Senior Software Development Engineer

3+ months agoWindhof, Luxembourg


Our ambition is to be Earth's most customer-centric company, where customers can find and discover anything they might want to buy online at the lowest possible prices. How do we get there? What does it take to solve our customers' everyday online shopping problems? Do our customers find what they are looking for? If they find what they are looking for, is it competitively priced? And if they find what they are looking for a competitive price, can it be delivered fast enough? In today's ongoing COVID-19 pandemic, how do we make sure that people across the globe can still get essential goods delivered to their homes as fast as possible? How do we reach people who are not native English speakers when there are over 7000 languages spoken in the world? How do we facilitate a seamless payment experience when there are over 180 currencies used in the world with diverse payment methods? How do we solve problems for people who have different shopping behaviours from our regular shoppers?

Senior SDE @Amazon:
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 peers that make the Amazon magic happen. Whether it's ownership of existing software or working on new products, you will lead the design and implementation of large-scale efforts from the technical perspective. You'll not only code, but also drive the direction of the software architecture, and work proactively with other teams on integration projects. Our Senior SDEs enjoy a great deal of autonomy. In addition to owning the architecture of a larger product, you will lead code reviews, mentor engineers, and drive important technical decisions.
Senior SDEs at Amazon are above all problem solvers, those we trust most in making technical decisions for how we build our software. They know every line of code we write matters in building great products. As the technical experts on their teams, Senior SDEs come from all different backgrounds, some deeply specialized, while others have a more generalist background. In any case, they are able to keep an eye on big picture while still keeping a finger on the pulse of the details; using both to inform their architectural and design decisions. Senior SDEs also have an eye on the bigger picture and influencing business strategy. Product managers and non-technical stakeholders will depend on you to balance technological demands with business needs.

Luxembourg - Wëllkomm zu Lëtzebuerg!
Our teams in Luxembourg are in the middle of everything. As the headquarters for Amazon's European operations, Luxembourg is home to leadership teams from across the company. The office is a great opportunity to work closely with both business and technical leads on critical projects and grow your career.
The country itself is in the middle of Europe. Set among a picturesque background of medieval ruins, Luxembourg City is home to numerous multinational companies which creates a diverse city. 7 out of 10 residents of Luxembourg City are expats, who hail from 167 different countries. In addition to having three official languages: Luxembourgish, German, and French, English is widely spoken. Simply put, Luxembourg works hard to make expats feel at home. For those who love to travel, the country is centrally located making it easy to visit cities such as, Paris, Cologne, and Brussels by train. Barcelona, Rome and Berlin can be reached in less than two hours by air.

Amazon's goal is to expand into 150 countries by 2022. Luxembourg is the home of International Consumer (Intech) teams focusing on international expansion of our websites around the world.
