Join us and be a part of shaping the future of urban mobility!

Some complain about traffic but some are actually doing something about it. Join us on our mission to reduce traffic in Istanbul by increasing the accessibility of sustainable shared mobility.

Who are we?

Volt Lines is the only technology-enabled player in the Turkish market competing against legacy incumbents and it reduces emissions and traffic by turning premium 16-seater buses into a viable alternative to single occupancy vehicles.

What we do?

In Istanbul, over 50,000 buses operate at 31% efficiency. These buses, which contribute to the city's traffic with empty seats, could also be the solution to its problem. Volt Lines is the only shuttle service provider that has both software as well as a transport service. This allows for optimal harmonization of the software and operation resulting in the creation of great experiences and services. Notable examples of these innovative services include DRT and Marketplace. DRT (short for Demand-Responsive Transport) was covered by a Harvard Business School case study that is being taught at the MBA school. Marketplace on the other hand allows companies to sell empty seats on their buses to neighboring passengers who are going in the same direction at the same time.

Let's work together to shape the future of mobility.

We're looking for a Mobile App Engineer to join us in shaping the future of urban transportation using the latest technologies.
