The Risk Engineering Behind a 1 Million SKU Automated Pricing Engine

At massive scale, automated pricing becomes financial infrastructure. This architecture manages over 1 million SKUs and 500,000 daily updates using blast-radius containment, multi-phase validation, and exposure modeling to prevent systemic pricing failures. By separating optimization from risk enforcement and adding strict guardrails, the system reduced incidents from 3% to 0.1% while achieving 99.9% uptime.
