Role Summary
Mid-to-Senior Mobile Software Engineer (iOS) focused on SDK and platform engineering: building, integrating, and maintaining iOS SDKs, library modules, reference apps, and multiple customer-facing iOS applications. Strong Swift and shipping experience required. Bonus: Kotlin Multiplatform (KMP) or React Native. Hands-on role that values practical engineering and developer experience over deep low-level iOS specialization.
Key Responsibilities
Build and maintain iOS SDK/library modules (XCFrameworks, CocoaPods/SPM), Xcode project setup, versioning, and local/remote publishing
Integrate the SDK into sample, reference, and customer production apps; keep implementations aligned with real-world usage patterns
Build and manage multiple customer iOS applications alongside reference apps—handling app-specific configuration, branding, and release cycles
Apply Clean Architecture, MVVM/Coordinator patterns, UIKit/SwiftUI, Combine/async-await, and dependency injection
Maintain CI/CD pipelines and App Store readiness—signing, provisioning, archive/IPA builds, and policy compliance
Write integration guides, sample code, and API docs; debug issues and feed learnings into SDK improvements
Requirements
5+ years mobile development with strong iOS focus; at least one app shipped on the App Store
Strong Swift (Objective-C familiarity), Xcode, UIKit/SwiftUI, CocoaPods/SPM, and third-party SDK integration
Experience with iOS library/framework modules, dependency management, and artifact publishing (CocoaPods, SPM, XCFrameworks)
Modular app architecture (Clean Architecture, MVVM or Coordinator) and structured, testable codebases
CI/CD for iOS (GitHub Actions, Bitrise, Jenkins, Fastlane); Git, PRs, code review; solid mobile debugging skills
