Job Description:

Looking for an experienced QA Analyst with an automotive finance background to validate mainframe upgrades to the Customer Account Servicing System (CASS) through the CAP release (Customer Account Servicing System Application Package Release) process.

CAP bundles together multiple RSECS into a single release for production deployment. The CAP release ensures Compliance with regulatory requirements, Performance and stability of account servicing functions and Integration of customizations and homegrown modules.
