About The Company
Cito is the digital transport solution for courier services, time-critical deliveries and the direct transport of goods. We are an innovative fast paced start up of the Volkswagen Group.
Our service creates an optimal user experience, increases efficiency and offers a first-class price-performance ratio with maximum fairness towards customers and partners. Cito’s mission is to transform the time-critical logistic market and establish simplicity, fairness, and transparency in the market:
Simplicity
We eliminate inefficiencies through our exceptional digital service, for our customers and logistic partners. From booking to billing, we leverage the potential of digitization so that customer, logistic partners and the transport itself are the focus.
Our solution seamlessly integrates with customers’ and logistic partners’ systems, ensuring a simply and efficient user experience.
Fairness
We establish fairness by offering our service to logistic partners free of charge. We provide a direct channel between customers and logistic companies. To ensure fairness, we pass value directly to the logistic partners without costly middlemen.
Transparency
We create industry leading transparency in the supply chain. Customers immediately know transport costs and logistic partners immediately know what they receive for their service. The customer knows which driver picks up the package, can contact him directly, live-track the delivery and receives immediate digital pick-up and delivery confirmation.
We are a young and highly motivated Berlin based team, with the courage and ideas to change the time-critical logistic market through digital technology.

This isn't an AI side project or prototype. You'll work on an AI system that automates real business processes for real customers.
High technical ownership
We don't want someone who simply works through a backlog. You'll have room to shape architecture, technology and the future of the product.
