• Architect, design, and develop scalable native iOS applications using Swift, SwiftUI, and UIKit.
• Write clean, maintainable, testable, and high-performance code.
• Design modular and testable application architectures using MVVM, MVC, Clean Architecture, or similar patterns.
• Apply advanced Swift concepts including concurrency, async/await, protocols, generics, and memory management.
• Work with Apple APIs and frameworks such as LocalAuthentication, AuthenticationServices, WebKit, CommonCrypto/CryptoKit, and related technologies.
• Identify and resolve application performance and memory issues using Instruments and profiling tools.
• Participate in architecture discussions, technical design reviews, and code reviews.
• Support the complete iOS application lifecycle, including build, testing, signing, provisioning, deployment, and production support.
• Work with CI/CD pipelines and automated mobile application delivery processes.
• Mentor developers and promote strong iOS engineering and coding practices.
• Effectively use AI-assisted development tools while maintaining strong foundational engineering practices.

Required Qualifications

• Strong professional experience developing native iOS applications.
• Advanced hands-on expertise with Swift.
• Strong experience with both SwiftUI and UIKit.
• Deep understanding of Swift concurrency, async/await, GCD, protocols, and generics.
• Strong understanding of memory management, data structures, algorithms, and concurrency.
• Experience designing applications using MVVM, MVC, Clean Architecture, or similar architectural patterns.
• Experience building and shipping complex production iOS applications.
• Strong knowledge of the broader Apple SDK and iOS ecosystem.
• Experience with Xcode, Instruments, performance profiling, debugging, and crash analysis.
• Experience with CI/CD pipelines for iOS applications.
• Understanding of code signing, certificates, provisioning profiles, TestFlight, and application deployment.
• Experience writing unit-testable code and working with iOS testing frameworks.
• Strong written and verbal communication skills.
• Bachelor's degree in Computer Science or a related discipline, or equivalent practical experience.
• Ability to work onsite in Alpharetta, GA at least 3 days per week.

Preferred Qualifications

• Experience with LocalAuthentication, AuthenticationServices, WebKit, CommonCrypto, or CryptoKit.
• Experience developing or integrating APIs.
• Familiarity with Android/mobile application development.
• Strong understanding of mobile user experience principles.
• Experience mentoring or providing technical guidance to other developers.
• Experience using AI-assisted software development tools.

Interview Focus

Candidates should be comfortable discussing real-world examples of their own iOS development work, particularly around:

• Advanced Swift language concepts, including concurrency, generics, and protocol design.
• Apple APIs and frameworks, including UIKit, SwiftUI, AuthenticationServices, WebKit, and related frameworks.
• iOS ecosystem and engineering practices, including Xcode, CI/CD, performance tuning, app signing, crash analysis, and architectural decisions.

We are looking for engineers who demonstrate strong technical depth, architectural thinking, clear communication, and genuine craftsmanship in native iOS development.
