About this role
Alongside partners with organizations to drive digital transformation and build high-performing tech teams.
We're building a real-time facility navigation and asset-tracking platform for industrial and logistics sites - GPS/BLE-based positioning, live forklift and asset overlays, zone/dwell analytics, and a driver-facing mobile app, backed by a distributed-systems (actor-model) backend.
The Role
We're looking for a Fullstack Engineer with a strong frontend focus to join the development of a real-time, data-driven platform.
Most of your work will focus on the React Native driver app, Mapbox GL JS features and the web-based admin portal, while also contributing to C#/.NET backend services when needed.
You'll work on interactive, real-time experiences involving live location, sensor and asset data, with a strong focus on performance and usability.
Responsibilities: Frontend (Primary)
- Build and maintain the React Native driver app: QR onboarding/consent flows, GPS/BLE data display
- Implement Mapbox GL JS features: live position overlays, zone/dwell visualization, realtime map layers
- Own frontend performance and reliability for realtime, sensor-driven UI
Responsibilities: Backend (Secondary)
- Build and maintain RESTful APIs and backend services in C#/.NET
- Support GPS/BLE positioning data ingestion pipelines
- Support telemetry ingestion and zone/dwell analytics processing
