Senior Data Scientist, Customer Data & Marketing

MrBeast • San Francisco, CA

15h • Hybrid

About The Position

Beast Industries is building a first-of-its-kind consumer membership ecosystem from the ground up. As they centralize CRM, loyalty, and marketing across every line of business, the customer data becomes one of the most valuable assets. As the Senior Data Scientist for Customer Data & Marketing, you will be a foundational hire on the Data Science team, sitting in the central organization and working across lines of business to turn that data into decisions, experiments, and compounding business impact. This is a hands-on, cross-functional role where you will run experiments, build measurement, and partner with marketing, product, and line of business leaders so every campaign, loyalty program, and CRM motion is grounded in real evidence at a 100M+ user scale. The product includes an experimentation platform, measurement framework, and decision-making capabilities for A/B tests, holdouts, and causal analysis. It also involves CRM, loyalty, and marketing functions such as segmentation, targeting, lifecycle analytics, and performance measurement. Additionally, it focuses on customer data at scale, building a unified view of the Beast audience to power the marketing roadmap and longer-term personalization and AI-native use cases.

Requirements

• Rigorous experimentation programs inside consumer products at scale.
• Experience working shoulder-to-shoulder with marketing, lifecycle, and loyalty teams.
• Ability to translate fuzzy business goals into concrete metrics, tests, and models.
• Comfortable operating centrally and serving multiple LOBs.
• Ability to context-switch, prioritize ruthlessly, and build trust with stakeholders.
• Deeply integrating modern AI tooling into analytical workflow, using coding agents daily.
• Startup experience to build from zero with a nimble team.
• Big-tech exposure to know what good looks like at consumer scale.
• Thrive in ambiguity and prefer shipping analyses that change decisions over producing beautiful but inert reports.

Responsibilities

• 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.

Benefits

• Competitive Salary
• Generous Medical (Blue Cross Blue Shield), Dental, Vision and company-paid Life Insurance
• Company contributions to employee Health Savings Accounts (HSA)
• 401k Plan with Safe Harbor company-matching
• Flexible vacation policy and paid company holidays
• Company-provided technology package
• Relocation assistance where applicable, including travel and company-provided housing for the first 90 days
