• Take ownership & anticipating significant technical projects, managing dependencies both internally and externally, to realize the engineering and product visions.
• Drive the user experience forward by partnering with Product Managers & Designers, implementing intuitive UI animations, transitions, and accessibility features, while ensuring adherence to our Design System.
• Architect robust and efficient code patterns, by leveraging the latest iOS & Android technologies, while maintaining a commitment to the app architecture principles, like modularity and dependency injection.
• Advocate for efficient testing methodologies, from unit and UI tests to cutting-edge end-to-end practices, ensuring the highest quality and reliability of the features developed.
• Monitor app performance meticulously, utilizing tools like Datadog and Crashlytics to track UI and core functionality, and implement strategies to prevent regressions.
• Act as an internal spokesperson for the mobile engineering stack, advocating for technical initiatives internally, and representing Back Market at external tech events, conferences, and meetups, while also contributing to the broader tech community through articles and continuous learning.
