At Devx Staffing, we've spent years building deep expertise in Kotlin recruiting. We understand the nuances between Android Kotlin engineers who optimize Jetpack Compose, coroutines and the Android SDK for smooth mobile UX; backend Kotlin developers who build Ktor or Spring Boot services, use coroutines and JVM interoperability for scalable APIs; and multiplatform/KMM engineers who share business logic across iOS and Android while managing Kotlin/Native interop and platform bindings. That expertise lets us screen for practical skills—coroutines, Flow, Kotlinx.serialization, Gradle Kotlin DSL, Compose, Ktor, Spring, Kotest and MockK—and match companies with talent that fits their architecture, performance and deployment needs.
