React Developer

Project Description

We are building a resilient, secure, production-grade platform of Python backend services, REST APIs, asynchronous processing components, and external integrations, backed by MongoDB. The operational user interface is delivered through React/TypeScript with auditable operations and role-based enterprise user journeys.

Responsibilities

• Own complex operational screens, reusable components, and front-end patterns.
• Integrate REST APIs and manage server state, caching, polling, and error handling.
• Implement consistent UI using the agreed enterprise design system.
• Manage client state and role-based UI behaviour.
• Deliver accessible interfaces aligned to WCAG principles.
• Create component, unit, and integration tests.
• Optimize performance and troubleshoot complex UI/API behavior.
• Contribute to design decisions and support Junior engineers.

Must Have Skills

Experience: 10+ years.

• Strong production SPA development in React and TypeScript: hooks and reusable components.
• Complex operational UI: dashboards, tables, status/exception displays and changing operational data.
• REST, async handling, caching, polling, loading/error states and correct stale-vs-fresh data presentation with timestamps.
• Translating designs into consistent reusable enterprise components (Nitro or comparable design system).
• State management: Redux Toolkit, Zustand or comparable.
• Hands-on accessible UI delivery (WCAG 2.2 AA) – not awareness only.
• Component/unit/integration testing and maintainable code.
• Role-based journeys (authentication/RBAC) and secure enterprise UI behaviour.
• Responsible use of AI coding/testing assistants.
• Independently owns complex screens and front-end patterns, contributes to design decisions and diagnoses complex UI/API issues.
