Experienced iOS/Android Developer Needed for Modification of Delivery Service App (No Source Code)
Job Description:
We are looking for a skilled mobile developer (iOS and/or Android) to modify an existing delivery service application without access to its source code. The project involves working directly with the app binary to implement custom features and bypass security mechanisms.
Key Responsibilities:
• Modify and patch the app without source code access (app reverse engineering, hooking, patching)
• Implement anti-fraud bypass techniques and security workarounds
• GPS location spoofing and simulation of courier behavior (GPS jumps, route switching)
• Enhance multimedia functionality (e.g., replace forced camera usage with gallery selection)
• Automate key user actions such as auto-accepting and completing orders
• Ensure compatibility and stability across different devices and OS versions
Required Skills:
• Strong experience in iOS (Objective-C/Swift) and Android (Java/Kotlin) development
• Expertise in reverse engineering tools and techniques (Frida, IDA Pro, Hopper, Theos, etc.)
• Familiarity with jailbreak-less injection methods (e.g., TrollStore, dylib injection)
• Experience with root/Magisk and system-level hooking on Android
• Knowledge of anti-fraud systems and methods to bypass them (SafetyNet, custom protections)
• Ability to develop automation scripts (Python, AutoJS, Uiautomator2)
• Experience with app instrumentation, logging, and debugging without source code
• Previous work on closed/internal test projects or delivery/e-commerce apps is a plus
Additional Info:
• This is a closed project intended for internal testing only, not for public release
• Budget is negotiable depending on developer skills and experience
• Long-term collaboration preferred, starting with a trial phase
