iOS Engineer - Objective C/SWIFT

Job Description :

We are looking for a highly skilled iOS Engineer to join our mobile engineering team. 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.
