Some of our projects, to give you an idea of what you could work on, are:

* LTR: Making search more relevant and personalized

* Bandits: how do you sample from the posterior of an arbitrary deep-learning model?

* Online Learning: how can we learn incrementally instead of in batches? How do you update an embedding?

* Multi-objective optimization. How can you balance conversion and revenue objectives?

* Representation Learning: building a product graph from our catalog using large-scale language models

* Semantic search: “chocolate milk” vs “milk chocolate” or not showing french fries and french toast of a “french” query

Perks:

* Salary + RSUs

* We run many live experiments and have a freedom to try new ideas and influence the business from the bottom-up.
