  • Analyze data to inform strategy and product/UX changes for user onboarding, engagement, retention, and monetization
  • Work closely with product managers, designers, and engineers to conduct A/B tests and iterate on better product improvements
  • Develop deep domain expertise about event and community
  • Work with our data warehousing systems to design, build, and maintain analyses and performance visualizations for users, major product initiatives, and other internal needs


  • Bachelors or higher degree in Statistics, Computer Science, Economics, Operations Research or similar quantitative field, or 3+ years of practical machine learning experience
  • Experience of developing productionized machine learning systems, such as Recommender, Search etc
