Our first pilot hospital is planned to go live within six months. Technology Stack: TypeScript, React, TanStack Query, Vite, NestJS, PostgreSQL 16, AWS and Playwright. What You Will Build You will work on a large, forms-heavy hospital application covering areas such as: Patient registration and front office Outpatient workflows and queues Billing and cashier operations Laboratory and radiology Pharmacy and stores Administration and master data You will also help build reusable frontend foundations that can support more than 200 screens across multiple hospitals. This includes: Shared React components and reusable UI patterns Design tokens and hospital-specific theming High-performance forms and data-heavy screens UI extension points where optional AI plug-ins can display recommendations Keyboard-first workflows designed for staff working continuously throughout the day Reliable print layouts for hospital documents and operational workflows Responsibilities Build production-grade applications using React and TypeScript. Develop complex forms with nested fields, conditional logic, validation and autosave. Build responsive, reusable and maintainable UI components. Work with large datasets and optimise screens for speed and usability. Own frontend data-fetching, caching, server-state and optimistic-update patterns. Make appropriate decisions about local, server and global application state. Improve frontend performance using techniques such as virtualisation, memoisation and bundle optimisation. Measure performance before making optimisation decisions. Work directly with designers and translate Figma designs into practical production interfaces. Challenge designs constructively when they may negatively affect usability or workflow efficiency. Meet agreed accessibility and frontend performance standards. Write component and frontend tests. Support the QA Engineer's Playwright automation suite. Build and maintain print-friendly layouts. Participate in code reviews and work within a trunk-based development process.
