The ideal candidate has a strong background in native iOS development and is equally comfortable working across Android and Flutter codebases. This role covers the mobile side of a client's test-automation platform - the device agents, the automation libraries injected into the applications under test, and the associated Flutter plugins. Key Responsibilities : - Develop new functionality and fix issues in mobile automation libraries across iOS, Android, and Flutter. - Keep the mobile stack compatible with new iOS, Android, Xcode, and Flutter releases. - Contribute to mobile R&D initiatives such as WebDriverAgent-based automation and SwiftUI/Flutter support. - Troubleshoot customer-escalated mobile issues, including crashes after instrumentation, element identification failures, and replay failures. - Own mobile release logistics: certificates, provisioning profiles, entitlements, keystores, customer-specific builds, IPA/APK re-signing, and artifact publishing. - Maintain internal documentation covering mobile internals, build processes, and signing processes. Required Qualifications & Skills : - Expertise in iOS development with Objective-C (including non-ARC code) and Swift. - Minimum of 5 years of mobile development experience, with a primary focus on iOS. - Deep understanding of UIKit and the Objective-C runtime - swizzling, private APIs, synthesized events, and accessibility. - Strong knowledge of Apple code signing: certificates, provisioning profiles, entitlements, and IPA export/re-signing. - Experience building static/dynamic libraries and XCFrameworks with xcodebuild and shell scripts. - Ability to read, debug, and modify Android (Java/Kotlin, Gradle) and Flutter/Dart code. - Strong debugging skills across device logs, crash reports and symbolication, adb, and logcat. - Experience with mobile networking (TCP/UDP sockets, RPC, WebSockets) and Bash scripting. - Proficient with Git and standard issue-tracking/CI tooling (e.g., Azure DevOps, JIRA). - Excellent written and spoken English. Good to Have: - Knowledge of Android internals: Instrumentation, accessibility services, reflection into hidden APIs, Jetpack Compose. - Experience with APK repackaging: apktool, smali/dex, apksigner, keystores. - Experience developing and publishing Flutter plugins (pub.dev) and CocoaPods podspecs. - Knowledge of XCUITest, WebDriverAgent, or Appium. - Knowledge of WebKit/WKWebView, Safari web extensions, and JavaScript. - Basic understanding of .NET/C# and NuGet packaging. - Genuine enthusiasm for learning new technologies.
