Role Summary

We are seeking a Senior iOS Mobile Developer to join our Specialized App team and help deliver premium mobile experiences that support Specialized’s rider-focused initiatives. In this role, you will design and build best‑in‑class iOS applications using Swift, applying event‑driven programming patterns to create responsive, efficient, and scalable solutions. You will also collaborate in an architecture that leverages Kotlin Multiplatform (KMP) as a shared business logic layer between Android and iOS, ensuring consistency and efficiency across platforms. Working closely with product managers, designers, Android engineers, and backend teams, you will help build engaging mobile experiences that elevate the Specialized rider ecosystem.

How You'll Make a Difference

• Develop, enhance, and maintain iOS applications using Swift, SwiftUI, Combine, and modern event‑driven architectures
• Collaborate on a Kotlin Multiplatform (KMP) setup, integrating a shared business logic layer used across Android and iOS while ensuring a first‑class native iOS experience
• Design and implement efficient caching strategies in both native and shared layers to improve app performance, responsiveness, and offline reliability
• Work closely with cross‑functional teams—including product managers, designers, Android engineers, and backend developers—to define and deliver seamless, cross‑platform user experiences
• Lead technical discussions, mentor junior developers, and champion best practices in code quality, mobile architecture, testing, and performance optimization across iOS and shared KMP components
• Analyze complex technical problems, propose scalable solutions, break down features into manageable tasks, and lead implementation efforts across platform boundaries
• Contribute to the long‑term architectural vision for Specialized’s mobile platforms, helping standardize development approaches, shared business logic, and tooling using KMP
• Continuously evaluate new technologies, frameworks, and patterns to improve app reliability, maintainability, and overall rider experience

• Deep expertise in Swift and modern iOS development, with strong handson experience using SwiftUI, Combine, and reactive/eventdriven patterns
• Experience with Kotlin and Kotlin Multiplatform (KMP) for shared domain and business logic across Android and iOS is highly desirable
• Strong understanding of event‑driven programming principles and the ability to design reactive, scalable, and testable mobile systems across native and shared layers
• Solid experience designing and implementing caching strategies and working with local persistence solutions (e.g., Core Data) to support performance and offline use
• Familiarity with common mobile architectures such as MVVM, MVC, MVP, and Clean Architecture, including applying these patterns in cross‑platform contexts
• Proven ability to break down complex problems, evaluate trade‑offs, and deliver elegant, maintainable solutions
• Strong communication and collaboration skills, comfortable working with both technical and nontechnical stakeholders in crossplatform teams
• Experience mentoring other engineers and helping set technical direction and best practices within a mobile development team
