## About the role

Every buyer, seller, and lender on Alt is acting on a number our models produced. Alt Value prices the card. The underwriting model sizes the advance. Those two systems are the difference between a marketplace and a handshake, and they are the closest thing we have to a moat.

## What they're looking for

- 7+ years engineering, with 5+ years building and shipping production ML/AI models
- Production-grade Python and SQL , including custom feature-engineering pipelines — not just off-the-shelf scikit-learn. Time-decay weighting, leakage-safe k-fold cross-validation, cascading fallback and imputation logic
- Gradient-boosted or ensemble estimators trained and validated against strict accuracy tolerances, with segment-specific tuning by category or asset type
- LLMs and foundation models in production , for both internal tooling and user-facing product
- MLflow or a comparable tool for experiment tracking and model registry/versioning
- Production model-serving on AWS that was yours — capacity planning, autoscaling, and diagnosing memory and timeout failures at scale
