## About the role

We are seeking a Senior Staff Machine Learning Engineer to define and accelerate how we leverage agentic AI to transform machine learning models and modeling workflows. This high-impact role focuses directly on modeling leverage —enhancing model quality and velocity—rather than building general infrastructure.

## What they're looking for

- 9+ years of experience in ML engineering, applied ML, or a related field, with substantial production impact
- Senior Staff-level technical leadership and a record of influencing direction across teams
- Deep modeling expertise and strong fundamentals in data, objectives, architectures, optimization, evaluation, and experimentation
- Concrete examples of using agentic AI or AI coding tools to produce better ML outcomes—not just faster code generation
- Ability to design guardrails and evaluations that make autonomous or semi-autonomous workflows trustworthy
- Strong coding ability in Python and fluency with modern ML frameworks and data tooling
