## About the Role

* A PhD in a quantitative field and 3+ years of experience in a related role, or a BS/MS in a quantitative field and 7+ years of experience in a related role
 * Has created, deployed, and managed supervised learning models in production systems for vital applications
 * Shares best practices for software engineering and can help experienced data scientists work through complex technical problems, especially operationalizing and evaluating models for real-world use
 * Practices solid software engineering fundamentals (test-driven development, code review, refactoring) and works fluently in our core tech stack
 * Interested in a wide range of ML tooling, from established tools (Spark, Kubernetes, Airflow, MLFlow) to emerging ones (Chalk, BentoML, DVC)
 * Experience assuming project leadership on a workstream, working independently with guidance focused on priorities and key objectives
 * Ability to travel ~4+ times per year for high quality in-person collaboration

## Description

* Implementation of the data science roadmap for collections, serving as the primary technical point of contact day to day, and setting the standard for rigor and production quality across the data scientists, consultants, and contractors working alongside you
 * End-to-end models that anticipate how customers are likely to respond to different kinds of outreach, and that shape which approach Mission Lane uses and when
 * Durable internal modeling practices that reduce how much of this work needs to run through outside consultants over time

Our core tech stack includes:
Python and the PyData stack (numpy, polars, scikit-learn), LightGBM, DVC, Kubernetes, Airflow, Google Cloud, MLFlow, BentoML, and Chalk, our feature store.

You'll thrive in this role if:

 * You adapt quickly to a new domain. You don't need collections experience in order to pick up the business context fast and connect it to the technical problem.
 * You can trace a modeling choice back to the business problem it's solving, keeping the modeling technique in service of the goal.
 * You can explain your reasoning clearly enough that consultants, contractors, and full-time teammates alike can pick up your standard and run with it.
