Senior Android Backend Developer - Advanced Security Features & Api Integration (Phase 3)

We are shortlisting a Senior Android Developer to implement advanced features into an existing, fully stable background telemetry and Acoustic DSP application. The core service architecture and focus management are already complete. Your job will be strictly backend logic, data routing, and API integrations.Technical Scope:Dynamic GPS Emergency Routing: Integrate local emergency dispatch logic. The app must fetch live gps coordinates and dynamically route the sos call trigger to local emergency numbers (e.g., Local police/medical services) based on current municipal bounds.WebPay/Transbank SDK Payment Wall: Implement a modular billing restriction handler. At day 90, the system must trigger an interactive payment wall restricting remote socket transmissions, forcing a local micro-payment package processing loop.rtsp/hls media stream bridge: connect a secure video player module inside the app to hook into municipal public security camera live feeds via rtsp/hls protocols upon remote authentication.Requirements:High-level expertise in Android Background Services, Foreground Types, and network socket management.Experience with payment Sdks and video streaming integration.⚠️ mandatory technical screening question:to filter out automated ai bots, you must answer this specific question in your application:when streaming external public security cameras via rtsp/hls inside an android application running an active foreground service, how will you manage the network sockets and hardware-accelerated video decoding to ensure the stream connection doesn't trigger an application not responding (anr) error or drop the high-priority background audio processing? be technically specific. Generic templates will be instantly deleted.
