React.js Developer

We are looking for a Frontend Architect who understands that a UI is only as good as its performance. At KoiReader, you won't just be building static websites; you will be building the "Mission Control" for Industrial AI. You will design complex, real-time dashboards that visualize massive streams of supply chain data, live camera feeds, and AI analytics using React, GraphQL, and TypeScript. We need a builder who obsesses over re-renders, bundle sizes, and creating intuitive UX for complex operational problems.

Component Architecture: Architect and maintain a scalable, reusable React Component Library. You ensure that our UI codebase remains modular and clean as the product grows.

Real-Time Visualization: Build high-performance interfaces that handle live data updates via GraphQL Subscriptions and Pub/Sub. You make sure the dashboard updates instantly without freezing the browser.

Performance Engineering: Diagnose and fix rendering bottlenecks. You understand how the React Virtual DOM works and how to optimize large datasets using virtualization.

State Management Strategy: Design robust state management flows using React Hooks, Context API, or Apollo Client. You ensure data consistency across complex multi-step workflows.

Tech Stewardship: Research and introduce new tools (e.g., migrating to Vite, implementing new CSS-in-JS patterns). You set the standard for code quality and mentor junior developers.

Full Stack Integration: Work closely with the Backend team to design efficient GraphQL schemas that reduce over-fetching and improve frontend performance.

React Mastery: Deep expertise in React.js (Hooks pattern). Class components are history to you.

Type Safety: Strong proficiency in TypeScript. You rely on types to catch bugs before they hit production.

Data Layer: Expert knowledge of Apollo Client and GraphQL. You know how to manage local cache and remote data seamlessy.

Styling: Proficiency with Styled Components or modern CSS-in-JS libraries. You can implement complex designs pixel-perfectly.

Build Tooling: Experience configuring Webpack or Vite. You know how to code-split and tree-shake your bundle.

Auth Workflows: Experience implementing secure authentication using JWT and OAuth2.

DevOps Awareness: Knowledge of Docker and Kubernetes. You can troubleshoot a frontend container.

Mobile Flexibility: Understanding of React Native (since we have mobile apps, being able to share logic is a plus).

Visualization: Experience with D3.js, Recharts, or mapping libraries.

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.
