• Evolve how Cash App's Android engineering org uses AI
• Proactively identify where AI creates real leverage in platform and product engineering workflows, and act on it
• Introduce and evaluate emerging AI development tools (Claude Code, GPT/Codex, Goose, and what comes next), forming a clear point of view on adoption
• Build AI-powered capabilities into the platform itself where they create durable value for product teams
• Operate beyond your immediate team. Identify cross-cutting technical problems across Cash App's Android org and mobilize the resources to address them
• Surface unknown risks and systemic issues before they become customer problems or engineering crises
• Lead architecture and design reviews across team boundaries - help set standards that scale
• Mentor and grow engineers at all levels, raising the technical ceiling of the Android community at Cash App
• Partner with engineers, product managers, and designers across Cash App to align platform investments with what teams actually need
• Represent Android platform needs in cross-functional, cross-org, and Block-wide technical discussions

• Strong systems thinking - You identify non-obvious problems and design solutions that are simple enough to be right
• Exceptional communication - crisp design docs, productive design reviews, and the ability to build alignment across senior engineers and non-engineers alike
• Deep Android expertise - Kotlin, Jetpack Compose, modern architecture patterns, build systems, performance profiling, and testing at scale
• Experience building developer platforms, shared libraries, or internal tooling used across large engineering organizations
• Experience with Kotlin Multiplatform
• Background in fintech, financial services, or other high-trust regulated environments
