Product Security Engineer — Mobile RASPThis 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 doesn't control. They're 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. You'll write production code across mobile and backend, working at high velocity with AI as your primary development accelerator.What you'll be building:You'll 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. You'll 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 you'll also build and operate the platform's 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 you're building the product, you'll 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 we're looking for:Strong, current, hands-on software engineering — you code daily and ship to productionMobile SDK development in iOS (Swift/Obj-C) and/or Android (Kotlin/Java), ideally security- or SDK-focusedExperience integrating and extending third-party SDKs via callback/event APIsCode-hardening experience — obfuscation and binary hardening across native mobile toolchainsApplie
