Mobile Engineer (iOS / Android) — Evlo AI, Washington, DC

About The Role

The role builds and maintains the native mobile applications that serve as the primary touchpoint for the product - covering the full iOS and Android stack, from UI implementation and offline data sync to deep linking, push infrastructure, and release engineering.

You will work in a small, senior mobile team with direct input into architecture decisions, shipping biweekly releases to a growing user base where app performance and stability are treated as product features, not afterthoughts.

Key Responsibilities

• Design, build, and ship native features across iOS (Swift/SwiftUI) and Android (Kotlin/Jetpack Compose), maintaining parity across both platforms

• Own end-to-end feature delivery: technical design, implementation, testing, App Store / Play Store release, and post-launch monitoring

• Integrate with REST and GraphQL backend services, handling auth, caching, background sync, and graceful offline behavior

• Improve app performance and stability - reducing cold start times, memory footprint, and crash rates using Firebase Crashlytics and Xcode Instruments / Android Profiler

• Build and maintain CI/CD pipelines for mobile (Fastlane, Bitrise, or GitHub Actions), including automated testing, signing, and phased rollouts

• Participate in code reviews, architecture discussions, and cross-functional planning with product, design, and backend teams

• Instrument and act on analytics and crash data to drive prioritization of reliability and UX improvements

What We Are Looking For

• 3–6 years of experience building and shipping production mobile applications to the App Store and/or Google Play

• Deep proficiency in Swift/SwiftUI, Kotlin/Jetpack Compose, or both - with strong understanding of platform conventions and lifecycle management

• Experience consuming RESTful and/or GraphQL APIs and building resilient network layers (URLSession, Retrofit, OkHttp, or equivalent)

• Track record of owning releases end-to-end, including store submission, review processes, and hotfix workflows

• Solid grasp of mobile architecture patterns: MVVM, modularization, dependency injection (Hilt, Swinject, or similar)

• BS in Computer Science or equivalent practical experience

• Bonus: experience with cross-platform tooling (React Native, Flutter) for internal tools, mobile security best practices, or contributing to open-source mobile libraries
