A day in the life

- Collaborate with Engineering Science and Product teams to design and implement new capacity tracking features owning the technical architecture from high-level design through deployment testing and including data pipeline construction for capacity ingestion and consumption.
- Design build and maintain scalable backend services and APIs that power the end-to-end lifecycle of capacity tracking: from initial configuration by resource owners through real-time consumption tracking to detection and risk notification ensuring low latency high availability and data accuracy.
- Own and improve systems that detect discrepancies between expected and actual capacity utilization across outbound resources (sort centers delivery stations fulfillment centers) building automated alerting self-healing mechanisms and diagnostic tooling to surface and resolve mismatches proactively using generative AI.
- Partner with capacity resource owners and FO decision-system teams to translate new data requirements and into technical specifications leading design reviews and driving implementation across the service stack.
- Investigate and resolve production issues by performing root-cause analysis authoring corrections of errors (COEs) and driving operational improvements to prevent recurrence.
- Ensure peak event readiness (Prime Day holiday season) by conducting performance and load testing identifying and mitigating system bottlenecks hardening capacity data services for throughput spikes and participating in operational readiness reviews (ORRs) to guarantee timely and accurate risk signals at scale.

About the team
