Project Overview

This role supports Capital One s Exceptions One team and collaborates closely with the One Pipeline team. The organization is migrating existing exception data currently consumed from ServiceNow into the Exceptions One platform.

One Pipeline currently reads exception data via ServiceNow APIs. As part of this initiative, the new hire will assist in modifying One Pipeline backend systems to consume the same data from the new Exceptions One API, including schema and contract changes.

This role is purely backend-focused and is best suited for engineers experienced in both Java and Golang, with strong exposure to NoSQL/document databases.

The work includes analyzing existing ServiceNow integrations, understanding the One Pipeline architecture, and implementing updates to adopt the new Exceptions One API.
