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€
