  • Developing and enhancing search algorithms that improve retrieval precision and personalize the search

The second is what we call visual search, and in this area we focus on:

  • Improving and introducing new capabilities to visual search like math solving
  • Developing and enhancing search algorithms that improve retrieval precision and personalize the search
  • Leveraging mobile devices capabilities to provide a better search experience

You will have the chance to work with top-class scientists, engineers, and domain experts and to drive the data science process of our technology end-to-end.
