  • Partner with ML engineers and backend teams to productionize data.
  • Analyze large transactional, fraud, and chargeback data to uncover trends, detect anomalies, and support deep-dive investigations.
  • Create and maintain real-time dashboards and reporting for key KPIs across Fraud, Risk, and Disputes for leadership, operations, and product teams.
  • Recommend data improvements to enhance fraud and chargeback detection capabilities and reduce false positives/negatives.
  • Act as a domain expert in fraud and dispute data, supporting internal investigations and external customer data queries.
  • Partner with Finance or Operations to answer questions about dispute costs, win/loss rates, and more.
  • Collaborate with Engineering to develop and maintain Airflow pipelines and ETL workflows to support scalable data pipelines.

Requirements

  • 5+ years of experience in data analytics, data science, or data engineering, preferably in fraud, risk, dispute, payments, or financial services.
  • Advanced SQL skills with a strong understanding of analytical functions, performance tuning, and ETL best practices.
  • Deep understanding of risk, fraud signals, disputes domain or related data patterns.
  • Strong data intuition: able to translate vague problem statements into structured data analysis or model features.
  • Experience with data visualization tools (Looker, Tableau etc).
  • Ability to translate business needs into technical solutions and data structures.
  • Comfort working with ambiguous data problems in a fast-paced, high-stakes environment.
  • Strong communication and collaboration skills—ability to work cross-functionally with Product, Engineering, and Ops.
  • Familiarity with Airflow, dbt, or equivalent ETL/ELT tooling.

Benefits

  • Multiple health insurance options
  • Flexible vacation time
  • Retirement savings program with company contribution
