error rates, and reducing MTTR.

Build and maintain monitoring, alerting, and observability using tools

such as Splunk and New Relic.

Participate in on-call rotations, incident response, root-cause

analysis, and post-incident improvements.

launches) and support change discipline during critical windows.

Ensure data accuracy, auditability, and reconciliation across inventory,

order, and financial systems.

Maintain strong security, access controls, and compliance standards for

systems used in physically accessible store environments.
