Kotlin Software Engineer

Czym będziesz się zajmować?

What you'll do:

• Build real mobile apps that ship to the App Store and Google Play, running on Android and iOS from one shared Kotlin codebase
• Work with the most modern AI engineering tooling and test new tools as the ecosystem shifts month to month
• Make technical decisions together with engineers, designers, product managers and clients instead of simply implementing tickets

• Agentic coding is our default — Claude Code, Codex, Cursor, whatever's best that week
• We keep experimenting: no processes carved in stone, we try things, measure them and keep what works
• We work in small, tight, multidisciplinary teams of 3 to 5 people, all on one project — your responsibility and impact are bigger

• Work with a schedule that fits your lifestyle
• Private health insurance, MultiSport card, HearMe platform and more
• Work your way — remotely or from our Kraków office
• Projects for clients around the world

• Real curiosity — you try new tools on your own and follow where mobile and AI are heading
• Strong fundamentals: OOP, functional programming, design patterns, clean architecture (MVVM, MVI), clean maintainable code
• Commercial Android/Kotlin experience plus hands-on Kotlin Multiplatform, Coroutines and KMP concepts like expect/actual
• Compose Multiplatform or Jetpack Compose plus SwiftUI, and enough Swift and Xcode to work at the platform boundary
• KMP libraries such as Ktor, Koin, SQLDelight/Room, plus Android Studio, Gradle and Git
• Fluency in AI tools (Claude Code, Codex, Cursor or similar) to generate, review and improve code
• English min. B2 to work with clients
• In the application form, share a link to your AI-built test, tool or video: a shipped app, a repo or open-source project, or a 2–3 min video of you working with AI coding agents

• Several years building mobile products used by real users
• Defining technical direction and defending architectural decisions (time, quality, cost, complexity trade-offs)
• Ownership of production quality (stability, performance, maintainability metrics)
• Mentoring regulars and juniors, unblocking the team, surfacing risks early
• Representing the technical side with clients (English min. C1)
