Join Apple's Messages Services and Security team as a Senior Engineer based in Washington, United States, responsible for designing and ensuring the robustness of Messages' core delivery and security features. You will design end-to-end protocols for new Messages features, develop maintainable Swift frameworks such as BlastDoor to improve reliability and security, and build infrastructure for safe data handling to prevent zero-click attacks. Collaborate with cross-functional teams including Telephony, IdentityServices, iCloud, Wallet, and media codec teams to enable experiences like iMessage, Messages via Satellite, Emergency SOS via Satellite, Messages for Business, SMS Relay, and RCS. You will contribute to security initiatives that isolate and sandbox untrusted data as it arrives through various Messages services, and you will create testable code to ensure quality over time. Requirements include 6+ years of industry experience, strong object-oriented development skills, proficiency in Swift and/or Objective-C, and the ability to reason about the security and robustness of applications.
