Lead Software Engineer (iOS)

As a
Lead Software Engineer - Mobile (iOS)
, you will take ownership of the design, architecture, and delivery of our iOS applications across the Apple ecosystem. You will be responsible not only for building high-performance, secure, and scalable mobile solutions, but also for setting technical direction, driving engineering excellence, and leading the iOS team members.
You will work closely with cross-functional stakeholders (Product, Design, Backend, QA, Security, DevOps) to align technical execution with business goals. In addition to being a hands-on contributor, you will mentor engineers, guide architectural decisions, and ensure the team consistently delivers high-quality, secure, and impactful products.
Key responsibilities
Technical Leadership:
Own the end-to-end iOS architecture, ensuring scalability, maintainability, and long-term evolution of the platform
Define and enforce coding standards, architectural guidelines, and best practices across the iOS team
Drive technical decision-making, including trade-offs between performance, security, and time-to-market
Lead technical planning and estimation, ensuring alignment with product roadmap and delivery timelines
Act as the primary point of contact for all iOS-related technical decisions and escalations
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.
Qualifications
Education:
Bachelor's degree in Computer Science, Engineering, or related field. Master's degree preferred.
Experience:
8+ years

Practical experience with SwiftUI.
Experience with Swift Concurrency, Combine, or Reactive frameworks.
Experience with architectural patterns (e.g., MVVM, VIP, Clean Architecture).
Experience with testing frameworks (e.g., Swift Testing).
Experience with building large-scale, high-performance iOS applications
Experience with CI/CD, unit/UI testing, and performance profiling tools (e.g., Instruments, Xcode profiler).
Proven experience designing and implementing robust networking layers (REST, WebSockets, gRPC, GraphQL, etc.).
Good understanding of security best practices: SSL pinning, certificate management, secure data storage, authentication flows.
Familiarity with background networking, offline support, and data synchronization.
Experience leading or mentoring engineers and driving code quality through reviews and standards
Excellent problem-solving, debugging, and analytical abilities.
Good communication and collaboration skills.
Nice to have:
Strong product sense and customer empathy.
Experience with map-based products and location-driven user experiences.
Good understanding of real-time GPS tracking, location accuracy, update frequency, battery impact, and poor-signal scenarios.
Understanding of subscription and freemium products
Strong understanding of privacy, consent, and location-sharing UX.
Able to challenge unclear requirements and propose better product solutions.
Fluency in English is a plus.
