Data Scientist for the Search Quality Team

About the Team

Every search query made by Avito users goes through microservices and ranking algorithms written by our team. We are responsible for the quality of the final ranking of Avito search results and the technical operability of the search, helping colleagues bring product ideas to life on the search feed. We love "looking at data," searching for insights, and bringing ideas to life in algorithm code. We write in Python and Go, perform analytics on Spark, engage in machine learning, and are looking for motivated colleagues who can strengthen our team and bring an outside perspective to our work.

Examples of future tasks:

•  Create and configure ranking algorithms taking into account various aspects: buyer and seller satisfaction, monetization rules, etc.;
  

•  Develop, implement, and improve ML models used within the algorithms;
  

•  Manage liquidity – it is important for every seller's goods to potentially appear in the top of search results and be sold on Avito;
  

•  Conduct offline and A/B analysis of completed experiments;
  

•  Communicate with colleagues from product teams.
  

We expect that you:

•  Understand how key ML algorithms work (from decision trees to transformers);
  

•  Have experience developing and implementing ML models in production;
  

•  Know Python.
  

It would be great if you:

•  Have experience with search ranking or recommendations;
  

•  Are not afraid to write production code;
  

•  Have achieved high rankings in machine learning competitions;
  

•  Have done scientific work and enjoy research.
