Job summary

Koombea is seeking an AI-First Native Mobile Developer to build scalable native apps for iOS and Android, leveraging AI as a core workflow. You will own features end-to-end within an AI Pods structure, collaborating with designers and delivery managers to raise the bar on AI-driven development.

Remote in LatAm with 5+ years of native mobile experience; strong Swift/Kotlin skills and familiarity with AI coding tools are essential for this role at Koombea.

Qualifications

• 5+ years of native mobile development experience.
• Strong professional experience with Swift (SwiftUI and/or UIKit) building native iOS apps.
• Strong professional experience with Kotlin (Jetpack Compose, Coroutines/Flows) building native Android apps.
• Experience shipping and maintaining production apps on both the App Store and Google Play.
• Strong programming fundamentals and native mobile architecture design.
• Strong understanding of the app lifecycle, concurrency, memory management, and platform constraints on iOS and Android.
• You can reason about unfamiliar codebases, debug complex issues, refactor with intent, and recognize when systems require structural improvements rather than surface-level fixes.
• Experience reviewing and refactoring AI-generated code.
• Experience with CI/CD for mobile (Fastlane, GitHub Actions, Bitrise, or similar).
• Good English communication, written and spoken.

Responsibilities

• Build and ship native iOS applications with Swift/SwiftUI and native Android applications with Kotlin/Jetpack Compose.
• Own features end-to-end on both platforms, keeping architecture and behavior consistent between iOS and Android.
• Use agentic AI coding tools as your default workflow: writing context documents, managing AI-generated output, and running parallel tasks.
• Design native mobile architectures (MVVM, MVI, Clean Architecture) that are clean, scalable, and easy for both humans and AI agents to work with.
• Review and refactor AI-generated code with the same rigor you'd apply to any PR.
• Integrate REST APIs, third-party SDKs, and native device capabilities.
• Debug and resolve issues related to performance, crashes, memory, and scalability on both platforms.
• Contribute to code reviews, technical decisions, and engineering best practices.
