About the role
ABOUT US
Launched in 2019, Constructor is an AI-first ecommerce search and discovery platform that helps shoppers find the right products at the right time and enables leading global e-commerce brands to drive meaningful revenue and conversion gains.
As a member of the ML Recall team, you will improve the e-commerce experience for hundreds of millions of users across the world by building the retrieval layer of our search engine.
The mission is to make sure the product a shopper looks for is always among the results - for any query, in any language, in a few milliseconds.
ABOUT THE JOB
Your primary focus will be search retrieval and visual solutions:
- Search Recall. A modern retrieval stack with dense and sparse models, plus query understanding. Latency is a strict requirement, so quality vs speed tradeoff is constant.
- Visual and multimodal search. End-to-end visual solutions: image search, shop the look, visual recommendations.
- Models as a platform. Our team owns a wide range of deep learning models, and other teams build on top of them.
WHAT MAKES THIS INTERESTING
- Multi-domain, multi-language, at scale - 40+ languages, 20+ domains. The models need to generalize across all of them - without per-customer rules or overrides.
- Real room for R&D.
