  • Prepare and deliver regular capacity analysis, commentary, and recommendations to Supply and Finance on long-term trends to inform infrastructure strategy and company budgets.
  • Influence technology choices for data analysis tools. 

Who you are:

  • You excel at communicating complex insights to both technical and non-technical stakeholders.
  • Expertise in time series analysis applied to forecasting is especially desirable.
  • Experience with capacity planning and/or supply chain management is beneficial but not required.


  • 2+ years of industry experience involving quantitative data analysis to solve real-world problems.
