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 * Our projects get lots of visibility/exposure as our treatments are the front page of the app. * We run many live experiments and have a freedom to try new ideas and influence the business from the bottom-up. * The team values research: we have a generous conference budget and active paper reading group. * Unlimited PTO * GPUs
