Job Description

Full Stack Engineer

Flatgigs

• Build multi-tenant services from scratch: device registration/auth, alert/rule engines, notifications, and device shadow (last-known-state) services. • Implement the MQTT ingestion path (EMQX broker), normalize telemetry, and persist it to time-series storage and Aurora PostgreSQL (with strict row-level security). • Develop versioned REST APIs (OpenAPI) and real-time delivery paths via WebSockets for high-concurrency dashboard updates. • Build the platform web application in Next.js + TypeScript, including monitoring dashboards, onboarding wizards, and multi-tenant admin portals. • Render live telemetry and time-series visualizations (line, gauge, maps) without lag, page refreshes, or memory leaks. • Make independent UX choices in the absence of a designer; maintain a reusable component library from Day 1 with i18n scaffolding (Arabic RTL support). • Provision and maintain AWS environments (UAE region me-central-1 for data residency) using Terraform. No click-ops. • Set up GitHub Actions CI/CD pipelines, operate core infrastructure (Kafka, Redis, InfluxDB), and define horizontal scaling strategies for hundreds of thousands of devices. • Work autonomously with proactive documentation (ADRs, runbooks) and a minimum 4-hour daily overlap with UAE working hours.

Job Requirements

  • 5–9 years of full-stack engineering shipping production applications (portfolio required showing deep execution on both sides).
  • Expert Frontend: React/Next.js with TypeScript; proven experience handling high-frequency data streams and virtualized lists via WebSockets. (Non-Negotiable)
  • Strong Backend: Production services in Node.js/TypeScript and/or Python; strong data modeling and relational performance (PostgreSQL). (Non-Negotiable)
  • IoT & Messaging: Genuine literacy in MQTT protocols (topics, QoS, LWT) and device connectivity concepts. (Non-Negotiable)
  • Cloud & DevOps: Hands-on AWS infrastructure deployment and GitOps-driven Terraform workflows.
  • Data Viz: Proficiency in D3.js, ECharts, or similar to build custom chart types and geospatial device maps.
