Job description

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 hiring a mid-level full stack engineer whose primary responsibility is frontend development: the React Native

driver app and Mapbox GL JS map features, as well as an admin portal. Backend work in .NET might be a

secondary part of the role.

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

• Work within an actor-model distributed backend (built on Microsoft Orleans) designed by the tech lead

Requirements

• 2–5 years of professional software engineering experience

• Strong experience with React Native for mobile app development

• Strong experience with Mapbox GL JS or a comparable mapping/geospatial library (Leaflet, Google Maps

SDK)

• Working proficiency in C#/.NET — API design, services, data pipelines

• Comfort working with realtime/streaming data (WebSockets, telemetry, sensor data)

• Strong written and spoken English for daily collaboration with a distributed team

Nice to Have

• Familiarity with distributed systems / actor-model concepts (e.g., Orleans, Akka)

• Experience with BLE positioning or beacon technology

• Background in industrial, logistics, or IoT/telemetry domains

• Security-conscious development practices (authentication, PII handling)
