• Monitoring, maintaining, and troubleshooting database performance, availability, and reliability.


• Supporting database maintenance, upgrades, backups, and recovery activities.


• Contributing to operational projects and continuous improvement initiatives.


• Working closely with Senior DBAs, infrastructure teams, and application teams to support critical production environments.


• Participating in an on-call roster to provide after-hours support for business-critical systems.

• 3-5 years' experience in database administration, although we welcome strong candidates with 2-3 years of relevant experience.


• Strong Oracle Database Administration experience.


• Exposure to Microsoft SQL Server administration.


• Experience supporting large-scale, highly available production environments.


• Knowledge of database operations, maintenance, monitoring, performance tuning, and troubleshooting.


• Strong SQL scripting and problem-solving skills.


• Understanding of backup, recovery, high availability, and disaster recovery principles.


• Ability to participate in a rostered on-call support rotation (approximately every two weeks).


• Flexibility to undertake occasional paid overtime when required.

You’ll stand out from the crowd if you have:

• Experience with PostgreSQL, MySQL, Oracle Exadata, or SQL Server Always On technologies.
