About the company

Zenjob is a digital job placement platform in Germany that helps students and part-time workers find and book shifts through a mobile app. Users browse and filter shifts by location or type of work, apply with one click, and receive about half of their gross wage a few days after completing a shift. Partner companies post available shifts, and Zenjob earns revenue by charging them a fee for each successful placement, while job seekers access the service for free. The platform operates in more than 39 German cities and serves both job seekers and businesses needing temporary staff. Compared with traditional job hunting, Zenjob streamlines the process by eliminating lengthy applications and scheduling, offering immediate, on-demand access to flexible work. The company's goal is to simplify earning side income and connect students and other part-time workers with temporary staffing needs through an easy-to-use app.
