Software Development Engineer II Services, Inc.
 Seattle, WA


Recommending products to Amazon customers – yes, that is the space that we work in. We blend a variety of disciplines (such as recommender systems, data mining, NLP, big data and ML) to turn an intractable problem into a hard problem. For example: just because someone bought a purple dress does not mean that purple is the right color for them for all seasons; neither does it mean that you should recommend purple accessories. Just when someone buys a sofa, which rug in Amazon’s vast selection would it make most sense to pair with it? While there are other recommendation problems out there, none of them capture the scale of the problem, the rapidly changing inventory along with unique problems of fit, fabric and finish.

So how do we do it? We are a full stack team that own components all the way from dataset generation, high performance service oriented architecture to building great UIs that can surface recommendations in a pleasing and aesthetically appealing way. We work with engineers, scientists and product managers. As for techniques, we experiment with collaborative filtering, distributional similarities, and a diverse set of supervised learning algorithms. If you want to be on the cutting edge of personalization in e-commerce retail and reaching customers in a unique and valuable space, this is the team to be on! We have the mandate and ability to effect big changes, we just need the right person to begin.

As a Software Dev Engineer, you will work with other applied scientists, dev teams, engineers and product managers. You will own and build infrastructure that accesses terabyte of data to produce and deliver datasets with low latency and high reliability. The goal is to innovate new discovery features that can make a huge impact on the customer experience. What recommendations data could you use to make search more personalized? How can we use product similarity and sales data to augment and enrich our recommendations? How can we influence customers to drive long term value to Amazon?

We are looking for people who innovate, love solving hard problems, understand both technology and business, and have a great judgement skills. You will be able to build systems that will impact millions of customers and create multi-million dollar revenue opportunities, ship in just a couple of weeks and instantly measure the impact of what you have developed. And be able to go home and show your friends and family how you change the world!
