Staff Data Scientist - MoneyLion

Staff Data Scientist

We are seeking a Staff Data Scientist to join the Data Science team at Engine by Money Lion. Engine by Money Lion is the definitive search engine and marketplace for financial products, connecting consumers with personalized financial offers across loans, deposits, credit cards, and more through its robust API. Data Science powers Engine's offer recommendations, dynamic pricing, and enhanced decisioning across our network, working closely with financial partner managers and product teams to develop cutting-edge models that drive value across the consumer journey through our complex marketplace funnels.

In this role, you will own critical model systems end-to-end—from data engineering and feature pipeline management through model development, deployment, and real-time serving. Your models will generate direct revenue impact in real time, and your data solutions will affect millions of users daily. You will lead technical initiatives across recommendations, pricing, and marketplace optimization, collaborating deeply with engineering, product, and business stakeholders to bridge the gap between advanced machine learning and tangible business outcomes.

• Own and develop production ML models for real-time recommendations, pricing, and conversion prediction across the Engine marketplace.
• Design, build, and manage feature pipelines and data transformations in our data warehouse (e.g., Redshift, Snowflake) using tools like dbt, Airflow, and SQL to ensure high-quality, timely features for model training and serving.
• Lead the design, execution, and analysis of large-scale A/B tests and experiments, translating results into actionable product and model improvements.
• Collaborate closely with product managers, partner managers, and business stakeholders to translate complex business problems into well-scoped data science projects.
• Work hand-in-hand with engineering teams to deploy, monitor, and maintain ML models in production—including real-time serving infrastructure.
• Drive best practices across the team in model development, code quality, documentation, experiment design, and reproducibility.
• Contribute to the evolution of our MLOps platform and tooling, ensuring scalable and reliable model lifecycle management.
• Present findings, model insights, and strategic recommendations to executive and non-technical stakeholders with clarity and business context

• Bachelor's or Master's degree in Computer Science, Statistics, Mathematics, Physics, Economics, or a related quantitative field (or equivalent professional experience).
• 7+ years of experience across data science, machine learning, and data engineering, including:
• Designing and shipping production ML models and advanced analytics in applied, production-oriented settings using Python, SQL, and ML frameworks.
• Building real-time or near-real-time ML systems for recommendations, pricing, bidding, or similar use cases.
• Working with data warehouse technologies (Redshift, Snowflake, Big Query) and building/managing data pipelines (dbt, Airflow, Spark).
• Strong foundation in statistics, probability, experiment design, and machine learning theory.
• Experience working with ML platforms and infrastructure (Sage Maker, Spark, Ray, MLflow, or equivalent).
• Comfortable doing software engineering when needed—writing application code in Python/Scala/Java, contributing to APIs, containerizing services (Docker, Kubernetes), or building CI/CD for model deployments.
• Excellent communication skills—effective with both technical and non-technical audiences.
• Experience in fintech, financial services, or marketplace/auction environments is a strong plus.
