About the role

Our Technology team isn’t just one of the best in the industry, it’s one of the best in the world. And we’re proud of it. It’s our driving force; our engine. From building a new banking backend to creating an award-winning app, there’s nothing (and we mean nothing) our tech team can’t do.

We're looking for an Android Engineer with deep expertise in low-level Android (native libraries, kernel-level work) and Application Security (SELinux, Frida). You'll tackle advanced camera injection challenges - ensuring injected media mimics real hardware input and appears seamlessly across the native Camera app and any third-party apps using CameraX or Camera2 APIs.

If this is ‘so you’, you know where to find us.

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 recognised 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

What you'll need

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 of how to bridge data from external sources (e.g., OBS) 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
