  • Build engaging and informative dashboards using visualization tools (e.g., Sigma, Tableau, Plotly), and use these tools to analyze trends and make recommendations.
  • Run periodic business reviews to keep senior leadership updated on how the company is operating from a bottoms-up view, and perform deep-dive analyses to understand the underlying causes.
  • Use business review insights to pinpoint growth opportunities, then drive that growth via product experiments and changes.
  • Mentor and guide junior data scientists in developing their analytical skills and communication.
You have...
  • Bachelor's degree in a relevant field (e.g., Data Science, Economics, Business Analytics, Information Systems).
  • 5+ years of experience in data science, business intelligence, or related roles.
  • Experience in programming (e.g., Python, R) to extract, transform, clean, and analyze large amounts of data.
  • Advanced SQL skills to build datasets that enable ad-hoc analyses and efficient visualization.
  • Expertise in data visualization tools such as Sigma, Tableau, or Looker for full-stack data analysis, insight synthesis, and presentation.
  • Outstanding problem-solving abilities and the capacity to distill complex data into concise explanations and actionable insights.
  • Excellent verbal and written communication skills with the ability to collaborate effectively with both technical and non-technical partners.
  • Able to relocate to and work in our New York or Pittsburgh office.
Exceptional candidates will have...
  • Master's degree in data science, economics, statistics, or an equivalent quantitative field
  • Experience managing, analyzing and communicating results to senior leadership
