We are looking for a Data Scientist to help Amazon Search NLP to build an Search evaluation data set. It is a short (5-month) full-time job starting ASAP. We are looking for an individual interested in search and search relevance (quality), with the patience to analyze hundreds of queries and search results, and with the ingenuity to propose new leads.
