About the Role

At Uber, we ignite opportunity by setting the world in motion. We take on big problems to help drivers, riders, delivery partners, and eaters get moving in more than 600 cities around the world.

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 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. Be a humble mentor and trusted advisor. 
• Take a full-stack approach. Each project is unique and often requires a back-end, mobile and web component. You will be part of a cross-functional team which is developing the overall experience and architecture, the backend decisions impacting the rest of the stack.
• Manage scale and reliability. Our solutions support Uber's always-on marketplace. Maintaining this platform at scale requires constant investment in security, reliability and monitoring tooling.
• Up the bar on sustainable engineering by improving best practices, producing best in class of code, documentation, testing and monitoring.

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).
• Experience with multiple programming languages and data stores. We use programming languages like Go, Java, Python, data stores like Cassandra, DynamoDB, Redis and MQs like Kafka.

Bonus Points If

• Experience working in systems handling high volume payment transactions.
• Migrated services between microservices and monoliths and understand the practical tradeoffs of one architecture versus the other.
• Built large scale projects with stream processing and batch processing.
