This is how we deliver progress, create engagement and keep our global community of learners motivated. So far, over 32,000 tutors have given more than 15 million lessons to learners from over 175 countries.

  • Work closely with data analysts, data scientists and backend engineers to understand business requirements and provide data ready for analysis.
  • Apply software engineering best practices like version control and continuous integration to the analytics code base. Select and instrument data quality tools and processes;

  • Strong curiosity, problem-finding and problem-solving skills;
  • Creative mindset and a proactive attitude towards the creation and evaluation of new solutions;
  • Good written and verbal communication skills. B2 English is a must;

Nice to have:

  • Experience developing critical data processes to standardized definition of KPIs and taxonomy of events across medium/big organizations;
  • Knowledge of coordination tools (Airflow, Luigi, Jenkins, etc.);
  • Working experience with the AWS stack/Google Cloud Platform.

Why you’ll love it at Preply:
