You will be a hands- on contributor, writing code, reviewing code, and mentoring other engineers.

Key responsibilities

Hands-on Development:

• Design, build and maintain the end-to-end implementations that protect user privacy and user’s daily activities on digital platforms across the entire Apple ecosystem.
• Collaborate with cross-functional teams (Product, QA, Backend, SOC, etc.) to deliver the secure, high-performance implementations aligned with the team’s overall strategy.
• Conduct code reviews to ensure code quality and adherence to best practices.

Performance Optimization:

• Identify and address performance bottlenecks in the iOS applications.
• Conduct research into Apple’s privacy frameworks to ensure our solution is both effective and fully policy compliant.

Additional Responsibilities:

• Build secure mobile solutions with strong understanding of encryption, secure storage, and anti-tampering techniques.
• Apply modern iOS architecture patterns (Clean Architecture / modularization) to build scalable and maintainable protection modules.
• Ensure thread safety and performance using Swift Concurrency (actors, Sendable, structured concurrency).
• Integrate with backend-driven threat intelligence systems and continuously update on-device protection logic.
• Implement observability, logging, and monitoring systems to track app performance and security effectiveness.
• Contribute to automated testing strategies, including edge-case and security-related scenarios.
• Mentor and coach other junior engineers, helping them grow their iOS skills.
