Overview

The Senior SQL Server / MongoDB Database Administrator (DBA) is a senior-level technical and administrative role responsible for managing large-scale, mission-critical database environments. The role will have a primary focus on Microsoft SQL Server and a secondary focus on MongoDB, with responsibilities spanning environment builds, capacity planning, installations, configurations, high availability setup, performance tuning, and proactive monitoring.

The DBA will also act as a consultant to development teams, ensuring database-aware design, efficient coding practices, and system reliability. A strong emphasis is placed on automation (via PowerShell, scripting, and configuration management) to improve consistency, scalability, and operational efficiency.

While the primary focus is on SQL Server and MongoDB, experience with Oracle or cloud-native database technologies (AWS, Azure, GCP, OCI or Atlas) is a plus.
