Mobile Engineer (iOS / Android)

Evlo AI; Austin (TX); On-site; USD 120,000 - 180,000; Full time

Job summary

Evlo AI in Austin, TX is seeking a hands-on mobile engineer to build native iOS and Android experiences. You will own critical parts of the mobile stack, optimize performance, and ship features with high polish.

Collaborate across platform teams, implement offline-first data layers, and contribute to CI/CD pipelines for app releases. The role requires 3–7 years in software engineering with strong mobile app shipping experience, and deep knowledge of either Swift/SwiftUI or Kotlin/Jetpack

Qualifications

• 3–7 years of software engineering experience, including at least 3 years building and shipping consumer or production mobile apps.
• Proficiency in iOS (Swift, SwiftUI, UIKit, Combine) or Android (Kotlin, Jetpack Compose, Coroutines/Flow), with willingness to work across both platforms.
• Experience integrating backend APIs (REST/GraphQL), handling networking edge cases, auth flows, and background work.
• Strong understanding of mobile architecture patterns: MVVM, MVI, modularization, and dependency injection (e.g., Hilt, Swinject).
• Track record shipping releases through App Store/Google Play, including feature flags, staged rollouts, and hotfix processes.
• Bonus: experience with cross‑platform frameworks (React Native, Flutter, KMP), mobile CI/CD at scale, or app security.

Responsibilities

• Build and ship features natively in Swift/SwiftUI and Kotlin/Jetpack Compose, or via cross‑platform frameworks where appropriate to the product surface
• Design and integrate REST and GraphQL APIs, handling authentication, pagination, caching, and real‑time updates
• Improve app performance — cold start times, render performance, memory footprint, and bundle size — using profiling tools like Instruments and Android Profiler
• Implement offline‑first data layers with local persistence (Core Data, Room, or SQLite) and robust sync/reconciliation logic
• Own test coverage across unit, integration, and UI automation suites (XCTest, Espresso); maintain CI pipelines for builds and releases via Fastlane and App Store/Play Store release processes
• Monitor production quality using crash reporting (Sentry, Firebase Crashlytics) and analytics; triage and resolve regressions quickly
• Participate in architecture reviews, code reviews, and mentoring of mid‑level engineers on the team

• Bachelor's degree in Computer Science or equivalent practical experience
• Bonus: Experience with cross‑platform frameworks (React Native, Flutter, KMP), mobile CI/CD at scale (Bitrise, Xcode Cloud), or deep work on push notifications, deep linking, or app security (certificate pinning, biometric auth)
