Senior Fullstack Engineer – CargoX (Unified JD)

Nov 11, 2026 ·

About CargoX

CargoX is a UAE-based autonomous logistics company running driverless delivery vans, bots and drones. Our fleet orchestration platform coordinates the full delivery journey, from order creation and dispatch through live vehicle tracking, customer handoff and incident recovery, connecting delivery partners, operators and vehicle makers.

Role overview

Senior Fullstack Engineer owning features end to end, from the backend API to the screens our operations teams and field workers use. You'll join one of two squads (see Squad differences), each a sub-team of two to three engineers owning one product with a business owner.

What you'll do

• Build features across the stack: API and data model, backend logic, and the web or mobile interface.
• Stream live vehicle, order and task updates from backend to screen with low latency.
• Make the client reliable on poor connections (offline-first sync, conflict handling).
• Contribute to the backend that coordinates long-running workflows and vehicle and partner integrations.
• Implement security and monitoring across the stack (multi-tenancy, access control, secure token handling).

How we build

Kotlin and Spring Boot modular monolith on PostgreSQL/PostGIS, Redis and Kubernetes. Web console in TypeScript and Next.js/React; field apps in TypeScript, React Native and Expo. Vehicle and partner integrations via REST, webhooks and MQTT.

Qualifications

• 5+ years building complex production systems, owning features across backend and frontend or mobile; CS degree or equivalent.
• TypeScript with React/Next.js (web) or React Native/Expo (mobile).
• Backend: Java/Kotlin and Spring Boot preferred; distributed systems, concurrency and API design.
• PostgreSQL and real-time communication (WebSockets, MQTT).
• Real-time state management and offline-first sync on the client.
• Automated testing (unit, integration, end-to-end).
• Fluent business English.

What we offer

• XX days holiday + UAE public holidays
• Comprehensive health coverage
• Annual flight allowance
• Free on-site meals
• Relocation support for candidates moving to Abu Dhabi

Squad differences

Both roles are fullstack and share the same backend. The big difference is the screen: a web app on a desk vs a mobile app in someone's hand.

LiveOps Console (Orchestration): the "mission control screen"

• In plain English: builds the web app that operations agents use to watch the whole fleet live on a map and deal with problems, like a stuck robot or a late delivery. Alerts, an incident queue, a supervisor dashboard. Goal: automate most of it so a few hundred agents can run thousands of vehicles.
• Works with: the Head of LiveOps and the agents in the control room.
• CV keywords: React, Next.js, TypeScript, WebSockets, real-time dashboards, Mapbox, PWA, alerting, incident management.
• Good backgrounds: dispatch or operations dashboards at delivery or ride-hailing companies, monitoring or "mission control" tools.

Runner App (RMS & Apps): the "app in the runner's pocket"

• In plain English: builds the phone app human runners use on every shift: their tasks, scanning a QR code to unlock a robot, proof-of-delivery photos, maps, chat and earnings. It's just launching (built by an outside partner), so this person takes it over and scales it to 500+ runners. Next up: an app for warehouse staff loading the robots.
• Works with: the Head of Operations and the runners themselves.
• CV keywords: React Native, Expo, mobile, iOS/Android, App Store releases, offline-first, push notifications, QR/camera, Detox or Maestro.
• Good backgrounds: courier, gig-worker or field-service apps (e.g. delivery driver apps), any team that has shipped and scaled a React Native app in production.
