Senior Mobile Engineer

ESSENTIAL DUTIES AND RESPONSIBILITIES

- Design, develop and maintain features in the mobile application (Angular + Ionic + Capacitor) for both iOS and Android from a single TypeScript codebase.

- Implement and consume REST APIs exposed by the Java/Spring services layer, including authentication, account and billing, payments, wallet, paperless billing and notification preferences.

- Integrate native device capabilities through Capacitor and Cordova plugins, including biometric authentication, secure storage, push/status bar/splash, in-app browser and deep links.

- Work with AWS Cognito / Amplify authentication flows, including registration, password reset, multi-factor authentication and token refresh.

- Build and release the applications through the teams Azure DevOps pipelines (Gradle/Android App Bundle for Android, Xcode for iOS), and support App Store and Google Play submission, signing, provisioning and store review.

- Write and maintain unit tests (Karma/Jasmine), meet linting and formatting standards (ESLint/Prettier) and participate in peer code review.

- Diagnose and fix production defects across the mobile stack, including device-specific and platform-version-specific issues, using logs and reproduction on physical devices and simulators.

- Ensure delivered work meets accessibility, responsiveness, performance and secure-coding expectations appropriate to a public-facing utility payment application.

- Participate in Agile ceremonies (sprint planning, daily stand-ups, backlog grooming, reviews and retrospectives) and provide realistic estimates and clear status.

- Contribute to technical documentation, release notes and knowledge transfer, and mentor less experienced engineers on the team.

EDUCATION & EXPERIENCE

- Bachelor’s degree in Computer Science, Engineering or a related discipline, or equivalent practical experience.

- 6 to 10 years of professional software engineering experience, including at least 4 years building and shipping production mobile applications to the Apple App Store and Google Play.

- Strong, demonstrable experience with modern Angular (Angular 16 or later; the current codebase is on Angular 20), including TypeScript, RxJS, reactive forms, standalone components and component-based architecture. This is a firm requirement; the mobile application is an Angular application.

- Hands-on experience with Ionic and Capacitor (or Cordova) hybrid mobile development, including native plugin integration and platform build tooling.

- Proficiency with HTML5, SCSS/CSS, Bootstrap and responsive, mobile-first UI implementation.

- Practical experience consuming and debugging REST/JSON APIs, and a working understanding of token-based authentication (OAuth2/OIDC/JWT).

- Experience with the native build toolchains (Android Studio/Gradle and Xcode), including app signing, provisioning profiles and store release mechanics.

- Experience with Git-based branching workflows in Bitbucket, CI/CD pipelines in Azure DevOps, and unit testing frameworks such as Jasmine/Karma.

- Familiarity with Agile delivery and tooling: Jira and Confluence for tracking and documentation, Azure DevOps for build and release.

- Excellent written and verbal English communication, and the ability to work independently with stakeholders in a different time zone.

Nice to have

- Experience in utilities, billing, payments or other regulated/high-volume consumer domains.

- Familiarity with AWS Cognito and the AWS Amplify libraries.

- Exposure to a Java/Spring backend sufficient to trace an issue across the API boundary.

- Experience integrating third-party payment or billing vendor SDKs, hosted payment pages or iframes.

- Working knowledge of accessibility standards (WCAG 2.1 AA) and mobile application security practices (OWASP MASVS or similar).

- Experience with push notifications, offline behavior, or mobile analytics/crash reporting tooling.

- Experience with Azure DevOps release pipelines for mobile artifacts (App Store Connect / Google Play publishing).

- Prior experience taking over and stabilizing an existing codebase from an outgoing team.
