LiveRamp is headquartered in San Francisco, California, with offices worldwide. Learn more at LiveRamp.com.

You will:

• Design, implement, and iterate on production-grade machine learning and statistical models that power core identity, entity resolution, and measurement capabilities.

• Analyze and transform large-scale, high-dimensional, and often messy datasets to uncover actionable insights, engineer robust features, and improve model performance and stability.

• Own end-to-end data science workflows-from problem framing, data exploration, and modeling through deployment, monitoring, and continuous improvement-in close collaboration with Engineering.

• Translate complex technical concepts and analysis into clear recommendations and narratives for product, engineering, and go-to-market stakeholders to inform roadmaps and prioritization.

• Define and track success metrics, build experimentation and evaluation frameworks, and tests to quantify the business impact of your work.

• Partner with Product Management to scope data-driven solutions that address customer needs, validate hypotheses with data, and de-risk new product investments.

• Contribute high-quality, well-tested, and maintainable code, documentation, and dashboards that make your work reproducible, observable, and easy to operate.

• Mentor and support other data scientists and analysts through code reviews, design sessions, and sharing best practices.

Your team will:

• Build and evolve data science capabilities that sit at the heart of LiveRamp’s identity and data collaboration products, working closely with engineering teams across the company.

• Tackle a diverse portfolio of problems, from improving core matching and graph-based algorithms to powering customer-facing features for targeting, measurement, and analytics.

• Collaborate cross-functionally with product, engineering, customer success, and go-to-market teams to ship solutions that are technically sound, operationally scalable, and aligned with customer needs.

• Maintain a culture of experimentation and scientific rigor, using well-designed tests, strong baselines, and clear metrics to guide decisions.

• Invest in shared tooling, libraries, and best practices that raise the bar for how data science is done and operationalized across LiveRamp.

About you:

• MS or PhD in Computer Science, Machine Learning, Statistics, Applied Mathematics, or a related quantitative field, or equivalent practical experience.

• 3+ years of experience designing, building, and deploying data science or machine learning solutions in a production environment.

• Proficiency in Python and SQL, along with experience using common data and ML libraries and frameworks (for example, pandas, NumPy, scikit-learn, or similar).

• Experience working with large datasets in a cloud environment and with modern data processing frameworks or warehouses (for example, BigQuery).

• Demonstrated ability to independently frame ambiguous business or product questions as concrete, testable data science problems.

• Strong analytical and problem-solving skills, with a focus on clear measurement, experimentation, and data-informed decision-making.

• Excellent written and verbal communication skills, including the ability to present complex technical topics to both technical and non-technical audiences.

• A product-focused mindset and a strong bias toward iterative execution-you are comfortable moving from idea to prototype to production quickly while incorporating feedback.

Preferred Skills:

• Experience with embeddings, representation learning, or large-scale similarity and ranking systems.

• Experience with approximate nearest neighbor search, vector databases, or other large-scale vector search technologies.

• Experience designing and implementing robust evaluation frameworks and monitoring for ML systems, including offline/online metric alignment and experimentation.

• Experience with Google Cloud Platform and its data and ML ecosystem (for example, BigQuery, Dataflow, Vertex AI, or similar).

• Familiarity with privacy-preserving data practices and governance, and interest in responsible and ethical use of data.

• Experience with identity, entity resolution, or graph-based modeling in advertising, marketing, or adjacent domains. The approximate annual base compensation range is $130,000 to $196,500. The actual offer, reflecting the total compensation package and benefits, will be determined by a number of factors including the applicant's experience, knowledge, skills, and abilities, geography, as well as internal equity among our team.
