About the role
Chime's Data Science & Machine Learning team powers decisions across the company, from how we protect members to how we build products for them. We're looking for a Director to lead that team through its biggest shift yet: moving from traditional models to a modern, AI-driven approach built on transformers and foundation models. You'll lead managers and staff-level engineers, define what great ML looks like at Chime's scale, and rebuild the practice around it. If you want to shape the future of ML at a company where it directly affects members' financial lives, this is the role.
In this role, you can expect to
- Lead and grow Chime's ML organization, managing managers and staff-level engineers across all of Chime's ML work.
- Set the vision and roadmap for moving Chime's models from traditional approaches to transformer- and foundation-model-based systems.
- Coach your managers to build strong, high-performing teams, and raise the technical bar across the practice.
- Shape the architecture of Chime's ML platform, including how we train, fine-tune, serve and scale models on a modern GPU-based stack.
- Define what good ML looks like at Chime: standards for model development, evaluation, deployment and monitoring.
- Partner with product, engineering, risk and business leaders to turn ML into measurable impact for members.
- Make the call on when to build, buy or fine-tune, and explain the trade-offs clearly to executives.
To thrive in this role, you have
- Deep machine learning expertise, with a well-formed point of view on transformer and foundation models a
