SDE Backend

Job Description

We’re looking for a Backend Developer who loves building scalable, secure systems — and is curious about how AI can supercharge product experiences. You’ll work closely with product, design, and AI teams to architect backend systems that power real-world applications using LLMs and Retrieval-Augmented Generation (RAG).

Strong working knowledge of Node.js, Express, NestJS, or equivalent backend frameworks

Deep understanding of RESTful and GraphQL APIs and event-driven architecture

3+ years of experience building and scaling backend systems from scratch

Hands-on experience with authentication, validation, and authorization flows (JWT, OAuth2, RBAC, etc.)

Strong database knowledge — PostgreSQL, MongoDB, Redis, message queues (RabbitMQ, Kafka)

Experience with TypeScript, Prisma / Sequelize, Swagger / Postman for API documentation

Familiar with Docker, Kubernetes, AWS / GCP, and CI / CD pipelines

Bonus : experience integrating LLM APIs (OpenAI, Anthropic, Gemini, etc.) and vector databases (Pinecone, Weaviate, Qdrant, FAISS)

Understanding of RAG architecture, embedding pipelines, and prompt orchestration

You care about performance, clean architecture, and production reliability

You love collaborating across engineering, design, and product to bring ideas from 0 → 1

Requirements

You’re amazing at Node.js, system architecture, and API design

You’ve built or contributed to production-grade systems handling auth, caching, rate limiting, and monitoring

You’re curious about how AI products work under the hood — from LLM prompts to retrieval pipelines

You’ve dabbled with or deployed AI-powered APIs, know what vector stores do, and can wire them into real applications

You’re comfortable designing modular service architectures that scale with product and data growth

You believe in test-driven development, clean documentation, and reproducible environments

You can discuss trade-offs with PMs and designers — and back your opinions with data and pragmatism

You bring a maker’s mindset — bias for action, clarity in communication, and passion for building something meaningful

Requirements

This role is for you, if (Qualifications & Req) : 1. You're a proven builder who owns the full charter. You love taking an idea from 0 to 1. You have a track record of owning the entire product lifecycle—from initial research and creation to a successful GTM launch. You've likely honed this skill for at least 3 years in a modern, internet-first company, and your elegant project management keeps everything on track. 2. You're a gifted storyteller who builds transformation products. You have a special talent for making complicated things feel simple, and you know that great documentation is a key part of the story. You don't just share information; you build learning experiences that change the way people think and help them achieve their goals. 3. You're an AI insider with deep curiosity. Your obsession with the AI space is matched by your skill in conducting deep user, product, and market research. You don't just follow trends; you understand the 'why' behind them and can translate raw insights into a clear point of view and a concrete plan. 4. You're an owner with a startup mentality. The prospect of joining a small, fast-moving team energizes you. You thrive in ambiguity and want ownership. Accountability doesn't scare you; it motivates you. You are driven by impact, not tasks, and you're obsessed with finding fast, efficient ways to create value for our members. Bonus Points : Previous startup experience. You have thrived in an unstructured, ambiguous environment.
