Responsibilities

Define the overall mobile technical strategy across iOS or Android, including frameworks, tooling, and best practices. As a domain expert to influence system design across mobile and backend teams to ensure scalable and efficient solutions

Architect and implement secure mobile payment solutions using NFC and EMV Co Standards

Help develop and design the long-term mobile platform vision for both iOS and Android. Establish and evolve the core mobile architecture, design patterns, and engineering standards for both platforms. Ensure consistency, performance, and maintainability by setting precedents for dependency injection, module management, and reactive programming across Android (Kotlin) and iOS (Swift)

Lead architectural and code reviews for key features and platform components across multiple mobile teams. Define and enforce a high bar for engineering quality, performance, and reliability through mentorship and process improvements

Use a deep understanding of mobile systems and strategic goals to resolve architectural disagreements and align teams in a single, coherent direction. Act as a neutral technical voice to facilitate decisions on shared libraries, build systems, or cross-platform code

Lead prototyping of complex mobile solutions, such as new SDK integrations, or performance optimizations, validating their technical feasibility and alignment with the overall product roadmap

Act as the mobile expert in product and design discussions, providing a technical perspective on tradeoffs and risks. Influence product teams to prioritize platform health, accessibility (for both iOS and Android), and technical debt reduction alongside new feature work

Guide the technical planning and execution for major mobile-specific initiatives, such as a full app redesign, a modularization effort, or a large-scale performance overhaul. Directly influence the roadmaps of multiple mobile teams to ensure they are building toward a cohesive architectural vision

Establish department-wide mobile testing strategies, including unit, integration, and UI automation tests (like XCUITest for iOS or Espresso for Android). BrowserStack and Appium experience. Drive adoption of advanced performance monitoring tools and testing practices within the CI/CD pipeline

Mentor other senior engineers on mobile architecture, and design. Lead critical, cross-functional mobile projects from a technical perspective, mobilizing engineers from different teams to achieve a common goal

Stay up to date on the latest Android or iOS tooling and SDKs to proactively identify opportunities for process and efficiency improvements. Champion and lead the development of internal libraries and tooling that improves developer productivity across all mobile teams

Architect and enforce best-in-class mobile security practices, such as code obfuscation, certificate pinning, and secure API integration. Collaborate with security and legal teams to ensure the mobile platform adheres to all data privacy and confidentiality standards (e.g., GDPR, CCPA)

Supporting the company’s commitment to risk management and protecting the integrity and confidentiality of systems and data
