Staff Product Mobile Engineer, Business Money

About the Role

As a Staff Product Mobile Engineer, you will play a key role in architecting and building user-facing mobile experiences that evolve Gusto’s personal finance platform. Operating across native iOS and Android environments, you will leverage modern declarative frameworks (SwiftUI and Jetpack Compose), a shared GraphQL API layer, and AI-native workflows to deliver seamless end-to-end features. Your work will focus on improving financial tools for everyday employees, helping them reduce financial stress, build healthy money habits, and gain greater control over their paychecks.

Responsibilities

• Architect, build, and deploy native mobile features end-to-end across iOS (SwiftUI) and Android (Jetpack Compose) using a shared GraphQL schema
• Help drive the product development process from concept to launch, ensuring high standards of technical rigor, system performance, and mobile security in a regulated banking domain
• Adopt and maximize the latest best practices for using AI technologies (e.g. Claude) to accelerate cross-platform feature translation, raise code quality, and optimize team velocity
• Collaborate on complex and ambiguous mobile architecture problems in close partnership with Engineering, Product Management, Design, and external banking partners
• Work cross-functionally to build and maintain mobile infrastructure, testing automation, and release pipelines to support dual-platform scaling
• Mentor team members, guide mobile architectural standards, and engage in opposite-platform code reviews to ensure idiomatic code quality across both stacks

Requirements

• 8+ years of professional mobile software development experience with deep expertise in at least one primary native stack (Swift/iOS or Kotlin/Android)
• Willingness and desire to flex across both mobile platforms (iOS and Android), building natively using SwiftUI and Jetpack Compose backed by shared API contracts and AI translation workflows
• Deep understanding of modern declarative UI paradigms (SwiftUI or Jetpack Compose), reactive state management, and unidirectional data flow
• A product-first mindset with a willingness and aptitude to flex across both iOS and Android using strong mobile fundamentals and AI translation workflows
• Maximizes the use of AI tooling while guiding the team in adopting modern AI practices
• Experience leading multi-quarter technical initiatives from scoping and architecture to launch and post-release monitoring
• Experience working with strongly typed API layers (GraphQL) and managing offline caching, state synchronization, and complex mobile data contracts
• Comfortable dealing with ambiguity, quick iteration cycles, and helping facilitate informed technical tradeoffs
• An aptitude and interest in bringing clarity and simplicity to complex and ambiguous problems

Bonus Points

• Production experience shipping features across both Swift/SwiftUI and Kotlin/Jetpack Compose
• Experience in the Fintech or banking industry building high-reliability, zero-defect mobile applications
• Familiarity with mobile infrastructure, including CI/CD pipelines, automated testing environments, and build & release systems
• Experience with MVVM or modern unidirectional architecture patterns

Additional Details

• A two-day travel to a Gusto office for onboarding is required for this position.
• Office presence expectation: Hybrid employees based in Denver, San Francisco, or New York City are expected to work from the office on designated days approximately 2-3 days per week.
