• Build and operate mobile CI/CD and release management (e.g. Azure DevOps GitHub Actions fastlane): automated builds code signing and store submission workflows through App Store Connect and Google Play Console with staged rollouts and release-health monitoring.
• Implement automated testing across the mobile stack (e.g. XCTest Espresso Detox Appium Maestro) with quality gates; monitor crash and performance data (e.g. Firebase Crashlytics Sentry) to drive root cause resolution.

Security & Compliance

• Engineer the application secure-by-design aligned with PCI DSS and OWASP MASVS/MASTG: secure storage (Keychain/Keystore) certificate pinning secure token and session handling and least-privilege API access.
• Partner with InfraSec on mobile threat modeling logging monitoring and audit readiness; operate all production releases under formal change management with audit-ready change records.

• Proven ability to translate business and product requirements into shipped mobile capabilities with measurable outcomes and to explain complex concepts to technical and non-technical stakeholders.
• Expertise with mobile platforms: production iOS and Android development native toolchains (Swift/SwiftUI Kotlin/Jetpack Compose) and/or cross-platform frameworks (e.g. React Native Flutter Ionic/Capacitor).
• Mobile testing: automated unit UI and end-to-end testing (e.g. XCTest Espresso Detox Appium Maestro) with quality gates.
• Secure mobile engineering: OWASP MASVS/MASTG secure storage (Keychain/Keystore) certificate pinning and secure token and session handling.
• Release engineering: App Store Connect and Google Play Console submission and review workflows code signing staged rollouts and release management tooling (e.g. fastlane).
• Expertise in CI/CD and tooling: pipeline engineering with Azure DevOps and/or GitHub Actions; development in VS Code or platform IDEs; strong Git fluency.
• Experience with API integration: RESTful services real-time patterns (e.g. WebSockets) efficient client-side caching push notifications (APNs/FCM) and offline-first data synchronization.
• Observability: crash and performance monitoring (e.g. Firebase Crashlytics Sentry) and release-health analysis.
• Strong TypeScript/JavaScript and computer science fundamentals (data structures algorithms design patterns) applied to production codebases.
• Track record of technical leadership: mentoring code and design review or engineering standards ownership.

Take Your Career To The Next Level!
