Director of Data Science, Credit - Mission Lane

Mission Lane is combining the power of data, technology, and exceptional service to pave a clear way forward for millions of people on the path to financial success. We're looking for a Director of Data Science to own the strategy and technical leadership behind Mission Lane's credit acquisition models, reporting to the Sr. Director, Data Science.

The Impact You'll Make

Someone hits submit on a credit card application, hopeful this is the “yes” that lets them start building toward something: a car, a home, a little more room to breathe. You'll lead the strategy and the team behind decisions like that one. Keeping every decision accurate and fair as circumstances shift makes this work interesting and rewarding, every day.

Mission Lane is young, but we’ve landed in an exciting, stable stretch of maturation: still moving toward what we’re going to become, with plenty of room for you to help shape it.

What You'll Own

• Mission Lane's credit acquisition modeling strategy, translating the company's growth and underwriting goals into a roadmap that balances approval rates, portfolio performance, and fair lending practice
• Technical leadership for the data scientists building and maintaining acquisition models, setting the bar for model design, code quality, and production rigor
• Model risk and monitoring practices that keep acquisition models compliant, explainable, and accurate as underwriting conditions change
• Cross-functional alignment with Credit Risk, Portfolio, Data Engineering, and company leadership on how acquisition modeling fits into Mission Lane's broader risk appetite
• A growing scope as acquisitions-adjacent growth initiatives roll into the team, giving you room to shape how the function expands

Our Core Tech Stack

• Python and the Python data stack (numpy, polars, scikit-learn)
• LightGBM, DVC, Kubernetes, Airflow, Google Cloud
• Chalk (our feature store)

You'll Thrive in This Role If

• You stay anchored to the business problem you're solving, keeping the modeling technique in service of the goal.
• You're curious by nature, the kind of person who wants to understand how the pieces fit together.
• You've made predictions where the outcome doesn't show up for a year or more, and you build in the discipline that requires, including practicing sound model risk management.
• You can mentor and raise the technical bar for experienced data scientists without needing to be the smartest person in every room.
• You partner naturally with people outside data science, translating technical trade-offs into decisions the business can act on.

Minimum Qualifications

• PhD in a quantitative field and 5+ years of experience in a related role, or a BS/MS in a quantitative field and 8+ years of experience in a related role
• Created, deployed, and managed supervised learning models in a production environment for high-impact applications
• Direct experience hiring, coaching, and developing data scientists as their manager
• Applied data science to credit risk, underwriting, or another long-horizon, regulated prediction problem, such as insurance
• Writes tested, reviewed, reproducible code, for data pipelines and model training alike, and works fluently in the Python data stack
• Able to travel ~4-6+ times per year for high quality in-person collaboration

Preferred Qualifications

• Direct experience in consumer lending; credit card acquisitions, specifically
• Familiarity with Mission Lane's broader ML tooling ecosystem, including Chalk, BentoML, or DVC
• Experience partnering directly with executive leadership on modeling strategy
