Indian AI Community

Senior Backend Engineer

Node.js  •  AI-Native Software Development

Experience: 4–5 years  |  Type: Full-time  |  Location: On-site / Hybrid

About the Role

We are looking for a Senior Backend Engineer who builds fast, reliable systems and treats AI as a first-class engineering tool — not a buzzword. You will design and ship production-grade backend services in Node.js, and integrate modern AI capabilities (LLMs, RAG, agents, embeddings) into real product workflows. This is a hands-on role for someone who writes clean code, owns systems end-to-end, and uses AI to move faster without compromising quality.

What You'll Do

•     Design, build, and scale backend services and REST/GraphQL APIs using Node.js (Express / NestJS / Fastify).

•     Integrate LLM-powered features into products — RAG pipelines, semantic search, chat/agent workflows, and structured AI outputs.

•     Work with vector databases (pgvector, Pinecone, Weaviate, Qdrant) and embedding models for retrieval and recommendation.

•     Architect data layers across PostgreSQL, Redis, and NoSQL stores, with a focus on performance and low latency.

•     Build and consume APIs from AI providers (OpenAI, Anthropic, Bedrock, etc.) with proper cost, latency, and reliability controls.

•     Use AI-assisted development tools (Copilot, Claude, Cursor) to ship higher-quality code faster.

•     Write tests, set up CI/CD, and own services in production — monitoring, logging, and incident response included.

•     Collaborate with product, frontend, and data teams to turn requirements into well-architected systems.

What We're Looking For

Core Requirements

•     4–5 years of professional backend development experience, primarily in Node.js / TypeScript.

•     Strong grasp of JavaScript/TypeScript fundamentals, async patterns, and event-driven architecture.

•     Solid experience designing and scaling RESTful and/or GraphQL APIs.

•     Proven experience with relational and NoSQL databases (PostgreSQL, MongoDB) and caching with Redis.

•     Hands-on experience integrating at least one LLM/AI API into a real product or feature.

•     Comfortable with Docker, Git, and CI/CD pipelines.

•     Understanding of system design, scalability, and security best practices.

AI-Native Skills (Strongly Preferred)

•     Practical experience building RAG pipelines or retrieval systems with vector databases.

•     Familiarity with prompt engineering, function/tool calling, and structuring reliable LLM outputs.

•     Experience with AI frameworks such as LangChain, LlamaIndex, or the Vercel AI SDK.

•     Awareness of LLM cost optimization, token management, streaming, and evaluation/guardrails.

•     Daily use of AI coding assistants as part of a real engineering workflow.

Nice to Have

•     Cloud experience (AWS / GCP / Azure) and infra-as-code.

•     Experience with WebSockets / real-time systems and message queues (SQS, Kafka, RabbitMQ).

•     Exposure to Kubernetes, serverless, or event-driven microservices.

•     Contributions to open source or a strong public engineering presence.

What You Bring as a Person

•     Ownership mindset — you ship and you maintain what you ship.

•     Pragmatic about AI — you know when to use it and when not to.

•     Clear communicator who can explain technical trade-offs simply.

•     Curious and fast-learning in a quickly evolving AI landscape.

Why Join Us

Work on modern, AI-first products with real-world scale. Ship features that use the latest in applied AI, with the autonomy to make architectural decisions and the support of a team that values clean engineering. Competitive compensation, growth opportunities, and a culture that rewards builders.

To apply, send your resume, GitHub/portfolio, and a short note on an AI feature you've shipped.
