Android System Engineer (Camera Injection)

Requirements

• Experience with Google's AOSP and custom ROM development
• Strong knowledge of Android Camera HAL and frameworks like CameraX and Camera2
• Experience in modifying the Android HAL and kernel-level programming.
• Experience working with SE Linux and secure boot.
• Experience in working with USB interfaces on Android and understanding how to bridge data from external sources to Android's camera system.
• Expertise with device drivers, particularly related to cameras on Android.
• Knowledge of custom kernel compilation for Android.
• Knowledge of Android 10 system internals.

Nice to Have

• Prior experience developing virtual camera drivers or working with media injection into Android camera systems.
• Experience with rooted devices, custom recovery (TWRP), and debugging tools for Android hardware.
• Familiarity with network streams (e.g., RTSP) and video streaming protocols, and how to handle them on Android to integrate external media sources into Android devices.
• Experience with tools like gstreamer or FFmpeg for handling media streams.

What You'll Be Doing

• Creating an app or settings interface within the ROM that allows users to choose what type of media to inject into the camera: a static photo, a video file, or a network video stream (e.g., an RTSP stream)
• Ensuring the injected media replaces the live camera feed and is displayed in the preview of the default Camera app
• Making sure the injected media is recognized by any apps that use CameraX or Camera2 API, as if it were coming from the phone's physical camera
• Ensuring capturing the injected media using the camera's shutter button or automatic capture works the same way it would for a live camera feed
• Supporting testing and debugging to ensure proper functionality of camera injection
• Performing R&D on new methods of camera injection and techniques for detecting them across Android devices
• Becoming the foundational member of a new team aimed at focusing on developing secure Biometric Identification solutions
