Responsibilities

• Own carrier performance monitoring. Build and run the daily/weekly monitoring of shipping health — margin, on-time delivery, label generation success, scan rates, surcharge and refund rates, and CX contact volume — define the topline carrier KPIs, surface degradation early, and drive issues to resolution with the right internal and external owners.
• Own carrier pricing. Understand and size every carrier price change (rate cards, surcharges, fuel, zone remapping), decide with Product/Eng and business leadership whether and how to pass changes through, coordinate customer communications and CX readiness, and hold carriers accountable to advance notice on pricing and data changes.
• Lead disruption response. Monitor and respond to carrier API changes, tariffs and regulatory shifts (e.g., de minimis changes), carrier policy updates, and weather events — quarterbacking coordinated cross-functional responses with Product, Engineering, CX, Trust & Safety, and Public Policy.
• Own shipping cost integrity. Run the invoice reconciliation process across all carriers and integrators, ensure carrier charges map correctly to internal data, drive rate shadowing to catch mispricing, and partner with Accounting, Strategic Finance, and Analytics to reconcile margin reporting into a single trusted source of truth.
