Product Security Engineer — Mobile RASP This is a Fully Remote role, but the individual needs to be based in Spain. 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. Youll write production code across mobile and backend, working at high velocity with AI as your primary development accelerator. 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. The product spans both sides of the wire, so youll also build and operate the platforms Python (Flask) backend — the APIs and services that ingest threat telemetry, drive the operator console, manage configuration and policy, and forward events to SIEM. Because youre building the product, youll also run hands-on competitive evaluations (against the likes of Promon, Appdome, Guardsquare, Zimperium and Build38) and support the Sales & Solutioning team as a technical pre-sales engineer when needed. What were looking for: * Strong, current, hands-on software engineering — you code daily and ship to production * 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/event APIs * Code-hardening experience — obfuscation and binary hardening across native mobile toolcha
