Database Administrator

We are looking for a talented, energetic, and detail-oriented Mid-Level Database Administrator (DBA) with deep SQL optimization experience to join our growing team. Over the past two years, our organization successfully transitioned from an on-premises datacenter to 100% in the AWS cloud. In this role, you will be part of a geographically dispersed DBA team responsible for managing our fully cloud-native database environment. You will work closely with IT, Engineering, QA, and Data & Analytics teams to modernize, maintain, and improve our data architecture.
A deep understanding of SQL, robust cloud database management skills, and independent problem-solving abilities are essential for this role. While our ecosystem is heavily focused on PostgreSQL, experience maintaining or migrating legacy SQL Server environments is highly valued.
