Job summary

Saarthee, a global Data Analytics and AI consulting company, seeks a Full Stack Developer to design, develop, test, and deploy scalable cloud-native apps on AWS with multi-tier architecture. You will work across front-end and back-end stacks (Angular/React, TypeScript, Node.js), build RESTful APIs, and enable secure auth and CI/CD.

The role supports a hybrid work model in Gurugram and embraces GenAI-driven features.

Qualifications

• Strong experience in full stack development using Angular or React, TypeScript, Node.js, and RESTful APIs.
• Proficiency with core AWS services: Lambda, S3, EC2, API Gateway, DynamoDB, RDS, CloudFormation, ECS/Fargate, CloudWatch, IAM.
• Skilled in serverless and containerized application design using AWS, Docker, and ECS.
• Experience building and consuming RESTful APIs, integrating with upstream/downstream systems using Node.js or Spring Boot.
• Strong database experience across Amazon RDS (MySQL/PostgreSQL), DynamoDB, solid SQL and NoSQL modeling skills.
• Experience implementing secure authentication/authorization using AWS Cognito and JWT.
• Hands-on experience with CI/CD automation using AWS CodePipeline, CodeBuild, Jenkins, or GitHub Actions.
• Exposure to GenAI/agentic AI concepts (LLM APIs, RAG, LangChain/LangGraph) is a strong plus.

Responsibilities

• Build robust, secure, and high-performance cloud-native solutions on AWS, spanning front-end (Angular/React, TypeScript) and back-end (Node.js, RESTful APIs).
• Implement multi-tier architectures and RESTful microservices, integrating with upstream and downstream systems.
• Design and deploy serverless and containerized applications using AWS Lambda, ECS/Fargate, and Docker.
• Manage databases across Amazon RDS (MySQL/PostgreSQL), DynamoDB, and Aurora, covering both SQL and NoSQL data modeling.
• Implement secure authentication and authorization using AWS Cognito, OAuth2.0, and JWT.
• Build and maintain CI/CD pipelines using AWS Code Pipeline, Code Build, Jenkins, and GitHub Actions.
• Apply testing frameworks and backend testing tools to ensure code quality and reliability.
• Explore and apply GenAI capabilities — LLM APIs, retrieval-augmented generation (RAG), and agentic workflows — where they add value to product features.
