Job Description
Position Summary... What you'll do... Distinguished Architect — Identity, Authentication & Fraud Prevention As the Distinguished Architect for Identity, Authentication, and Fraud Prevention, you’ll be principal technical authority defining the end‑to‑end architecture for customer identity, access, and fraud risk, spanning account security, payment fraud, and chargeback reduction. You’ll modernize our identity platforms, fraud decisioning, and ML‑driven risk systems to deliver secure, low‑friction, and loss‑efficient experiences at massive retail scale. You’ll partner across security, payments, fraud, and data science teams to translate trust, risk, and loss outcomes into durable technical designs. What you’ll do Set the target architecture across identity and fraud Define reference architectures, guardrails, and roadmaps spanning CIAM and authentication, account security (ATO, adaptive auth), payment fraud and chargebacks , and ML‑driven risk decisioning. Ensure platforms are designed for AI/ML‑enabled, real‑time decisions at scale. Modernize core identity, fraud, and payments risk platforms Evolve authentication services, fraud gateways, and decision engines to support risk‑based login and checkout, reduce payment fraud and chargebacks, and deliver low‑latency, highly available, cost‑efficient systems.
