Applied Scientist

Upstart is an AI lending marketplace that uses advanced technology to expand access to affordable credit. The Applied Scientist will improve and develop machine learning models for borrower acquisition across marketing channels, conduct causal analysis and experimentation, and build production-ready data and modeling solutions in partnership with Machine Learning, Growth, and Marketing Platform Engineering teams.

What you'll do:

• Analyze historical model and campaign performance to identify opportunities to improve model effectiveness and marketing outcomes
• Develop and evaluate machine learning models, including researching new features and model architectures, to improve prospect selection and support new marketing use cases
• Design statistically rigorous experiments and model evaluations to measure causal impact, optimize campaign outcomes, and inform decisions
• Navigate complex, messy datasets and build reusable data pipelines, metrics, and analytical approaches that enable efficient model development and analysis
• Partner with Machine Learning, Growth, and Marketing Platform Engineering teams to translate business problems into research agendas, intermediate milestones, and production-ready solutions
• Expand machine learning capabilities beyond direct mail into lifecycle, email, digital, and other emerging marketing channels

What they're looking for:

• Master's Degree in Mathematics, Statistics, Economics, Operations Research or a related field
• Experience applying statistical and machine learning methods to modeling or data science problems
• Experience using Python for data analysis, data preparation, and machine learning model development
• Experience with causal inference and experimental design, including statistically rigorous evaluation of model or experiment performance
• The majority of our employees can live and work anywhere in the U.S or Canada (outside of Quebec) but are expected to spend high quality time in-person collaborating via regular onsites and in-person meetings
• PhD in Mathematics, Statistics, Economics, Operations Research or a related field (or its equivalent)
• Knowledge of causal machine learning methods and modeling approaches
• Ability to translate broadly scoped business problems into structured research questions, analyses, and modeling approaches
• Experience working across exploratory data analysis, machine learning research, experimentation, and production model development and scaling
• Ability to interpret complex experimental or modeling results and translate findings into actionable recommendations
• Experience applying machine learning to marketing, customer acquisition, lifecycle, or other growth use cases

Benefits:

• Digital-first work flexibility, with most employees able to work remotely from wherever they thrive in the US and Canada outside of Quebec
