Node.js Backend Engineer

About the Role

We need a Node.js Backend Engineer to build the APIs, services, and data pipelines that power our AI-driven products. You'll design scalable architectures handling millions of requests, integrate with OpenAI and Claude APIs, build real-time WebSocket systems, and own critical infrastructure from database design to deployment. Our backend runs on Node.js, Express/Fastify, PostgreSQL, Redis, and AWS — with heavy AI integration throughout.

What You'll Do

• Design and build RESTful and GraphQL APIs with Node.js and TypeScript
• Architect microservices and event-driven systems for high throughput
• Integrate OpenAI GPT-5, Claude, and custom ML models into backend workflows
• Build real-time features using WebSockets and Server-Sent Events
• Design and optimize PostgreSQL schemas, queries, and migrations
• Implement caching strategies with Redis for performance and rate limiting
• Set up CI/CD pipelines, monitoring, and alerting
• Write comprehensive tests and maintain high code coverage

What We're Looking For

• 4+ years of backend development with Node.js and TypeScript
• Experience designing RESTful APIs and/or GraphQL services at scale
• Strong PostgreSQL or similar relational database expertise
• Experience with message queues (SQS, RabbitMQ, or Redis Streams)
• Familiarity with Docker, CI/CD, and cloud deployment (AWS preferred)
• Understanding of authentication, authorization, and API security best practices
• Experience with monitoring tools (Datadog, New Relic, or CloudWatch)
• Ability to work independently and communicate asynchronously

Nice to Have

• Experience integrating LLM APIs (OpenAI, Claude, Cohere)
• Familiarity with vector databases (Pinecone, Weaviate, Chroma)
• Experience with serverless (AWS Lambda, Vercel Functions)
• Knowledge of Kafka or similar streaming platforms
• Experience building multi-tenant SaaS architectures
