• Design, build, and maintain high-performance, scalable Android applications using Kotlin (primary) and Java (when needed). • Collaborate closely with product managers, designers, QA engineers, and backend teams to define requirements and deliver polished features. • Translate business and user requirements into clean, maintainable, and testable code following modern Android architecture best practices (MVVM, MVI, Clean Architecture). • Implement pixel-perfect UI/UX following Material Design 3 guidelines and ensuring excellent performance across a wide range of Android devices and OS versions. • Integrate REST/GraphQL APIs, handle offline support, data persistence (Room,DataStore), secure authentication, push notifications, and analytics. • Write robust unit, integration, and UI tests (JUnit, Espresso, Robolectric, MockK). • Participate in code reviews, architectural discussions, and continuous improvement of the mobile codebase. • Localize app content and UI strings for English and Spanish-speaking users; adapt features to regional preferences and compliance requirements. • Communicate effectively in both English and Spanish during meetings, documentation, user support tickets, and stakeholder updates. • Debug and resolve production issues quickly while maintaining high code quality and app stability. • Stay current with Android ecosystem changes (new Jetpack libraries, Kotlin Multiplatform Mobile when relevant, Google Play policies, etc.)

• Develop new Android applications and evolve existing architectures using Kotlin and Java. • Create user interfaces and flows, integrating services, APIs, and Android system components. • Propose architectural solutions, design patterns, and best practices to ensure app performance, security, and quality. Work on building new modules and features from planning through implementation and delivery. • Perform evolutionary and corrective maintenance when necessary, ensuring stability and compatibility. • Investigate complex issues, performing advanced debugging and log analysis in logcat, including application and framework layers (SELinux, permissions, etc.). • Adapt and optimize system apps for new Android versions, considering API changes and OS behavior. • Actively participate in code reviews, contributing to internal standards and sharing knowledge with the team. • Collaborate on an international project, using English for reading, writing, and conversation.

• Architectural Leadership: Lead the design and implementation of complex, scalable mobile architectures. You’ll ensure our codebase remains modular, testable, and maintainable as we scale. • Product Strategy: Partner deeply with Product, Design, and Sports Science to turn ambiguous requirements into concrete technical roadmaps. You’ll build high-fidelity prototypes to de-risk new product directions. • Operational Excellence: Own the end-to-end lifecycle of our apps. This includes obsessing over performance (app startup, frame rates, battery usage) and optimizing our CI/CD pipelines to ensure we ship high-quality code daily. • Data Visualization: Design and build sophisticated tools that transform complex athlete data into intuitive, actionable insights. • Mentorship & Culture: Raise the collective bar of the engineering team. You will conduct rigorous code reviews, lead technical discussions, and mentor mid-level and junior developers. • Innovation: Actively research and pilot new technologies (e.g., Compose, KMP, or New Architecture components) to keep our stack at the cutting edge.

• Conduct in-depth analysis of Android applications and SDKs to understand their codebase, architecture, functionality and to identify potential risks • Employ advanced reverse engineering techniques to extract information from various codebases, including decompilation, disassembly, and debugging • Identify user and device risk, data leakage, and malicious code execution within Android apps and SDKs • Gather, analyze and report threat intelligence related to Android malware, exploits, and emerging security trends • Collaborate with security researchers, developers, and other stakeholders to share findings, provide recommendations, and contribute to the development of secure applications and ecosystem.
