Your responsibilities will include:

• Design, develop, and maintain our runtime security protection framework for Apple platforms (iOS, macOS, visionOS).
• Research and implement advanced detection and protection techniques, including jailbreak detection, runtime code injection detection, debugger detection, and anti-tampering mechanisms.
• Reverse-engineer OS internals and third-party tools to stay ahead of emerging threats.
• Collaborate closely with teammates across security, mobile development, and platform teams to continuously evolve our protection framework.
• Analyze and adapt the framework to changes in the Apple ecosystem (e.g., new iOS/macOS versions, hardware changes, security mitigations).

Must-have skills and experience:

• Strong C/C++ development skills, with hands-on experience writing low-level code for Apple platforms.
• Experience with Objective-C and familiarity with Apple runtime and dynamic linking mechanisms.
• Solid understanding of macOS and iOS internals (e.g., Mach-O format, dyld, syscalls).
• Experience with reverse engineering tools and techniques (e.g., IDA, Hopper, Ghidra, Frida, LLDB).
• Familiarity with Git and macOS development environments.
• Proven ability to write clean, secure, and maintainable low-level code.

Bonus points for experience with:

• Swift and SwiftUI knowledge (especially related to app behavior and lifecycle).
• Experience with kernel-level security features on Apple platforms (e.g., PAC, sandboxing).
• Familiarity with code obfuscation, anti-debugging techniques, and runtime binary instrumentation.
• Prior work with jailbreak detection or security techniques on iOS.

You’ll thrive in this role if you:

• Are passionate about low-level development and system internals
• Enjoy digging deep into technical challenges and learning how things really work
• Have a strong interest in security or curiosity about how to break and protect apps
• Are comfortable working independently as well as part of a collaborative team

Education:

• Master's degree in Computer Science, Mathematics, or Security—or equivalent experience through work or personal projects
