development experience.
• Demonstrated experience migrating applications from on-premises environments to AWS using established migration tools and methodologies.
• Strong Java programming skills with experience in J2EE frameworks such as Spring, Hibernate, and JSF.
• Extensive hands-on experience with AWS services including EC2, S3, RDS, VPC, Lambda, API Gateway, SQS, SNS, and DynamoDB.
• Experience with containerization technologies (Docker) and orchestration platforms such as AWS ECS and EKS.
• Familiarity with Infrastructure as Code (IaC) tools including AWS CloudFormation or Terraform.
• Experience with messaging and streaming platforms such as Apache Kafka or Amazon Kinesis.
• Solid understanding of DevOps and CI/CD best practices.
• Strong problem-solving skills and the ability to troubleshoot issues in distributed, cloud-based environments.
• AWS Certified Developer – Associate or Professional (Preferred).

This is a contract role with an hourly rate of $65 - $75 DOE.
