• Foster continuous improvement in engineering practices, tooling, and workflows
• Collaborate closely with product, design, and delivery teams to translate requirements into technical solutions
• Champion code reuse and shared component strategies across mobile and web while knowing when native implementations are the right choice
• Participate actively in Agile ceremonies (sprint planning, standups, retrospectives, backlog refinement) to ensure overall engineering progress aligns with roadmaps and timelines
• Maintain awareness of engineering health across all technology layers of the product — not just mobile
• Identify cross-layer risks, dependencies, and blockers; escalate proactively
• Know when to engage subject matter experts for other technology layers (services, web, AEM) and facilitate collaboration to resolve cross-cutting concerns
• Ensure that mobile implementations integrate cleanly with native modules, APIs, backend services, and content platforms
• Stay current with React, React Native, iOS, Android, JavaScript/TypeScript, and mobile ecosystem trends
• Evaluate emerging frameworks and methodologies (Kotlin Multiplatform, Flutter, Jetpack Compose, SwiftUI evolution, new React Native architecture)
• Drive adoption of modern cross-platform and native mobile technologies and development patterns

• Solid experience working with offshore teams and driving work through closure across distributed teams
• Scope control and management
• Experience building, leading, or scaling multi-platform mobile development teams
• Ability to influence technical direction across multiple teams or product lines
