BUILDING A RECOMMENDER SYSTEM FOR JOBS
JUN 2021 - AUG 2023
Goal
Building a two-tower recommender system that is integrated into a full information retrieval pipeline. Inspired by the architecture of YouTube, we extended our existing full-text search infrastructure with a recommendation engine that re-ranks search results based on a deep neural network. It uses several hundred datapoints of the current job seeker to find correlations to other job seeker’s preferences in order to find the perfect job for that particular user.
My role and responsibilities
  • Lead a cross-functional product team of data engineers, machine learning engineers and data scientists through the implementation phases with rapid prototyping
  • A/B testing the new recommendation engine against the plain-vanilla search infrastructure finding an uplift of 20% in conversion rate
Used technologies
Python, PyTorch, Keras, MLFlow, BERT/USE embeddings, ElasticSearch
