Description Scale at Amazon is, well, really big. There are few companies out there building at our scale and complexity, and even fewer in Europe. As a Senior Software Development Engineer (Senior SDE), you’ll be part of a small group of diverse peers that make the Amazon magic happen. With ownership of existing software and building new products, you will lead the design and implementation of largescale efforts from the technical perspective. You’ll not only code, but also drive the direction of the software architecture, and team practices. Our Senior SDEs enjoy a great deal of autonomy and are looked up to as technical leaders. In addition to owning the architecture of a larger product, you will lead code reviews, mentor engineers, and drive important technical decisions. Opportunities are available in Madrid and the following are some of the teams hiring for Amazon Stores in Spain: Kindle Books Tech team is building a 200+ person tech hub in Spain.

We’re off to a big start. After launching in 2015 in the United States, Amazon Business quickly reached $1 billion in annualized revenue. Now we’re expanding outside the United States. AB is addressing a new set of customer needs in a vast new market segment. While we can rely on Amazon’s existing capabilities in user experience, convenience, selection, pricing and logistics, we need to re-invent core parts of the buying experience to serve the needs of businesses and other institutional buyers. Furthermore, as we expand outside the U.S., we need to listen closely to local customer needs and tailor our approach to the requirements of local customers in Europe and Asia.

Name another company building Anytime Pay, which we built to allow employees to withdraw pay as soon as they've earned it, prior to payday. Name another company using machine learning to ensure that employees are paid accurately. We really are having fun and making history in an area that - let's face it - is probably pretty boring at other companies.
