Role: Full Stack Developer | Department: Engineering - Software & QA | Industry: IT Services & Consulting | Education: UG: Any Graduate Role & responsibilities Full Stack Java/J2EE Developer (AWS Serverless) Role Summary We're looking for a hands-on Full Stack Java/J2EE Developer with proven experience building serverless applications on AWS. You'll own end-to-end delivery-designing RESTful APIs, implementing microservices using Spring Boot, and deploying scalable, secure event-driven workloads with AWS Lambda, API Gateway, DynamoDB, SQS/SNS, Step Functions, and EventBridge. Should be comfortable with IaC (CDK/CloudFormation/SAM), automated testing, CI/CD, and production observability. Key Responsibilities Design & Build: Develop scalable microservices and serverless APIs using Java 11+/17, Spring Boot, API Gateway, and AWS Lambda; implement data models on DynamoDB and/or RDS (Aurora/MySQL/PostgreSQL) using JPA/Hibernate where applicable. Event-Driven & Orchestration: Implement asynchronous workflows with SQS/SNS, EventBridge, and Step Functions; apply idempotency, DLQs, and retry strategies. Serverless Best Practices: Implement CI/CD (e.g., GitHub Actions, Jenkins, CodePipeline); integrate security scanning (SCA/SAST/DAST) and secrets management (AWS Secrets Manager/Parameter Store). Data & Caching: Use DynamoDB patterns (GSIs, TTL, partitions), S3 for object storage, ElastiCache/Redis for caching, and OpenSearch (optional) for search and analytics. Security & Compliance: Implement OAuth2/OIDC, JWT, and AWS Cognito or enterprise IdP integration; ensure encryption in transit/at rest, handle PII, and align with OWASP and org security standards. Testing & Quality: Write unit/integration tests (JUnit, Mockito, Testcontainers), contract tests (e.g., Pact), and UI tests (e.g., Cypress/Playwright); maintain high coverage and code quality (SonarQube). Observability: Instrument with CloudWatch Logs & Metrics, structured logging, X-Ray traces, and dashboards/alerts (CloudWatch/Datadog/New Relic). Collaboration: Work closely with Product, QA, Security, and Ops; participate in code reviews, design sessions, and agile ceremonies. Required Skills & Experience 6-11 years of experience in Java/J2EE full-stack development, including Spring Boot, REST APIs, Gradle, and JPA/Hibernate. 3+ years building production systems on AWS, including Lambda, API Gateway, DynamoDB, S3, CloudWatch, IAM, and at least one of SQS/SNS/Step Functions/EventBridge. Practical experience with IaC (AWS CDK, CloudFormation, or SAM) and CI/CD pipelines. Strong understanding of microservices, event-driven architectures, distributed systems, and serverless patterns (e.g., saga/orchestration vs. choreography). Solid grounding in security (OAuth2/OIDC, JWT, secrets, IAM), testing, and observability in cloud-native environments. Excellent problem solving, communication, and collaboration skills in agile teams.
