Compose Multiplatform information

What are the key skills and qualifications needed to thrive as a Compose Multiplatform Developer, and why are they important?

To thrive as a Compose Multiplatform Developer, you need a solid background in Kotlin programming, UI/UX design principles, and experience with multiplatform mobile and desktop application development. Familiarity with Jetpack Compose, IntelliJ IDEA, Android Studio, and version control systems like Git is typically required, along with knowledge of cross-platform frameworks. Strong problem-solving skills, adaptability, and effective communication help developers collaborate and innovate in a rapidly evolving environment. These abilities are crucial for building efficient, maintainable, and user-friendly apps that work seamlessly across platforms.

What are some common challenges faced by developers working with Compose Multiplatform, and how can they be addressed?

Developers working with Compose Multiplatform often encounter challenges related to platform-specific differences, ensuring consistent UI/UX across Android, Desktop, and Web, and keeping up with rapid framework updates. Addressing these challenges involves thorough testing on all target platforms, leveraging shared code as much as possible while isolating platform-specific logic, and staying engaged with community forums and documentation for the latest best practices. Collaborating closely with designers and platform experts also helps in creating a seamless user experience.

What is Compose Multiplatform?

Compose Multiplatform is a modern UI framework developed by JetBrains that allows developers to build user interfaces for multiple platforms—such as Android, desktop (Windows, macOS, Linux), and web—using a single codebase in Kotlin. It leverages the declarative programming paradigm, making UI development faster and more maintainable. Compose Multiplatform is an extension of Jetpack Compose, which was originally designed for Android, but now supports cross-platform development with a consistent API. Its goal is to simplify creating beautiful and responsive UIs across devices.

What is the difference between Compose Multiplatform vs Android Developer?

AspectCompose MultiplatformAndroid Developer
Primary FocusCross-platform UI development for multiple platformsAndroid app development primarily for Android devices
Required SkillsKnowledge of Kotlin, Compose, multi-platform architectureJava/Kotlin, Android SDK, UI design for Android
Work EnvironmentDeveloping apps for Android, iOS, desktop, and webDeveloping Android-specific applications
Industry UsageUsed by companies targeting multiple platforms with a single codebaseUsed by companies focusing solely on Android apps

Compose Multiplatform enables developers to create UI for multiple platforms using Kotlin, whereas Android Developers focus on building applications specifically for Android devices. While both roles require Kotlin knowledge, Compose Multiplatform emphasizes cross-platform architecture, making it suitable for developers aiming for multi-platform deployment. Android Developers typically specialize in Android SDK and UI design for Android, working within the Android ecosystem.

Job description

About Cantina:
Cantina Labs is a social AI company, developing a suite of advanced real-time models that push the boundaries of expression, personality, and realism. We bring characters to life, transforming how people tell stories, connect, and create. We build and power ecosystems. Cantina, our flagship social AI platform, is just the beginning.
If you're excited about the potential AI has to shape human creativity and social interactions, join us in building the future!
About the Role:
As a Kotlin Multiplatform Engineer at Cantina, you'll be the architect of our shared-code strategy - building the foundation that powers our experiences across Android, iOS, and web from a single Kotlin codebase. You'll work at the cutting edge of the KMP ecosystem, shipping production code to real users on multiple platforms, while keeping platform-specific layers feeling truly native.
We're looking for a Kotlin expert who has been in the trenches with KMP - someone who has wrestled with interop edge cases, navigated the wasm target, and shipped Compose Multiplatform UI that feels polished everywhere.
What You'll Do:
  • Design and build shared KMP modules covering networking, data persistence, business logic, and domain models used across Android, iOS, and wasm targets.
  • Ship production-grade Compose Multiplatform UIs that feel native and performant on Android, iOS, and web.
  • Build optimized platform-specific targets - leveraging Swift/Obj-C interop for iOS and Kotlin/Wasm for web - to meet the performance and UX bar of each platform.
  • Architect clean platform-expect/actual boundaries and maintain Kotlin/Native and Kotlin/JS interop layers.
  • Set up and manage Koin Multiplatform for dependency injection across all targets, ensuring clean and testable module graphs.
  • Collaborate with platform teams (iOS, Android, web) to align on shared APIs, versioning, and release cadences.
  • Drive KMP best practices across the organization - tooling, testing strategies, CI/CD for multiplatform builds.
  • Lead development of new AI and media-driven features within the shared codebase.
  • Participate in architecture reviews and uphold high standards for shared module design and testability.

What You'll Bring:
  • 8+ years of software engineering experience with deep, expert-level Kotlin - you know the language spec, not just the idioms.
  • Real-world, production KMP experience: you've shipped KMP code that real users ran on Android, iOS, and/or wasm - not just toy projects or internal tools.
  • Hands-on Compose Multiplatform experience: building shared UI across multiple targets with platform-specific adaptations.
  • Experience with Koin Multiplatform for dependency injection across KMP targets in production codebases.
  • Solid understanding of Kotlin/Native memory model, freezing, and interop with Obj-C/Swift APIs.
  • Experience targeting Kotlin/Wasm and/or Kotlin/JS, including the Compose for Web stack.
  • Fluency with multiplatform build tooling: Gradle multiplatform plugin, source sets, target configuration, and CI pipelines.
  • Strong grasp of coroutines, Flow, and structured concurrency - understanding how they behave across targets.
  • Ability to write readable, maintainable, thoroughly documented, and well-tested shared code.
  • Bonus: experience with KMP libraries (Ktor, SQLDelight) in production environments.
  • Bonus: contributions to the KMP/CMP open-source ecosystem or close familiarity with JetBrains' roadmap.

Compensation:
The anticipated annual base salary range for this role is between $180,000-$230,000. When determining compensation, a number of factors will be considered, including skills, experience, job scope, location, and competitive compensation market data.
Benefits:
  • Competitive salary and generous company equity
  • Medical, dental, and vision insurance - 99.99% of premiums covered by Cantina
  • 42 days of paid time off, including:
    • 15 PTO days
    • 10 sick days
    • 15 company holidays
    • 2 floating holidays
  • Generous parental leave & fertility support
  • 401(k) retirement savings plan
  • Lifestyle spending account - $500/month to use however you'd like
  • Complimentary lunch and snacks for in-office employees
  • One Medical membership, and more!
