## Description

The Markets Engineering team owns the infrastructure that keeps thousands of live markets accurate, up-to-date, and resolving correctly in real time - automation pipelines, external data integrations, and lifecycle systems that run continuously across a catalog spanning politics, sports, economics, and breaking news. When this layer works well, traders trust the platform. When it doesn't, markets go stale, resolution breaks, and confidence erodes fast., * Build and maintain automation pipelines that handle market creation, parameter configuration, and lifecycle updates across thousands of concurrent markets

 * Integrate sports APIs, news feeds, and other external data sources that drive market creation and resolution, including handling the messy, inconsistent data that comes with real vendors
 * Design pipelines for reliability, idempotency, safe re-runs, and fast failure detection through monitoring and alerting
 * Contribute to the data-driven systems that resolve markets accurately and on time
 * Debug production failures across markets infrastructure, often under time pressure, with senior support available
 * Review code and participate in design discussions as a full member of the engineering team
