    • Shape the core experience of users and developers interacting with SumUp's Android ecosystem.
    • Work closely with the product and design team to build components that are maintainable, usable, beautiful and consistent.
    • Embed accessibility best practices into every component (content descriptions, touch target size, color contrast, font scaling).
    • Implement dynamic theming support (light/dark mode, brand variations) that can be switched at runtime or via configuration.
    • Provide hands-on technical support to product teams to deliver company priorities, such as the upcoming brand refresh.
    • Review code contributions, enforce design‑system conventions, and guide engineers on best practices for reusable UI development.
    • Identify and address tech debt proactively to ensure a high bar for engineering excellence and codebase health.

    What We're Looking For

    • You have 3+ years of professional Android development experience, with expertise in Kotlin and modern Android frameworks.
    • You have 2+ years of experience working with Jetpack Compose.
    • You strive for clean code, and are flexible to balance pragmatism and perfection.
    • You have a strong grasp of testing best practices: knowing what to test, why, and how to write resilient tests.
    • You have a strong eye for detail and are committed to accessibility.
    • You are self-motivated, have a clearly structured working style, and possess good verbal and written English communication skills.
    • You enjoy keeping up to date with advancements in the Android ecosystem and are excited about sharing your knowledge with the Android community.

    Bonus Points (Nice to Have)

    • Experience building and maintaining design systems / component libraries for Android, including theming, style guides, and reusable UI components.
    • Experience navigating complex codebases and refactoring existing code
    • Experience working with Kotlin Multiplatform
