Role: Engineer
Required Skills: Java
Experience: 6 - 8 Years
Function: TECHNOLOGY
Apply By: 2026-11-22
Must Have Technical/Functional Skills
- 6+ years of hands-on full stack development experience; strong proficiency in Java with Spring Boot for backend microservices development - this is the primary backend stack for the migration program
- Solid frontend development skills in React.js or Angular - ability to build responsive, accessible web UIs that replace legacy mainframe screens and green-screen interfaces end users currently interact with
- Strong REST API design and development skills - ability to design clean, versioned, well-documented APIs that serve as the interface between the new cloud platform and frontend applications
- Hands-on experience with AWS cloud services used in migration programs - EC2, Lambda, API Gateway, RDS/Aurora, DynamoDB, S3, SQS, SNS, Cognito - and understanding of when to use each
- Proficiency in SQL for relational databases; experience working with both relational (RDS/Aurora, PostgreSQL) and NoSQL (DynamoDB) databases in cloud-native application design
- Experience with microservices architecture patterns - service decomposition, event-driven design, API-first development, and 12-factor application principles for cloud-native workloads
- Familiarity with containerization using Docker and deployment via AWS ECS or EKS (Kubernetes) - understanding of how to package, deploy, and manage services in containers
- Hands-on CI/CD experience - building and maintaining pipelines using Jenkins, GitHub Actions, or AWS CodePipeline for automated build, test, and deployment across environments
- Experience with unit testing and integration testing frameworks - JUnit, Mockito, Jest, or React Testing Library - and commitment to maintaining meaningful test coverage
- Ability to understand legacy mainframe data structures and business logic (with SME guidance) and translate them into equivalent cloud-native application behavior - the core skill of this migration program
Roles & Responsibilities
- Build the cloud-native replacement applications that take over the business functions currently running on the mainframe - this is the core job; each engineer owns specific modules from design through deployment
- Develop backend microservices using Java and Spring Boot that implement business logic equivalent to existing COBOL programs - working closely with SMEs to understand what the legacy code does and ensuring the new service does it correctly
- Build frontend web UIs using React.js or Angular that replace legacy mainframe screens - designing workflows that are intuitive for business users who are transitioning from character-based interfaces
- Design and build REST APIs that expose migrated business functionality - ensure APIs are secure, versioned, documented in OpenAPI/Swagger, and aligned with the integration contracts agreed with other workstream teams
- Integrate new services with AWS managed services - RDS/Aurora for relational data, DynamoDB for high-throughput use cases, SQS/SNS for async messaging, and Lambda for serverless processing
- Work with the Data Engineer to consume migrated data from AWS target stores - understand source data mappings, validate data in the new schema, and ensure application behavior is correct against migrated datasets
- Write comprehensive unit and integration tests for all delivered code - not as an afterthought but as part of the Definition of Done for every story
- Participate actively in all sprint ceremonies - daily stand-up, sprint planning, backlog refinement, and retrospective - with clear daily updates and early escalation of technical blockers
- Conduct and receive peer code reviews - enforce team coding standards, flag design issues, and treat every review as both a quality gate and a learning opportunity
- Maintain technical documentation as a sprint deliverable - API specs, data flow diagrams, deployment notes, and known issues - so the program does not accumulate undocumented knowledge debt
Salary Range-$100,000-$130,000 a year
