About the role
We are looking for a Machine Learning Engineer to own underwriting models at Grid, a Seattle fintech making 40,000 to 50,000 live credit decisions a month on a one to two second latency budget. You will read a user's bank transaction history, score the risk in their behavior, and ship the model that makes the call. Volume is growing fast as Grid scales ad spend, and the team is small enough that one person owns a model from ETL through deployment and monitoring.
What will you be doing?
- Train and deploy underwriting models that score risk from bank transaction and user behavior data
- Own the full path: ETL, feature engineering, training, deployment, monitoring, and the next iteration
- Ship live inference that returns a decision inside one to two seconds at growing volume
- Work on fraud detection, risk underwriting, and predictive analytics for payouts and repayments
- Help set the standard for ML practice at Grid as the team grows
Key Requirements
- Models you trained and put into production yourself, not models you consulted on
- Experience with large-scale transaction or behavioral data
- At least one full-time role at a startup or small team
- Python and SQL, with a real training stack (XGBoost, PyTorch, or TensorFlow)
- Fintech underwriting, lending, or fraud experience is a strong plus, not a requirement
- On-site in Seattle five days a week
