- Drive measurable fraud loss reduction Lead the technical approach for payment fraud prevention, anomaly detection, and dispute/chargeback reduction, including strong feedback loops from outcomes back into models and controls.
- Raise reliability and decision quality Define SLAs/SLOs and KPIs across identity and fraud systems (availability, latency, false positives, MTTR). Champion resiliency, observability, and data quality for always‑on trust platforms.
- Accelerate risk experimentation Shape APIs, policy frameworks, and data contracts that enable rapid A/B testing of fraud controls and champion/challenger model iterations without degrading customer experience.
- Influence and up‑level the organization Provide architectural stewardship, deep design reviews, and mentorship to Staff/Principal Engineers and EMs, multiplying impact across identity, fraud, payments, and data platforms.
What you’ll bring
- Large‑scale identity and fraud platform design Experience building and operating CIAM/authentication systems and real‑time fraud and payments risk platforms at scale.
- Fraud, payments, and chargeback expertise Strong domain knowledge in payment fraud, disputes/chargebacks, anomaly detection, and adversarial behavior.
- AI/ML and data pipeline fluency Hands‑on experience with fraud ML systems: feature pipelines, model deployment, real‑time inference, experimentation, and monitoring.
- Reliability and velocity leadership Proven ability to improve SLAs/SLOs and engineering KPIs through sound architecture and operational excellence.
- Executive‑level influence Clear storytelling that ties architecture to outcomes such as fraud loss, chargeback rate, approval rate, and customer trust.
