Mobile Engineer Resume
Skills & ATS Keywords

Aim for 30 to 44 mobile-specific tools, SDKs, and platform features, organised into 7 to 8 named rows. Drop below 22 and you stop reading as a real iOS or Android shipper; push past 50 and the page starts to look like a sweep of every WWDC and Google I/O talk you watched. Each chip has to land in at least one bullet attached to an actual store release.

Sit it directly under the Profile Summary, before Work Experience. Parsers weight the top third of the file and recruiters scan top-down. Pushing the row to the bottom hides the Swift, Kotlin, SwiftUI, and Jetpack Compose signals the screen is looking for. Keep it to 7 to 8 categorised rows (iOS, Android, Cross-Platform, Architecture, Networking, Testing, CI/CD, Capabilities), never one long comma-soup line.

Read the JD twice. Pull out the 10 to 15 mobile tools, SDKs, libraries, and platform capabilities it names. Lay that list beside your Skills row and your bullets. Wherever the posting names a mobile tool that is honestly yours but missing from the page, slot it in: once in the Skills row, once in a bullet that proves you shipped with it. Finish with the ATS Checker so you know the parser caught each entry.

Front-End and React Developer resumes signal web work: browsers, Next.js, hydration, bundle-size. A Mobile Engineer resume signals shipped apps in the App Store and Google Play. Lead with the native stacks (Swift + SwiftUI for iOS, Kotlin + Jetpack Compose for Android), the cross-platform option where it applies (React Native New Architecture, Flutter, Kotlin Multiplatform), the store-distribution pipeline (Fastlane, TestFlight, Play Console, code signing), and mobile-grade observability (Crashlytics crash-free sessions, cold-start budgets, OOM). If your resume reads like Next.js with mobile sprinkled on top, a Mobile Engineer screen will pass you over.

Be honest about the split. Name the platform you actually shipped first (Swift + SwiftUI, or Kotlin + Compose), then add a smaller second row for the other side flagged as exposure or hobby work. A single line that mixes Swift, Kotlin, Combine, Coroutines, and Compose with no platform attribution reads as filler and a senior mobile reviewer clocks it inside one scan. Better to own one stack deeply than to claim both badly.

Lead with whatever you genuinely shipped to the store last. If the production app was Swift + SwiftUI, lead with native iOS, then add the React Native, Flutter, or KMP work as a second tier with its own bullets. If you owned a cross-platform Flutter or RN app end to end, lead with that, then prove the native fluency in a smaller row. Most 2026 JDs are happy with either ordering as long as one of the two stacks has a credible feature-shipped bullet attached.

Five numbers carry the most signal on a mobile resume: crash-free session rate (with the before and after, ideally above 99.9%), cold-start time (in seconds or milliseconds), MAU or DAU at the scale you shipped against, App Store and Play Store rating change, and releases owned per quarter or year. A bullet that names the platform (iOS, Android), the framework (SwiftUI, Compose), the metric, and the user scope clears both the parser and the recruiter scan. Generic “improved app performance” lines clear neither.
