Write your story with a career at Zip

You’ll be the primary owner and driver of Zip’s foundational marketing ML models, including:

Customer Intent Modeling

You’ll build predictive models that go beyond behavioral pattern recognition to surface the motivations driving customer decisions.

• Determine the appropriate modeling approach, evaluate competing methodologies, and establish standards for model explainability, monitoring, and ongoing refinement.
• Build models designed not just to predict what a customer will do next, but to understand why, so we can meet them at the right moment with something genuinely useful.

Next Best Action Framework

You’ll translate model outputs into concrete, prioritized recommendations that inform customer communications and product experiences.

• Build the decisioning layer that turns predictive insights into actionable recommendations.
• Enable meaningful impact across multiple parts of the organization by helping teams determine the right action for the right customer at the right time.

Marketing Mix Modeling and Attribution

• Translate model outputs into credible investment recommendations that help us allocate budget and resources intelligently across paid, owned, and partner channels.
• Build and maintain the models and methodologies that underpin our understanding of marketing effectiveness and acquisition performance.

Technical Leadership and Business Partnership

• You’ll provide technical guidance and peer review to other data scientists and analysts, share reusable methods, and help raise the quality of marketing science practices across the team.
• You’ll also serve as the primary conduit between your work and business stakeholders, translating complex modeling and insights into clear, actionable recommendations. This is a role where ownership, independence, and strong communication skills are key.
