Responsibilities

• Develop and maintain the Android edge application, using modern Android foundations (Kotlin, Jetpack Compose, Coroutines/Flows, Clean Architecture).
• Build real-time video streaming features (WebRTC, RTSP, low-latency media pipelines) optimized for edge-device performance.
• Implement geospatial and mapping capabilities, including live overlays, multi-device syncing, and sensor integration.
• Integrate with backend and peer-to-peer systems, ensuring robust communication between devices and cloud services.
• Working on a fleet of Android edge devices, on a large scale.
• Optimize for performance, reliability, and power constraints—especially in challenging or degraded network environments.
• Prototype and explore bleeding-edge tools, libraries, and architectures, bringing fresh perspectives and ideas.
• Collaborate with product, hardware, and field teams to understand operator realities and deliver solutions that work in the real world.
• Own complex technical challenges, especially those requiring creative, first-principles thinking or unconventional solutions.

• Proficiency with modern Android patterns: Jetpack Compose, Coroutines, Flows, Clean Architecture, and reactive principles.
• Demonstrated ability to learn new technologies quickly and work outside your comfort zone.
• Strong debugging, analytical, and problem-solving skills in complex systems.
• Experience building production-grade Android applications with a focus on performance, stability, and readability.
  
  

• Experience with video streaming technologies: WebRTC, RTSP, RTP, codecs, media servers.
• Knowledge of networking, low-level, or systems work.
• Background in real-time or mission-critical applications.
• Familiarity with peer-to-peer connectivity, Bluetooth, Wi-Fi Direct, or hybrid connectivity solutions.
• Experience with cloud technologies, distributed systems, or edge+cloud hybrids.
• Exposure to mapping, GIS, telemetry, or sensor fusion
