Data Engineer

We are recruiting for a highly skilled Senior API Engineer to join our dynamic engineering team in a remote, long-term contract role to design, develop, and maintain scalable RESTful and GraphQL APIs within a modern microservices architecture. This role involves working with cutting-edge technologies including Node.js, FastAPI, AWS Lambda, EKS, GraphQL (Ariadne), and API Gateway, as well as CI/CD pipelines and advanced data systems such as Databricks. As a key contributor, you will collaborate across front-end, backend, data science, and DevOps teams to build robust, secure, and highly performant APIs that power mission-critical applications and AI-powered workflows. Responsibilities: • Design, develop, and deploy scalable RESTful and GraphQL APIs using Node.js (Express/Nest.js), FastAPI (Python), Ariadne, and Golang. • Implement APIs as part of a microservices architecture with a focus on API Gateway and APIGEE management. • Integrate with Databricks to expose and manage OLAP workloads for large-scale data analytics. • Architect APIs using metadata-driven design principles, supporting dynamic authentication and flexible data exposure. • Deploy services using AWS Lambda, Kubernetes (EKS), and AWS Bedrock to support serverless and scalable microservices. • Implement and manage authentication and authorization using OAuth2, JWT, and API Gateway. • Design and optimize data access with MongoDB, PostgreSQL, and DynamoDB. • Build and maintain CI/CD pipelines using AWS CodePipeline, CloudFormation, and Jenkins/GitHub Actions. • Monitor API performance and reliability using Prometheus, Grafana, and ELK Stack. • Work on AI/ML API integrations, including Recommender Systems, LLM-based Agents, and AI-powered image/video processing workflows. • Collaborate closely with front-end developers (React, HTML, JS), data scientists, and platform teams to ensure smooth integrations and deployments. Requirements: • 5+ years of hands-on experience with API development using RESTful services and GraphQL • Strong proficiency in: • Node.js (Express/Nest.js) • FastAPI (Python) • GraphQL development and architecture • EKS (Kubernetes) • Authentication and Authorization (OAuth2, JWT, API Gateway). • Experience with AWS Lambda, EKS (Kubernetes), and AWS Bedrock. • Deep understanding of authentication/authorization frameworks: OAuth2, JWT, API Gateway. • Proven experience in building metadata-driven API frameworks with dynamic auth models. • Solid knowledge of Databricks and OLAP workloads for data analytics via APIs. • Hands-on with both SQL and NoSQL databases (MongoDB, PostgreSQL, DynamoDB). • CI/CD expertise using tools like AWS CodePipeline, CloudFormation, Jenkins, and GitHub Actions. • Proficient in API testing and debugging with tools like Postman, Newman, Jest, Mocha, and PyTest. • Strong monitoring and observability experience with Grafana, Prometheus, and the ELK stack. • Experience with GraphQL Federation and Apollo Server. • Familiarity with AI/ML APIs, LLM-based chatbots, and platforms like OpenAI, Hugging Face, LangChain. • Background in streaming technologies like Kafka, WebSockets, or Golang-based streaming services. • Exposure to AI-powered data mapping, recommendation engines, and real-time data processing APIs.
