Responsibilities

• Design and ship customer-facing features for iOS using Swift and SwiftUI and/or Android using Kotlin and Jetpack Compose
• Build reliable integrations with REST or GraphQL services, including authentication, caching, synchronization, error handling, and offline workflows
• Define and evolve mobile architecture using established patterns such as MVVM, unidirectional data flow, modularization, and dependency injection
• Improve application quality through unit, integration, and UI testing with XCTest, XCUITest, Espresso, or equivalent frameworks
• Profile and optimize startup time, rendering performance, battery usage, memory consumption, and network efficiency
• Own mobile releases through CI/CD pipelines, feature flags, crash monitoring, and staged rollouts using tools such as Firebase, Sentry, Fastlane, or Bitrise
• Collaborate in design reviews and code reviews, document technical decisions, and mentor engineers on mobile development practices
