About the role

Software engineer role on Anthropic's Fraud Prevention team, building real-time risk decisioning, dispute/chargeback tooling, and fraud detection across payments, subscriptions, in-app purchases, and promotions. Collaborates with finance, support, legal, data science, processors, and platform partners to prevent fraudulent activity while preserving legitimate customer experience.

Responsibilities

  • Design and build real-time risk decisioning that scores transactions at authorization time, balancing fraud loss, approval rates, and latency constraints
  • Build tooling and automation for the dispute and chargeback lifecycle, from review queues to evidence collection and loss reporting
  • Engineer fraud signals at scale — device fingerprinting, BIN and issuer signals, velocity features, and cross-account linkage — and detect monetization abuse across subscriptions, trials, promotions, and in-app purchases
  • Own a portfolio of metrics — loss rate, dispute rate, authorization approval impact, and false-positive rate — rather than optimizing any single number
  • Lead investigations into emerging fraud patterns, building multi-layered defenses designed for attacker adaptation rather than point-in-time rules
  • Work cross-functionally with finance, support, legal, and data science, and with external payment processors and platform partners

Qualifications

  • Proficiency in Python, SQL, and data analysis tools
  • Experience building or operating fraud, risk, or abuse detection systems in production
  • Strong communication skills and ability to explain complex technical tradeoffs to non-technical stakeholders
