  • Work closely with our product team to deliver models that we can productize and turn into prescriptive analytics and recommended actions
  • Collaborate with software engineers, data analysts and data architects, to design and train data models for downstream use
  • Extract, cleanse and transform raw data into business logic to ensure the right data gets to the right people at the right time
  • Use advanced programming languages, statistical models / algorithms and machine learning to identify trends and insights from data
  • Communicate and present findings and recommendations to stakeholders
  • Act as a champion for data quality and usability across the organization

What you’ll be bringing to the team :

  • Proficiency in SQL and a scripting language (preferred python) in a data science context
  • An entrepreneurial mindset and significant experience running experiments are key to this role
  • Extensive experience using data to solve business problems
  • Ability to break down complex projects into smaller work packages
  • Experience with a data warehouse (we use BigQuery)
  • Experience in performing data profiling, data mapping, and data quality validation
  • Experience with source control using Git or equivalent

  • Experience in AB testing / hypothesis testing and causal inference
  • Experience with BI tools (we use Looker)
  • An understanding of industry-standard design patterns for data warehouse data models
