About Uber

Uber is changing the way the world moves. Here at Uber, our mission is to bring transportation for everyone, everywhere. 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 Senior Software Engineers to join our payments team based in Amsterdam, at the heart of our international engineering efforts. We are looking for passionate and pragmatic technologists who are able to design, implement and deliver scalable and resilient systems. We look for collaborative role models who are approachable and can mentor the talented people they work with.

We are looking for someone with a passion for designing, building and scaling highly-available, mission-critical systems that support millions of users on a daily basis. Our systems ensure accurate and on-time payments where money is collected from customers and partners are paid timely. In 2017 this meant processing $37 billion in gross bookings which were made with over 4 billion trips.

What You’ll Do

• Provide technical leadership and vision in designing, implementing, testing and rolling out the next generations of our payments systems.

What You’ll Need

• 7+ years of relevant engineering experience.
• Advanced, inside-out knowledge of at least one OOP programming language.

• Experience in building distributed and concurrent systems, knowing the tradeoffs between stateful/stateless and synchronous/asynchronous architectures.
• Good level of understanding of fault-tolerant systems and multi-datacenter/cloud architectures.
• Thorough technology and architecture understanding both on a theoretical level (e.g. RDBMS vs. NoSQL) as well as on an applied level (e.g. Redis vs. Cassandra, Java vs. Javascript).
• Applied knowledge of software engineering, as well as coding best practices that minimize tech and architecture debt.
• Commitment to quality, performance, and efficiency.
• Good written and verbal communication skills, including the ability to write detailed technical documents.
