What’s this team like at Etsy?

Search Retrieval is a product engineering team that strives to improve the relevancy of search results for Etsy buyers. We apply the latest techniques from machine learning, natural language processing, and information retrieval research at Etsy’s scale, including:

• Distributed, highly efficient random walk based graph recommendation engine written in Rust.
• Graph neural networks that learn from billions of previous interactions between our buyers and sellers.
• Inverted indexes that incorporate the latest research in sparse retrieval. 
• Deep neural dense retrieval models powered by Transformers and fast approximate nearest neighbor (ANN) search

 What does the day-to-day look like?

Our team of applied scientists, ML engineers, data analysts, and product managers work as a cross-disciplinary team in a primarily remote setting. In our team, you will:

• Strategically pick ideas from the latest in ML research with the highest potential to benefit Etsy buyers and quickly prototype them on Etsy data.
• Propose pragmatic long-term project plans that demonstrate value early through fast iteration. 
• Create large, scalable data ETL pipelines for new features to power our models. 
• Optimize ML models to meet latency SLAs at the scale of Etsy production traffic and launch live A/B experiments to test our hypotheses.
• Analyze and learn from experiment results, and disseminate our findings throughout Etsy and beyond through conference publications and talks.
• Lead high code quality and engineering standards in the team.
• Of course, this is just a sample of the kinds of work this role will require! You should assume that your role will encompass other tasks, too, and that your job duties and responsibilities may change from time to time at Etsy's discretion, or otherwise applicable with local law.
