• Design and implement backup, recovery, and disaster recovery strategies to safeguard data integrity and minimize downtime.
• Plan and execute database upgrades, patches, and migrations with minimal disruption to production systems.
• Troubleshoot and resolve complex database incidents, performing root cause analysis and implementing preventive measures.
• Manage database security, including user access controls, roles, encryption, and compliance with data governance and regulatory requirements.
• Establish and enforce database standards, policies, and best practices across the organization.
• Develop and maintain documentation for database architecture, configurations, standard operating procedures, and runbooks.

• Working knowledge of database security practices — access control, roles, encryption at rest/in transit, and audit/compliance requirements.
• Scripting proficiency in Python, Bash, or PowerShell, with experience automating routine DBA tasks; familiarity with infrastructure-as-code tools (e.g., Terraform, CloudFormation) is a plus.
