Internal candidates are also encouraged to apply. Primary Objective: We are looking for a specialist Sr. Android Engineer to bridge the gap between high-level application logic and low-level hardware performance. Unlike traditional mobile apps, our software runs on headless media players, System-on-Chip (SoC) TVs, and kiosks that must remain performant and stable 24/7. You will be responsible for building the "engine" that powers global digital signage networks, focusing on heavy media playback, IPTV streaming, and remote device orchestration. Core Responsibilities Embedded Solutions: Design and maintain Android services and apps for headless and non-touch environments, ensuring the application boots instantly and recovers automatically from failures. Advanced Media Playback: Optimize video pipelines using ExoPlayer/Media3 to handle 4K content, seamless looping, and multi-zone rendering without dropped frames. IPTV & Live Streaming: Implement and tune HLS, RTSP, and Multicast (UDP) streaming capabilities, focusing on low-latency delivery and robust buffer management. Hardware Interfacing: Work directly with device hardware APIs (serial ports, HDMI-CEC, USB-HID) to control screens, sensors, and external peripherals. Fleet Management: Develop logic for Remote Device Management (RDM), including silent background updates, real-time telemetry, and remote screenshot/logging capabilities. System Stability: Own "Always-On" reliability—managing memory leaks, thermal throttling, and offline-first data persistence (Room/SQLite) to survive network outages. Technical Requirements Expert Kotlin/Java: Deep understanding of the Android SDK, particularly background Services, Broadcast Receivers, and WorkManager. Streaming Mastery: Proven experience with streaming protocols (HLS, DASH, RTSP, Multicast) and hardware-accelerated video decoding (H.264/HEVC). Networking: Strong knowledge of Sockets, MQTT, and WebSockets for real-time device-to-cloud communication. Performance: Experience with profiling tools (Android Profiler, Systrace) to minimize CPU/GPU overhead and ensure 99.9% uptime. Modern Architecture: Professional experience with MVVM, Clean Architecture, and Dagger/Hilt. Preferred Requirements SoC Experience: Experience developing for professional displays (e.g., Sony Pro Bravia, Philips/TPV, or specialized Android Media Players). AOSP/MDM: Knowledge of Android Enterprise, Custom ROMs, or MDM (Mobile Device Management) APIs. Web Technologies: Familiarity with the WebView stack and hardware-accelerated Chromium rendering (common in signage). CI/CD: Experience with automated deployment to physical device labs. Requirements 5+ years of professional software engineering experience, with a strong focus on Android development Expertise in Kotlin and/or Java with deep knowledge of the Android SDK Experience building and maintaining Android background services, including Services, Broadcast Receivers, and WorkManager Strong experience with media playback frameworks such as ExoPlayer or Media3 Hands-on experience with video streaming protocols, including HLS, RTSP, DASH, or Multicast Solid understanding of networking concepts, including sockets, MQTT, and WebSockets Experience working with hardware-accelerated video decoding (e.g., H.264, HEVC) Experience optimizing application performance using tools such as Android Profiler or similar Proven ability to troubleshoot and resolve system-level issues (memory, CPU, stability) Experience designing and building highly reliable, always-on systems This position is open to external candidates in Florida, North Carolina, or Texas and offers the flexibility of remote work.
