Role overview

  • Build, improve, and operate recommender systems that tailor menus, content, and customer experiences across our brands.

  • Work with Product and Design to turn model outputs into simple, intuitive product flows.
  • Create modeling and measurement frameworks for LTV, CAC payback, attribution, and targeting across paid and lifecycle channels.

  • Provide clarity, feedback, and a psychologically safe environment where learning and experimentation are normal.
  • Help teams design strong A/B tests, interpret results, and balance speed with rigor.
  • Communicate clearly with non-technical stakeholders: what the model indicates, what it doesn’t, and where uncertainty remains.
