Looking for strong professionals for the iOS developer role to the Mobile solutions department.


About the project:

A connected pet-safety platform combining GPS geofencing, real-time location, training workflows, and multi-device management. 

The scope of work for the project: end-to-end backend on Azure, mobile application development (Xamarin + native), firmware for BLE/LTE/Wi-Fi, and the Angular admin portal.

Tech part:

The system includes a .NET cloud backend on Azure (AKS/Functions, API Gateway, IoT Hub/MQTT, Event Hub, Redis cache, SQL/Cosmos for telemetry & config, Blob for media), a rules engine for geofence/alerts, OTA update pipeline, webhook/Push/SMS notifications, analytics, and CI/CD with observability (App Insights/Prometheus-Grafana).

Mobile apps are built with Xamarin and native stacks (iOS/Android) consuming REST/GraphQL APIs and background location services.

Device firmware integrates BLE for pairing/provisioning, LTE for wide-area tracking, and Wi-Fi for home connectivity, with secure boot, DFU/OTA, and power-management. An Angular admin console provides fleet/user/subscription management, policy editing, and live device dashboards.
