Senior backend developer C#. NET - Amsterdam


Company profile

Our key client is a disruptive digital used car platform based in Amsterdam, that enables customers to buy, lease and subscribe to high-quality used cars. Its mission is to create the leading marketplace for flexible mobility solutions in Europe centered on trust, efficiency and transparency.
They offer customers fixed prices, full ownership and maintenance history and a ‘no-questions-asked' 14-days period. Using a proprietary, data-driven model, they can match supply and demand across Europe. Our client is supported by a network of Delivery Stores, where customers can view the cars, receive consultation services before making a final purchase decision.
The European market for 3-4-year-old high-quality used cars is ripe for disruption. It is highly fragmented and inefficient, with low levels of transparency and consumer trust. At the same time, consumers are increasingly demanding convenient, transparent and flexible solutions. Our client is the first pan-European digital marketplace where consumers can find, buy or subscribe to their next car. They offer any car, anytime, anywhere.
There is significant growth potential for them, building on two of the biggest trends in mobility today: the growing market for Car-as-a-Service and increasing demand for high-quality, 3-4-year-old used cars. With 1.2 million cars on the road in Europe and a guaranteed supply of 250,000 well-maintained cars returned every year out of the Car-as-a-Service business, our client is able to deliver ‘any used car, anytime, anywhere' to customers in Europe.
