Freelance Data Science Manager Jobs in Virginia (NOW HIRING)

About The Team
The Personalization data science team builds and maintains search algorithms and recommender systems that are at the forefront of creating a modern, engaging, digital shopping experience for our customers. We see millions of customers every week across web and mobile. We deploy custom deep learning embedding models, ranking and segmentation algorithms, and are constantly testing new approaches. Our systems are used in dozens of product use cases across the retail and wholesale businesses, which means we partner with many diverse teams throughout the organization.
About The Role
Vehicle Recommender is our team's marquee data science product - a full-scale, modern software solution built on a custom embedding model. Launched in 2024 to replace our legacy system, it delivers intelligent, real-time, customizable product recommendations across our retail and wholesale businesses. We're looking for a data scientist who wants to own a product, not just build models. In this role, you'll develop deep technical expertise in our recommender system, but you'll spend just as much time working with partners across the business - understanding their needs, scoping use cases, advocating for adoption, and ensuring we deliver real value.
To be clear: this is a data scientist role, not a product manager role. You'll still be hands-on with data, experimentation, and model evaluation. But if you're the kind of DS who lights up in a roadmap discussion, loves translating ML capabilities into business terms, and wants to be the go-to expert that partners come to - this is your role. This role may or may not initially include direct reports, but that can depend on the individual candidate. It's ideal for an experienced data scientist interested in growing toward technical leadership or product-oriented career paths.
What You Will Do - Essential Responsibilities
Product Ownership & Partner Engagement
Serve as the primary point of contact for Vehicle Recommender across the organization - owning relationships with product managers, business stakeholders, and engineering partners
Drive adoption by helping partners understand what recommendations can do for them, scoping new use cases, and ensuring successful implementation
Own the roadmap for Vehicle Recommender in partnership with engineering and DS leadership - prioritizing enhancements, maintenance, and new capabilities
Translate between technical and business audiences; present to leadership, write strategy docs, and make the case for investment
Data Science & Technical
Develop deep technical expertise in the Vehicle Recommender system - how the embedding models work, how recommendations are generated and served, and how performance is measured
Design, execute, and interpret experiments (A/B tests, holdouts, pre/post analyses) to quantify impact and guide decisions
Partner with data scientists and engineers on feature development, model validation, and system monitoring
Stay current on recommender system research and best practices; bring informed perspective to technical decisions
Qualifications and Requirements
5+ years of experience in a data science role, preferably in e-commerce, marketplace, or a data-rich environment
Strong development skills and experience with Python for data manipulation, analysis, and model development
Solid foundation in statistics, including hypothesis testing, confidence intervals, and experimental design - you should be comfortable explaining why a test result is or isn't significant
Experience working with large datasets using tools like Spark, Databricks, or similar
Clear communication skills - you can explain a complex analysis to a PM or executive without losing them, and present a compelling argument for how and why a team will benefit from using recommendations
Genuine enthusiasm for how search and recommendation systems work and passion for continued learning
Bachelor's degree in a quantitative field (statistics, economics, math, engineering, or similar)
Advanced degree (Master's/Ph.D.) is preferred
