Job Description & How to Apply Below
The Principal Database Administrator will support multiple product teams across Dealer Solutions and play a key role in working on (managed and optimized enterprise database systems) cloud migration initiatives.

This role will be responsible for managing, optimizing, and re-architecting the current on-premises database environment. As a key technical enabler of the organization's cloud strategy, the Senior Database Administrator will first stabilize and remediate the existing database infrastructure, then design and execute a safe, phased migration to AWS.

They are responsible for defining database strategy, driving cloud modernization efforts, advising architects and software engineers on data architecture decisions, ensuring high availability and security of enterprise platforms, and leading complex migration, resiliency, and performance initiatives. They possess deep expertise across both traditional relational databases and modern cloud-native data platforms while influencing technical direction across multiple engineering teams.
