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)

Benefits

  • Remote work (Portugal-based)
  • Estimated project duration: 19 weeks
  • Full-time schedule: 8 hours per day, with mandatory availability for at least 4 hours
  • Freelance / Service Agreement
  • Hourly Rate: 31€ - 33€
