Kleinanzeigen operates Germany's dominant online classifieds platform, serving 35 million monthly users across categories from consumer goods to real estate. The tech stack (Spring, AWS, Elasticsearch, Kafka, MySQL) reflects a mature, event-driven architecture built for scale. Current hiring acceleration across product, marketing, and sales roles—paired with active work on a customer data platform and professional-seller experience—suggests a shift toward monetization beyond the free-listing core, with real-estate vertical redesign and payments strategy development as near-term priorities.
