Backend Developer

We are looking for a driven Backend Developer who understands that a platform is only as powerful as the engine running it. At KoiReader, you won't just be building standard CRUD apps; you will be building the robust data pipelines and APIs that power the "Mission Control" for Industrial AI. You will design and maintain highly scalable backend services that process massive streams of supply chain data and AI analytics using Node.js, TypeScript, Apollo GraphQL, WebSocket, PostgreSQL, and Redis. We need a builder who cares about query optimization, API latency, Security, Documentation and writing clean, scalable code.

Key Responsibilities :

Type-Safe Architecture: Write clean, modular, and maintainable backend code utilizing TypeScript. You rely on strict typing to catch bugs before they reach production.

Cross-Functional Collaboration: Work closely with the Frontend, AI, and DevOps teams to integrate computer vision data and deploy seamless end-to-end features.

Skills & Requirements :

Backend Foundation: Hands-on experience building backend services with Node.js and Express/Fastify.
Type Safety: Strong proficiency in TypeScript. You understand how to build robust, typed backend services.
GraphQL Expertise: Solid experience with Apollo GraphQL (Server). You know how to design efficient schemas, write resolvers, and avoid the N+1 query problem.
Relational Databases: Hands-on experience with PostgreSQL. You are comfortable with complex joins, migrations, and basic query optimization.
In-Memory Datastores: Experience using Redis for caching, session management, or pub/sub mechanisms.
Version Control: Solid understanding of Git and collaborative PR workflows.

DevOps Awareness: Basic knowledge of Docker containerization and CI/CD pipelines.
Authentication: Experience implementing JWT, OAuth2, or SSO integrations.

What We Offer :

Meritocracy: A candid startup culture where the best ideas win.
The Playground: Access to the latest NVIDIA Hardware and cutting-edge Generative AI tools.
Ownership: Lead a performance-oriented team driven by autonomy and open to experiments.
Impact: Design systems for high accuracy and scalability that physically move the global supply chain.
