We served 4 billion trips in 2017 and are currently operating in more than 600 cities, across 65 countries, enabling 15 million daily trips, and connecting over 75 million monthly active riders with 3 million active drivers. We are currently making significant investments into our systems to support the continued growth of Uber at a much larger scale, globally.

About the Role

Uber is looking for full stack Software Engineers to join our payments team based in Amsterdam, at the heart of our international engineering efforts. We are looking for collaborative and pragmatic technologists who will design, implement and deliver delightful and innovative payments experiences on the web and backend which we are building from scratch.  

The payments team builds products that we integrate into a growing number of Uber businesses, collaborating closely with these teams. We work with many teams across the globe, from Rides to Driver, EATS, JUMP Bikes, Uber for Business and Uber Lite, with more coming up. This is an opportunity to influence and build the next generation of user-facing payments solutions from scratch, working alongside designers, data scientists, user researchers, and product managers.

We are looking for someone with a passion for designing and building experiences that are highly reliable and used by millions of people on a daily basis. Our systems visualize payments information and ensure accurate and on-time payments. We ensure accurate and on-time payments where money is collected from customers and partners are paid timely. In 2017 this meant collecting $37 billion in gross bookings which were made with over 4 billion trips.
