Role Description We need a Senior Frontend Engineer to build the web application that sits on top of our IoT platform — a real-time, data-dense monitoring and management interface used by facility managers, fleet operators, and enterprise administrators. This is not a marketing website or a standard CRUD app. It renders thousands of live data points simultaneously, handles high-frequency WebSocket streams, and serves multiple industries from a single configurable codebase. Qualifications - 5–8 years of frontend engineering with a portfolio of real-time, data-rich applications — live product links are required at interview; no portfolio = no interview ⚑ PORTFOLIO REQUIRED - Expert React with TypeScript — you design component hierarchies and state architecture, not just consume component libraries; Next.js strongly preferred ⚑ NON-NEGOTIABLE - Production experience shipping real-time applications using WebSocket or MQTT-over-WebSocket in the browser — not just theoretical knowledge ⚑ NON-NEGOTIABLE - Data visualisation library proficiency: D3.js, ECharts, Recharts, or ApexCharts — able to build custom chart types beyond out-of-the-box defaults - Geospatial mapping for asset visualisation: Mapbox GL JS, Leaflet, or Deck.gl - State management in complex real-time applications: Redux Toolkit, Zustand, or TanStack Query - Frontend performance optimisation: virtualised lists, memo and callback strategies, lazy loading, Web Workers for CPU-intensive work - Solid understanding of REST and GraphQL API integration, auth token handling, and error boundary patterns - Remote work discipline: proactive async communication, self-documentation, minimum 4 hours daily overlap with UAE working hours ⚑ REMOTE DISCIPLINE Requirements - Build the IoT platform web application from scratch: device management portal, real-time monitoring dashboards, alert management interface, rule configuration UI, OTA management screen, multi-tenant admin panels - Implement real-time telemetry rendering using WebSocket and MQTT-over-WebSocket — live sensor values and alerts must update without page refresh at high concurrency - Build an interactive geospatial device map showing real-world asset locations and statuses using Mapbox GL or Leaflet - Develop time-series chart components: line charts, gauges, heat maps, bar charts, with configurable thresholds and anomaly overlays - Build the multi-tenant admin layer: tenant creation, user management, role assignment, data scope controls, and white-label capability - Implement a device onboarding wizard: step-by-step flow that abstracts protocol complexity for non-technical operators - Build a widget-based dashboard builder: drag-and-drop interface for end users to compose custom monitoring views - Build alert and rule management interfaces: visual rule builder, acknowledgement workflows, escalation chain setup, historical alert log - Build a reusable component library from Day 1 — all UI elements abstracted, no one-off components - Own frontend performance: high-frequency data streams must not cause memory leaks, frame drops, or browser crashes — implement virtualisation, throttling, and WebWorker offloading where needed - Write comprehensive tests: unit (Vitest/Jest), integration (React Testing Library), E2E (Playwright) covering all critical user journeys - Implement i18n scaffolding from the start — the platform serves MENA, South Asia, and Europe; Arabic RTL support is required - Own and maintain the frontend CI/CD pipeline: automated lint, test, build, deploy to AWS S3/CloudFront - Document all component APIs, usage patterns, and integration guides in the knowledge base Company Description
