Sumsub is the first AI-powered trust infrastructure for compliance operations at scale. It connects identity and business verification, fraud prevention, transaction monitoring, and risk workflows, helping teams reduce manual work and enter new markets. We are looking for a Senior Anti-Fraud Analyst to improve fraud detection accuracy and signal quality across Sumsub products. This is a hands-on role working with live production data. You will investigate fraud patterns, test and tune detection logic, and determine which signals, rules, and models can reliably identify suspicious activity.

Responsibilities

Explore live data to identify emerging fraud patterns, anomalous activity, and gaps in existing detection logic
Develop and tune fraud detection approaches using rules, supervised and unsupervised models, anomaly detection, and link-based analysis
Evaluate the accuracy, completeness, and predictive value of fraud signals and identify where they need to be fixed or improved
Analyse client traffic and alert flows, measure false positives and missed fraud, and recommend concrete improvements
Build and optimise baseline rule sets and proactive alerts for common and emerging fraud scenarios
Turn analytical findings into clear product recommendations and support complex, data-intensive client cases when needed

Requirements

4+ years of experience in anti-fraud, risk analytics, applied data science, or another analytical role involving complex data and anomaly detection
Strong knowledge of exploratory data analysis and classical machine learning, including supervised and unsupervised approaches
Practical experience with anomaly detection, clustering, and link-based or graph analysis
Hands-on experience in fraud prevention or fraud analytics
Strong Python and SQL skills
Hands-on experience with ClickHouse, Trino, Superset, dbt, DataHub, or comparable analytics tools
Strong judgement when working with raw and imperfect data: you can identify data-quality issues, bias, leakage, overfitting, and misleading model results
Ability to evaluate detection quality through false positives, false negatives, and other relevant metrics
Ability to explain complex findings through clear logic, numbers, and concrete examples
Confident but critical use of AI-assisted analytical tools, including the ability to validate their outputs
Fluency in English
