Our client is a mobile identity and security company whose platform protects high-assurance apps from attack while they run — on devices the company doesnt control. Theyre hiring a hands-on Product Security Engineer to help build out their mobile application security (RASP) platform. This is a genuine builder role, not a policy or governance one.

What youll be building: Youll ship the in-house shields that defeat rooting/jailbreaking, hooking and instrumentation, emulators, tampering and repackaging, malware, and network interception (MITM, SSL-pinning bypass, malicious VPN/proxy) — built on top of a licensed RASP core.
Youll own the applied cryptography behind secure local storage and app/device attestation,



plus the iOS symbol-obfuscation and binary-hardening tooling that closes native reverse-engineering gaps across Swift, C, C++ and Objective-C.

- Mobile SDK development in iOS (Swift/Obj-C) and/or Android (Kotlin/Java), ideally security- or SDK-focused
- Experience integrating and extending third-party SDKs via callback/
