Senior Frontend Engineer – IoT

This is a fully remote position, open to applicants in Pakistan.

📋 Description

• Develop the IoT platform web application from the ground up, including a device management portal, real-time monitoring dashboards, an alert management interface, a rule configuration UI, an OTA management screen, and multi-tenant admin panels.

• Implement real-time telemetry visualization using WebSocket and MQTT-over-WebSocket to ensure live sensor values and alerts update without requiring a page refresh, even under high concurrency.

• Create an interactive geospatial device map to display real-world asset locations and statuses using Mapbox GL or Leaflet.

• Design time-series chart components, including line charts, gauges, heat maps, and bar charts, with configurable thresholds and anomaly overlays.

• Establish the multi-tenant admin layer, encompassing tenant creation, user management, role assignment, data scope controls, and white-label capabilities.

• Develop a device onboarding wizard that offers a step-by-step flow, simplifying protocol complexity for non-technical operators.

• Create a widget-based dashboard builder with a drag-and-drop interface, allowing end users to assemble custom monitoring views.

• Design alert and rule management interfaces featuring a visual rule builder, acknowledgement workflows, escalation chain setup, and a historical alert log.

• Construct a reusable component library from Day 1, ensuring all UI elements are abstracted without creating one-off components.

• Take ownership of frontend performance, ensuring that high-frequency data streams do not lead to memory leaks, frame drops, or browser crashes by implementing virtualization, throttling, and WebWorker offloading as necessary.

• Write thorough tests, including unit (Vitest/Jest), integration (React Testing Library), and E2E (Playwright) tests that encompass all critical user journeys.

• Set up i18n scaffolding from the outset, as the platform serves regions including MENA, South Asia, and Europe, with a requirement for Arabic RTL support.

• Manage and maintain the frontend CI/CD pipeline, automating linting, testing, building, and deployment to AWS S3/CloudFront.

• Document all component APIs, usage patterns, and integration guides within the knowledge base.
