The Opportunity

We are building a first-of-its-kind consumer membership ecosystem from the ground up — and as we centralize CRM, loyalty, and marketing across every line of business at Beast. As our Senior Data Scientist for Customer Data & Marketing, you will be a foundational hire on the Data Science team, sitting in the central org and working across LOBs to turn that data into decisions, experiments, and compounding business impact.

This is a hands-on, cross-functional role. You'll run experiments, build measurement, and partner with marketing, product, and LOB leaders so every campaign, loyalty program, and CRM motion is grounded in real evidence — at 100M+ user scale.

The Product

You will be the data science anchor underneath a centralized customer data, CRM, loyalty, and marketing stack that serves every LOB at Beast. Your surface area includes:

• Experimentation & Analytics: The experimentation platform, measurement framework, and decision-making muscle that every LOB will lean on — A/B tests, holdouts, causal analysis, and the judgment to call what actually worked.
• CRM, Loyalty & Marketing: Segmentation, targeting, lifecycle analytics, and performance measurement across the centralized CRM and loyalty stack — so membership, Feastables, and every other LOB are operating off the same playbook.
• Customer Data at Scale: A unified view of the Beast audience built on top of our data & identity platform, powering both the immediate marketing roadmap and the longer-term personalization and AI-native use cases.

What You'll Do

• Own the experimentation program end-to-end across LOBs — design, power, analyze, and call experiments in CRM, loyalty, and marketing, and make sure the org actually acts on the results.
• Build the measurement foundation for centralized marketing: lifecycle metrics, campaign performance, loyalty program health, and the dashboards the business will run on.
• Partner directly with marketing, product, and LOB leaders — membership, Feastables, and beyond — to translate business questions into crisp, quantitative answers.
• Develop segmentation, targeting, and propensity models that drive real campaigns, not just slide decks.
• Partner with Data & Identity engineering to shape the customer data model — so the data you need for experimentation and marketing is actually there, and clean.
• Set the analytical bar for the org: how we measure, how we experiment, and how we decide. Use AI-native tooling and coding agents to move faster than a traditional DS function.

Who You Are

• Experimentation-Obsessed: You've run rigorous experimentation programs inside consumer products at scale. You know when to run a test, when to trust a quasi-experiment, and when to stop arguing and ship.
• Marketing & CRM Fluent: You've worked shoulder-to-shoulder with marketing, lifecycle, and loyalty teams — and you know how to translate fuzzy business goals into concrete metrics, tests, and models.
• Cross-Functional Operator: You're comfortable operating centrally and serving multiple LOBs. You can context-switch, prioritize ruthlessly, and build trust with stakeholders who don't all want the same thing.
• AI-Native: You aren't just curious about AI; you are burning through tokens, using coding agents daily, and integrating modern AI tooling deeply into your analytical workflow.
• Scrappy & Scaled: You have the startup experience to build from zero with a nimble team, plus the big-tech exposure to know what good looks like at consumer scale.
• Action-Oriented: You thrive in ambiguity and prefer shipping analyses that change decisions over producing beautiful but inert reports.
