Description

A Berlin-based startup is hiring a Senior Full-Stack Developer for Value, an employee app for care facilities that combines a bonus system and benefits, a messenger, a newsfeed, pulse surveys and health offers. The role spans the Laravel backend and REST API for the iOS and Android apps, the Vue.js web version and admin area, and native mobile development with Swift/SwiftUI and Kotlin/Jetpack Compose. Beyond implementing requirements, you shape the product together with the founders, own features from the first idea to release and can take on responsibility for infrastructure and the technical platform. Active use of AI tools in everyday development workflows is expected, alongside the ability to understand, debug and critically evaluate code without AI.
