Android Developer

Role Overview

• You will get to know frameworks, tools, clients and projects — through sparring sessions and code reviews directly within the team
• You will join one of our ongoing Android projects and take on initial tasks or bug fixes
• You will jointly plan a new project as an evolution of an existing Android platform
• Once onboarded, you will take on responsibilities such as:
• Becoming Tech Lead for one of our larger Android projects — the primary contact for the team and the client
• Planning project phases independently and supporting colleagues with input and fixes
• Taking responsibility for our internal product
• Actively driving the adoption of AI in our projects and processes
• Participating in code reviews and giving clear, early feedback to Design and Product Management
• In the long term, you can take overall project responsibility toward clients and further develop into roles such as Tech Lead, Kotlin Multiplatform specialist or AI consultant.

Requirements

• Kotlin is your language — you know Jetpack Compose and Android components inside out
• App architectures and client/server communication (REST, WebSocket, JSON) are part of your daily work
• Testing is not an afterthought for you — you have experience with unit, integration and end-to-end tests and know tools like JUnit, Espresso and Mockk
• You know how apps get into the Play Store: Fastlane, Bitrise and the deployment process are familiar to you
• You know the Android ecosystem well enough to make sound project decisions — platforms, devices, features
• Android Studio, Gradle and Git are part of your daily setup — you already use AI tools like Claude Code, Copilot or Codex
• German at C1 level is essential — our clients communicate in German and formulating clear requirements is part of the job
• You bring experience from complex projects with interfaces to Design, Product Management and other developer teams
• Soft skills that make a difference — you communicate clearly internally and externally, in writing and verbally
• You proactively contribute ideas and are open to questioning existing structures
• You want to continue developing professionally — and actively make time for it
• A degree in Computer Science or a comparable qualification — for senior roles we value solid formal knowledge
• Experience with Scrum/Agile — Scrum certifications (Developer/Master) are a welcome plus
• Knowledge of complex system architectures: whitelabeling, streaming, CMS
• English at B2 level — for collaboration with international colleagues

Tech Stack

• Android
• Gradle
• JUnit
