Lead Full-Stack Engineer - API and GraphQL - SGWS

Full Stack Engineering Position

Must have excellent, clear communication

9+ years of experience in an hands on role in Full Stack engineering focused on API development in GraphQL (Ariadne) and RESTful services Hands on experience with Node.js (Express/Nest.js), FastAPI (Python), and Golang.

API Management - API Gateway, APIGEE & Designing and deploying APIs as part of a microservices architecture.

React, HTML, JS, NodeJS, Python, Lambda, CI/CD & RESTful API and GraphQL development

Responsibilities:

• Design, develop, and maintain scalable RESTful APIs and GraphQL APIs using modern frameworks and best practices.
• Develop backend services using Node.js (Express/Nest.js), FastAPI (Python-based services), Ariadne (GraphQL APIs), and Golang (Streaming services).
• Integrate with Databricks to expose and manage OLAP (Online Analytical Processing) workloads, enabling API-driven data querying and analytics at scale.
• Architect APIs following metadata-driven design principles, ensuring that data can be dynamically exposed to users inside or outside the system while maintaining dynamic authentication mechanisms.
• Deploy and scale API services using AWS Lambda, Kubernetes (EKS), and AWS Bedrock for serverless and microservices-based architectures.
• Implement authentication and authorization best practices (OAuth2, JWT, API Gateway) while supporting dynamic authentication models based on user roles and access control.
• Design and optimize database interactions using SQL/NoSQL databases (MongoDB, PostgreSQL, DynamoDB).
• Develop CI/CD pipelines for automated API deployment using AWS services (CodePipeline, Bedrock, CloudFormation).
• Monitor and improve API performance, logging, and error handling using Prometheus, Grafana, and ELK stack.
• Work on AI-driven API integrations including Recommender Systems, LLM-based AI Agents, and AI-powered Image & Video Processing workflows.
• Collaborate with front-end engineers, data scientists, and DevOps teams to ensure seamless API integration and scalable deployments.

Requirements:

• 9+ years of experience in API development with GraphQL (Ariadne) and RESTful services.
