Job Description

About the Team

Our teams are responsible for search ranking and recommendations. Our aim is to present the best of Etsy’s inventory. As an engineer on our team, you will play a major role in improving the shopping experience for millions of Etsy buyers. We’re a cross-functional group of engineers, data scientists, product managers, designers, and researchers.

With your help, we are giving our buyers better tools to find what they are looking for and to help them form a connection with our sellers. In this role, you will put your skills to use by helping us improve the ranking and suggestions of localized results through machine learning algorithms. You will also create workflows and pipelines to effectively transform data into appropriate results for our buyers. You will join a talented team of engineers to collaborate on all of these projects.

In this role, you will have the opportunity to work with our Data Science and ML team, Data Platform team and many more product squads. We’re a growing team with a huge impact that builds tools and platform capabilities for data scientists and ML engineers to access feature data, build machine learning models, test hypotheses and productionize them on our ML platform hosted in Google Cloud. We value empathy, communication and technical skills equally. Here’s a taste of the problems we’re solving:

  • How can we help someone find that perfect item, even when they don’t know what they’re looking for?
  • How do we rank millions of search results in a matter of milliseconds, so that we’re always surfacing the best of Etsy?
  • How can we maximize the relevance of search results over an enormous range of queries and buyers?
  • How can the search experience make Etsy come to life and feel as vibrant as the community of makers that’s behind it?
  • How can we understand buyer’s motives and interests to personalize their experience?
  • How can we help buyers to explore the breadth of Etsy’s inventory?

Our production systems rely on PHP, JavaScript, Java, Python and Scala; we are proud to have an engineering culture that encourages career growth and learning. You can learn more about our philosophies, tools, and some of the challenges we’ve been solving on our Engineering blog:

We are language-agnostic in our approach to interviewing.
