Key Responsibilities: 
● App Hardening: Implement and maintain RASP (Runtime Application Self-Protection), 
Code Obfuscation (ProGuard/DexGuard), and Root/Jailbreak detection mechanisms. 
● Secure Connectivity: Enforce Certificate Pinning and secure TLS configurations to 
prevent Man-in-the-Middle (MitM) attacks. 
● Data Protection: Ensure no sensitive data (PII, Keys) is leaked in logs, cache, or 
snapshots. Secure usage of Android Keystore and iOS Keychain. 
● Mobile Design Components: Deliver new security design patterns and components 
for Mobile security. Create reusable libraries for biometric login, secure storage, and 
device attestation that feature teams can easily drop into their code. 
● Pentesting: Regularly decompile and attack our own binaries to verify defenses. 

Technical Requirements: 
● Deep knowledge of Android (Kotlin/Java) and iOS (Swift/Obj-C) internals. 
● Experience with mobile security frameworks (OWASP MASVS). 
● Hands-on experience with reverse engineering tools (Frida, Ghidra, MobSF). 
● Understanding of Biometric authentication flows (FaceID/TouchID implementation).
