Senior Data Scientist, ML— Fraud Prevention — Seattle, WA

Senior Data Scientist, ML— Fraud Detection & Effectiveness

The Opportunity

We are seeking an experienced Senior Machine Learning Data Scientist to build fraud and abuse detection models and measure how effectively they work. This role combines hands-on modeling with deep experimentation, evaluation, and analytics to improve detection and quantify business impact.

You will work across the fraud lifecycle — from modeling and ground-truth definition to performance measurement, monitoring, and executive-ready insights!

What you'll Do

• Build and tune ML models for fraud and abuse detection using statistical and classical ML techniques.

• Develop robust evaluation frameworks, datasets, and metrics to measure model and mitigation effectiveness.

• Analyze false positives/negatives, model drift, and emerging fraud patterns to continuously improve detection.

• Define ground truth, labeling approaches, and fraud taxonomies that support reliable model development and evaluation.

• Design experiments and evaluate tradeoffs across precision, recall, customer impact, and fraud loss.

• Build dashboards and metrics that translate detection performance into measurable business impact.

• Pressure-test models and data for leakage, bias, data-quality issues, and other sources of misleading results.

• Partner across engineering, product, policy, and risk teams to turn insights into detection improvements and business decisions.

What you'll need to succeed

• 8+ years in applied Data Science / ML, with experience building and evaluating production ML models.

• Strong foundation in statistical and classical ML, experimentation, model evaluation, and performance measurement.

• Strong hands-on Python and SQL skills working with large, complex datasets.

• Experience with model monitoring, drift, false-positive/false-negative analysis, and imperfect or delayed labels.

• Strong data visualization and storytelling skills — able to translate complex analysis into clear insights and recommendations.

• Strong analytical judgment, ownership, and ability to operate independently through ambiguity.

• Bachelor's or equivalent experience in Statistics, Mathematics, Computer Science, or related field; advanced degree a plus.

Preferred Attributes

• Experience in fraud, abuse, risk, identity, trust & safety, or other adversarial domains.

• Experience with anomaly detection, clustering, behavioral modeling, or prevalence estimation.

• Experience with labeling frameworks, weak supervision, active learning, or human-review systems.

• Familiarity with LLMs and AI-assisted evaluation/analysis.

• Experience evaluating multi-layered risk controls and automated decisioning systems.

Hybrid Work Model: This role follows a hybrid schedule, with a minimum of 3 days per week in the office.
