About The Role

We’re looking for a Senior Full Stack Developer with strong backend expertise in Java (Micronaut or Spring Boot) and solid understanding of serverless architectures on AWS using Lambda and API Gateway. You’ll work on building scalable, event-driven microservices and modern APIs that power high-impact applications. Experience with React on the frontend is a bonus and adds significant value.

Key Responsibilities

• Design, develop, and maintain backend services using Java Micronaut or Spring Boot.
• Build and deploy serverless components using AWS Lambda, integrating with API Gateway, DynamoDB, S3, etc.
• Architect and optimize RESTful APIs that support secure, performant, and scalable user interactions.
• Understand and implement best practices around API Gateway routing, throttling, security, and custom authorizers.
• Collaborate with frontend developers to integrate APIs with React-based user interfaces (if required).
• Write clean, testable, and efficient code with good coverage using JUnit/TestNG.
• Participate in code reviews, design discussions, and sprint planning sessions.
• Optimize backend performance, error handling, and observability (logs, metrics, tracing).
• Contribute to CI/CD workflows and cloud deployments (Code Pipeline, GitHub Actions, etc.).
  
  

• 5–8 years of professional software development experience.
• Strong experience with Java and Micronaut or Spring Boot frameworks.
• Solid hands-on experience with AWS Lambda and event-driven architectures.
• Deep understanding of how API Gateway works — including integration types, authorizers, throttling, and custom domains.
• Familiarity with cloud services like S3, DynamoDB, CloudWatch, and IAM.
• Experience building scalable and secure RESTful APIs.
• Knowledge of CI/CD pipelines, Git workflows, and infrastructure automation.
• Strong debugging and troubleshooting skills.
  
  

• Frontend development experience using React.js or similar frameworks.
• Experience with Terraform or other infrastructure-as-code tools.
• Familiarity with Cognito, SNS/SQS, and event-driven AWS patterns.
• Knowledge of testing frameworks (e.g., Cypress for frontend, Postman for API tests).
• Exposure to containerization (Docker) and understanding of DevOps workflows.
  
  

• A collaborative and agile team environment.
• Opportunity to work with modern tech stacks and serverless architectures.
• Flexibility to contribute across backend and frontend (full stack).
• Remote-friendly culture and flexible working hours.
• Ownership of features and solutions from architecture to deployment.
