DATA SCIENTIST

Data Scientist (Corporate)At Sally Beauty Holdings, Inc., our purpose is to inspire a more colorful, confident, and welcoming world. We are the leader in professional hair color, selling and distributing professional beauty supplies across 11 countries through our Sally Beauty and Beauty Systems Group businesses. Sally Beauty offers products for hair color, hair care, nails, and skin care to retail customers looking for salon quality products at a value price. Beauty Systems Group, branded as Cosmo Prof or Armstrong McCall stores, along with its direct sales consultants, sell professionally branded products intended for use and resale by salons to retail consumers.We are seeking a hands-on Data Scientist to build the models and data products that power how SBH understands and activates its customers. This is a technical individual-contributor role for a data scientist who is equally comfortable engineering a feature pipeline in Databricks, defending a model's validation approach, and explaining the resulting business recommendation to a non-technical stakeholder.Your mission is to increase Customer Lifetime Value (CLV) by developing the predictive assets behind hyper-personalized CRM campaigns, retention strategies, and proactive churn reduction. You will own models end to end, from problem framing and feature engineering through training, validation, deployment, and ongoing performance monitoring, and ensure they run reliably in production rather than living in a notebook.This role sits at the intersection of advanced analytics and commercial strategy and is critical to advancing SBH's Understand & Activate Customer agenda. You will work closely with Data Engineering, CRM, Marketing, and Merchandising partners, and will help mature our Databricks environment from a place where analysis happens into a platform that delivers repeatable, monitored, production-grade customer intelligence.ResponsibilitiesModel Development & Advanced Analytics (50%)Predictive Modeling: Build machine learning models through all phases of development, design, feature engineering, training, evaluation, validation, and implementation, using Python. Core use cases include churn and retention modeling, propensity-to-buy, CLV prediction, customer persona/segmentation, and next-best-action recommendations.Segmentation Strategy: Move beyond basic demographics to build behavioral, psychographic, and value-based segments (e.g., RFM, K-Means clustering, propensity tiers) that CRM and Marketing can activate directly.Advanced Methodologies: Apply Market Basket Analysis (MBA), survival analysis, uplift/incrementality modeling, and recommender approaches to uncover cross-sell, up-sell, and hidden revenue opportunities.Statistical Rigor: Produce summary statistics, distribution and correlation studies, and disciplined feature selection; apply confidence intervals, cross-validation, and appropriate model performance validation to every deliverable.Ad Hoc Agility: Prioritize and deliver critical ad hoc analysis supporting the SALLY plan and forecast, balancing speed with statistical accuracy.Data Engineering for Analytics & Productionization (30%)Data Pipelines: Develop and maintain the customer 360 view and supporting data pipelines in Databricks using Python, PySpark, and SQL. You should be comfortable building your own pipelines to enable your analysis rather than waiting on others.Production-Ready Code: Convert proof-of-concept code into production-ready, re-usable components integrated into products and services, with attention to scalability (compute, memory, I/O, model serialization, caching).MLOps: Automate ML processes such as scheduled scoring and model re-training, and implement monitoring for data drift, model drift, and accuracy degradation. Contribute to impact assessment, back-testing, explainability, reproducibility, and data quality checks.Engineering Discipline: Follow source control, peer code review, and automated testing practices (Git/Azure DevOps); contribute to CI/CD for analytics assets.Experimentation, Test & Learn (20%)Test Design: Design and analyze A/B and multivariate tests for email, SMS, push, and in-app campaigns to optimize engagement, conversion, and incremental lift.Audience Construction: Build statistically sound test and control audiences in partnership with CRM, ensuring balance, mutual exclusivity, and reproducibility.Rigorous Measurement: Execute the Test vs. Control measurement framework and apply guardrails for attribution, incrementality, and performance readouts.Standardization: Apply and help maintain Standard Operating Procedures (SOPs) for customer campaign measurement, reporting hygiene, and data integrity.Lifecycle Optimization: Support data-driven customer journeys (Onboarding, Growth, Retention, Reactivation) with the models and audiences that make them work.Knowledge, Skills & Abilities RequirementsEducation & ExperienceEducation: Master's degree in mathematics / Statistics/Data Science and Analytics, Computer Science, Economics, Physics, or a related field required. Master's degree preferred.Experience: 4+ years of hands-on experience in data science, applied machine learning, or customer analytics.Industry: Experience in Retail, CPG, e-commerce, or subscription/loyalty-driven businesses is highly desirable.Technical SkillsCore Languages: Advanced proficiency in Python (pandas, NumPy, scikit-learn) and SQL. Experience with R is a plus.Big Data & Cloud: Hands-on experience with Databricks, Spark/PySpark, Delta Lake, and a major cloud environment (Azure preferred; AWS/GCP acceptable).Machine Learning: Regression, classification, clustering (K-Means), tree-based and boosting methods, survival analysis, recommender systems, and dimensionality reduction (PCA). Exposure to deep learning frameworks is a plus.Statistical Knowledge: Solid grounding in hypothesis testing, confidence intervals, experimental design, cross-validation, and basic probability and linear algebra.MLOps & Engineering: Experience with model deployment and monitoring (e.g., MLflow), model re-training automation, drift detection, version control (Git), and code review practices. Exposure to REST APIs, containerization, or orchestration tooling is a plus.Presentation: Strong PowerPoint and Excel skills, with the ability to build an executive-ready narrative.Competencies & AttributesAbility to "connect the dots" across disparate data points to form a cohesive business recommendation. A self-starter who operates independently, seeks opportunities to scale and automate, is comfortable challenging the status quo, and can present findings credibly to non-technical senior leadership.
