[Hiring] Senior Android Engineer @SPECTRIO LLC

Role Description

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.

Qualifications

• 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.

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.
