Responsibilities

• Guide Neighborhoods mobile technical direction across Cash App and Square.
• Lead strategic, cross-organizational mobile workstreams within a company-level initiative to redefine local commerce and connect the Square and Cash App ecosystems.
• Drive cross-organizational architecture and execution with teams across Square and Cash App to deliver seamless integration of Neighborhoods loyalty, marketing, and ordering features in Cash App running on Square’s platform.
• Guide the architecture of mobile systems that connect customer discovery in Cash App with seller ordering and fulfillment workflows in Square Point of Sale.
• Stay hands-on in iOS development using SwiftUI, Workflow, and related technologies across the Square Point of Sale and Cash App codebases, making architectural tradeoffs that keep mobile experiences reliable, scalable, and polished.
• Partner with backend, web, and Android engineers to ship features with a focus on quality and craft, while mentoring engineers and raising technical standards across the team and partner teams.
• Work cross-functionally with product managers, designers, and engineering leaders to define product scope, sequence ambiguous cross-team work, and make clear technical and product tradeoffs.
• Use AI tools as a native part of feature development: exploring unfamiliar codebases, prototyping product ideas, accelerating implementation, generating tests, improving observability, and tightening documentation.
• Identify, teach, and scale practical AI-assisted workflows for product engineering, especially in cross-codebase feature work, migration, debugging, QA, experimentation, and rapid iteration.
• Apply strong judgment around AI-generated work: verify behavior, protect customer trust, preserve maintainability, and use AI to raise the team’s technical bar.
• Model how a staff engineer uses AI to multiply impact without losing product taste, architectural ownership, or accountability for the systems we ship.
