Mobile Engineer (iOS / Android)

Evlo AI; Seattle (WA); On-site; USD 140,000 - 190,000; Full time

Job summary

Evlo AI is hiring a hands-on Mobile Engineer to design, build, and ship consumer mobile features on iOS and Android. You will own end-to-end development from API contracts through UI implementation, testing, and release rollout.

Join a product-focused team that prioritizes crash-free performance, latency, and smooth user experience. Expect modern tooling, CI/CD, and mentoring opportunities in a fast-paced Seattle environment.

Qualifications

• BS in CS or equivalent practical experience.
• Strong fundamentals in concurrency, memory management, and mobile architecture patterns (MVVM, MVI).

Responsibilities

• Design, build, and ship user-facing features across iOS (Swift/SwiftUI) and Android (Kotlin/Jetpack Compose) in tight two-week release cycles.
• Own feature development end-to-end: API contracts with backend engineers, UI implementation from Figma specs, instrumentation, and release rollout.
• Build and maintain shared architecture - modularization, offline-first data layers, and deep link routing - used across both platforms.
• Improve app performance and reliability: cold start times, memory footprint, ANR/crash rates, and battery efficiency, tracked via Firebase Crashlytics and Sentry.
• Implement automated testing strategies: unit tests, screenshot/UI tests (XCUITest, Espresso), and CI pipelines using Bitrise or GitHub Actions.
• Participate in staged rollouts, feature flag management (LaunchDarkly), and hotfix triage during release windows.
• Contribute to code reviews, mobile guild discussions, and mentoring of mid-level engineers on the team

About The Role

The role builds and maintains the native mobile applications that millions of users interact with daily - owning features end-to-end from design handoff to App Store and Play Store release.

This is a hands-on engineering position on a product-focused mobile team, where release quality, crash-free rates, and interaction latency are treated as first-class engineering metrics, not afterthoughts.

Key Responsibilities

• Design, build, and ship user-facing features across iOS (Swift/SwiftUI) and Android (Kotlin/Jetpack Compose) in tight two-week release cycles
• Own feature development end-to-end: API contracts with backend engineers, UI implementation from Figma specs, instrumentation, and release rollout
• Build and maintain shared architecture - modularization, offline-first data layers, and deep link routing - used across both platforms
• Improve app performance and reliability: cold start times, memory footprint, ANR/crash rates, and battery efficiency, tracked via Firebase Crashlytics and Sentry
• Implement automated testing strategies: unit tests, screenshot/UI tests (XCUITest, Espresso), and CI pipelines using Bitrise or GitHub Actions
• Participate in staged rollouts, feature flag management (LaunchDarkly), and hotfix triage during release windows
• Contribute to code reviews, mobile guild discussions, and mentoring of mid-level engineers on the team

What We Are Looking For

• 3-6 years of experience building and shipping consumer mobile applications to the App Store and/or Google Play
• Deep expertise in Swift or Kotlin, with strong command of SwiftUI or Jetpack Compose for modern declarative UI
• Experience integrating REST and GraphQL APIs, handling auth, pagination, caching, and offline sync patterns
• Track record of debugging production issues using crash reporting tools (Crashlytics, Sentry) and profiling tools (Instruments, Android Profiler)
• Familiarity with CI/CD for mobile: automated builds, code signing, TestFlight/Play Console release management
• BS in Computer Science or equivalent practical experience; strong fundamentals in concurrency, memory management, and mobile architecture patterns (MVVM, MVI)
• Bonus: experience with Kotlin Multiplatform or cross-platform frameworks, mobile backend development, accessibility (WCAG), or local notification/push infrastructure (APNs, FCM)
