  • Build reusable SwiftUI components aligned with the application design system
  • Write and maintain unit and UI tests
  • Support DEV, UAT, and PROD configurations and environment-specific resources
  • Contribute to build, release, code signing, provisioning, and App Store distribution
  • Participate in code reviews, technical design discussions, and architecture improvements
  • Troubleshoot, debug, and optimize application performance
  • University degree in Computer Science, Engineering, or a related field
  • Minimum 5 years of professional experience in Swift and native iOS development
  • Strong hands-on experience building production applications with SwiftUI
  • Solid understanding of Swift Concurrency, including async/await, actors, and actor isolation
  • Experience with Swift Package Manager, modular iOS applications, and reusable Swift packages
  • Experience integrating backend APIs, authentication or identity services, and third-party SDKs
  • Knowledge of secure token storage using the iOS Keychain
  • Strong experience with Xcode, Instruments, debugging, and performance-analysis tools
  • Experience writing unit and UI tests using XCTest and XCUITest
  • Experience with Xcode build configurations, code signing, provisioning, and multiple application environments
  • Familiarity with Git-based collaborative development workflows and code reviews
  • Experience working within an Agile delivery environment
  • Strong communication, collaboration, and ownership skills

Nice to Have• Experience with SignalR or another real-time communication technology

  • Experience with Jumio or another KYC/identity-verification SDK
  • Experience with NFC, camera, Face ID, and secure mobile onboarding journeys
