Mobile Engineer (iOS / Android)

Evlo AI; Denver (CO); In loco; USD 110.000 - 160.000; Tempo pieno

Descrizione del lavoro

Evlo AI in Denver is seeking a hands-on Mobile Engineer to design, build, and ship native iOS and Android apps that power millions of users. You will own features end-to-end, optimize performance, and help uphold quality across the mobile stack.

You will collaborate with backend, design, and product teams in a fast-moving environment, focusing on crash-free experiences, robust offline behavior, and smooth release cycles, with emphasis on architecture and testing.

Competenze

• 3–6 years of professional mobile engineering experience with at least one app shipped and maintained at significant scale (100K+ MAU preferred).
• Deep proficiency in Swift and iOS (UIKit and/or SwiftUI) or Kotlin and Android (Jetpack Compose), with strong fundamentals in the second platform.
• Solid understanding of mobile architecture patterns: MVVM, modularization, dependency injection (Hilt, Swinject), and reactive programming (Combine, Coroutines/Flow, RxSwift).
• Experience with offline storage, synchronization, and conflict resolution (Core Data, Room, SQLite, Realm).
• Hands‑on with testing practices: unit, integration, and UI testing (XCTest, Espresso, Detox).
• Bachelor's degree in Computer Science or equivalent practical experience.
• Bonus: Kotlin Multiplatform, React Native/Flutter experience, mobile security (certificate pinning, secure storage), or contributions to open‑source mobile libraries

Mansioni

• Design, build, and ship features in Swift/Kotlin (or cross‑platform Kotlin Multiplatform/React Native where appropriate) for production iOS and Android apps
• Own end‑to‑end delivery of user‑facing features: architecture, implementation, testing, release, and post‑launch monitoring
• Integrate REST and GraphQL APIs, push notifications, deep linking, and background processing with robust offline‑first behavior
• Improve app performance and reliability: startup time, memory footprint, ANR/crash rates, and battery efficiency, using tools like Instruments and Android Profiler
• Automate CI/CD pipelines with Fastlane, Xcode Cloud, or Gradle; manage app store releases, phased rollouts, and feature flags (LaunchDarkly or similar)
• Instrument analytics and crash reporting (Firebase, Sentry, Amplitude) and use the data to drive prioritization and fixes
• Participate in code reviews, architecture discussions, and mentoring of junior engineers
