Senior Android Engineer; Digital Signage & Media Platforms

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.

• 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 Exo Player/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.

• Expert Kotlin/Java:
  Deep understanding of the Android SDK, particularly background Services, Broadcast Receivers, and Work Manager.
• 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 Web Sockets 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.

• 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 Web View stack and hardware-accelerated Chromium rendering (common in signage).
• CI/CD:
  Experience with automated deployment to physical device labs.

• 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 Work Manager.
• Strong experience with media playback frameworks such as Exo Player or Media
  3.
• Hands‑on experience with video streaming protocols, including HLS, RTSP, DASH, or Multicast.
• Solid understanding of networking concepts, including sockets, MQTT, and Web Sockets.
• 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.

• Work From Home – Remote Culture.
• Vacation/Personal Time:
  Prorated PTO that accrues per pay period after 30 days of employment.
  • Under 3 years of service: 15 days per year.
  • 3–5 years of service: 17 days per year.
  • 5+ years of service: 20 days per year.
• Paid Sick Leave:
  All employees accrue up to 40 hours per year.
• Company Paid Holidays: 10 observed holidays per year.
• Medical Insurance:
  Three plan options (Low HSA, Mid, High).
• Dental Insurance:
  High and Low PPO plan options.
• Vision Insurance.
• Basic Life Insurance: $50,000 policy, 100% employer-paid.
• Short-Term Disability: 100% employer-paid; covers 60% of weekly salary for up to 26 weeks.
• Voluntary Benefits:
  Optional purchase of Voluntary Life, AD&D, Long-Term Disability, Accident, Critical Illness, Hospital Indemnity.
