About The Position

Looking for a Senior Database Administrator (MS SQL & Oracle) to support enterprise application discovery, database assessment, migration planning, and operational modernization. This is a "hands-on expert" role, comfortable with complex database schemas and coordinating migration strategies with client stakeholders. The ideal candidate thrives on technical challenges, such as moving workloads from physical and VMware environments to OpenStack-based private clouds, and possesses a "startup mentality" to adapt to tight migration windows. This role is crucial for ensuring database performance, recovery, and high availability remain robust as clients transition to next-generation infrastructure.

Requirements

• 8+ years of hands-on DBA experience, specifically supporting business-critical databases and working across application and infrastructure teams.
• Strong experience with both Microsoft SQL Server and Oracle Database, including installation, configuration, maintenance, and troubleshooting.
• Strong hands-on experience with SQL Server Always On, failover clustering, replication, and Oracle Data Guard/RMAN.
• Proven experience moving databases from physical or VMware-based environments to private cloud or modern infrastructure platforms.
• Strong ability to troubleshoot performance issues and tune SQL queries, indexes, and execution plans.
• A strategic approach to problem-solving, a startup mentality, and the flexibility to support migration readiness decisions during critical windows.
• Exceptional skills in documenting findings and explaining technical risks to both client and internal stakeholders.

Responsibilities

• Application and Database Discovery: Participate in assessment workshops to document current client applications, database dependencies, schemas, and operational requirements.
• Migration Assessment and Planning: Evaluate architectures hosted on physical servers or VMware and define migration approaches for OpenStack-based private cloud environments.
• MS SQL and Oracle Administration: Administer, monitor, maintain, and troubleshoot enterprise database environments across production and non-production systems.
• Database Restore and Recovery: Perform database restores, recovery validation, and troubleshooting of restore-related issues to support migration and production operations.
• Performance Tuning: Analyze and tune SQL queries, indexes, execution plans, and database configurations to improve application and database performance.
• High Availability and Clustering: Support SQL Server clustering, Always On availability groups, and Oracle Data Guard to ensure robust failover and disaster recovery practices.
• Technical Documentation & Advisory: Document migration risks and operational runbooks while working directly with client teams to explain findings and recommend improvements.
