Role Overview

We are looking for an expert Android developer to lead the "hardening" phase of our next-generation Time Clock application (Humanity Time Clock V3). Unlike standard Play Store apps, our software runs on dedicated, proprietary Android hardware.

The ideal candidate has deep experience transforming standard Android apps into robust, bulletproof "Kiosk" systems. You will be responsible for locking down the OS, managing system-level peripherals, and ensuring the device can run 24/7/365 without user intervention.

As a Senior Android System Developer, you will:  

• Kiosk Implementation: Implement and refine Android Lock Task Mode (Screen Pinning) to prevent users from exiting the application or accessing the OS settings.
• System Hardening: Disable or hide system UI elements (Status Bar, Navigation Bar, Notification Shade) programmatically to ensure a fully immersive experience.
• Watchdog & Resilience: Implement self-healing mechanisms, such as WorkManager tasks and AlarmManager watchdogs, to automatically restart the app or services in case of crashes or ANRs.
• Boot & Update Management: Optimize the BootReceiver logic for instant startup and manage robust OTA (Over-the-Air) update flows.
• Security: Secure local data using EncryptedSharedPreferences and Android Keystore. Hardening communication channels (MQTT/TLS) and preventing ADB abuse in production.
• Peripheral Integration: Optimization of hardware drivers/SDKs (Biometrics, Card Readers) to prevent resource leaks and ensure stability over long uptimes.
• Logs & Diagnostics: Implement robust audit logging (local & remote) to trace issues on devices deployed in the field.

• 5+ Years Android Development (Kotlin required).
• Deep understanding of the Android Lifecycle and Process Management (how to keep an app alive indefinitely).
• Experience with COSU (Corporate-Owned, Single-Use) or Dedicated Device configurations.
• Experience processing hardware events (USBs, Serial Ports) and managing background services.
• Strong knowledge of Device Owner / Profile Owner APIs (Android Enterprise).

Nice to Have

• Familiarity with MQTT protocols and real-time communication resilience.
• Experience with AOSP (Android Open-Source Project) or modifications to the Android Firmware/ROM.
• Experience creating System/Privileged Apps (signed with platform keys).
• Experience with MDM (Mobile Device Management) solutions (SOTI, AirWatch, or custom implementations).
• Background in identifying memory leaks (LeakCanary) and optimizing for low-spec hardware.

Physical Requirements:

• Prolonged periods sitting at a desk and working on a computer.
• Must be able to lift up to 15 pounds at times.
• This role requires 0% travel time.

• Competitive salary
• 20 Days of PTO (Paid Time Off) and 13 days of companywide holidays 
• 8 hours to volunteer and impact the community 
• Comprehensive benefits (Health/Dental/Vision/ 401K) 
• Employee Choice Pre-Tax Benefit
• Remote work option available
