Database Administrator - Microsoft Azure, Public Sector

At Xtremax, we're looking for a Database Administrator (Microsoft SQL Server & Azure) to support enterprise-scale database platforms that power mission-critical digital services within Singapore's public sector.

You'll work on Microsoft SQL Server environments hosted on Singapore's Government on Commercial Cloud (GCC) as part of the Singapore Government Technology Stack (SGTS). From Azure SQL Managed Instance and SQL Server on Azure Virtual Machines to high availability, disaster recovery, database security, and performance optimisation, you'll play a key role in ensuring critical systems remain secure, resilient, and highly available.

Working closely with Cloud Platform Engineers, DevSecOps teams, and application developers, you'll manage the full database lifecycle—from provisioning and migration to monitoring, tuning, backup, recovery, and continuous improvement. This is an excellent opportunity for experienced DBAs looking to deepen their expertise in Azure database technologies within a highly governed cloud environment.

• Implement monitoring, alerting, and auditing using Azure Monitor, Microsoft Defender for SQL, Microsoft Sentinel, and related Azure services.
• Develop and maintain database operational runbooks, technical documentation, and disaster recovery procedures.
• Collaborate with infrastructure, cloud, and application teams to deliver secure, reliable, and highly available database services.

• Degree or Diploma in Computer Science, Information Technology, Software Engineering, or a related discipline.
• At least 5 years of hands-on Microsoft SQL Server Database Administration experience.
• Strong experience managing SQL Server 2016 or later in production environments.

• Hands-on experience with database backup, point-in-time recovery, and disaster recovery testing.
• Good understanding of SQL Server security features including TDE, Dynamic Data Masking, Always Encrypted, auditing, and role-based access control.
• Experience working with Azure Monitor, Azure SQL monitoring, or similar database monitoring platforms.
• Strong troubleshooting, analytical, and problem-solving skills.
