• Experience modernizing legacy codebases and incrementally improving architecture, testability and module boundaries.
• Strong grasp of mobile architecture patterns (e.g., MVVM, Coordinators), dependency injection and module design.
• Experience integrating with networked backends (REST), offline caching/sync, background tasks and secure local storage.
• Proficiency with testing (XCTest, XCUITest) and a pragmatic approach to test coverage and automation.
• Hands-on with tooling and CI/CD for iOS (e.g., Fastlane, Xcode Cloud, Bitrise or similar) and Swift Package Manager.
• Clear, empathetic communication skills; ability to influence, align stakeholders and drive clarity across teams.
• A thoughtful sense of ownership and autonomy; comfortable making well‑reasoned trade‑offs and following through to great outcomes.

Nice to have:

• Background in camera, image capture or image processing or exposure to Core ML/computer vision.
• Familiarity with Swift frameworks and patterns such as SwiftUI, async/await and Combine.
• Familiarity with continuous release practices (feature flags, staged rollouts, phased releases).
