I'm currently working with a leading technology organisation who are looking for an experienced Database Administrator to join their team.

This is a great opportunity for either a PostgreSQL DBA with strong Oracle experience, or an Oracle DBA with recent and meaningful PostgreSQL DBA experience.

You will need strong hands-on experience across both technologies, with the ability to confidently talk through your experience during a technical interview.

THE ROLE

You'll take ownership of the application database environment across multiple cloud and on-premise environments, working closely with developers, data pipeline engineers, data scientists and infrastructure teams.

Key responsibilities include:

Managing PostgreSQL database clusters across multiple environments
Monitoring, tuning and optimising PostgreSQL database performance
Hands-on administration and maintenance of Oracle 19c or 21c
Managing data migrations between database instances, including offline environments
Owning data models and the lifecycle of data within the database
Designing, creating and managing schemas, tables and views
Performance optimisation including index tuning, execution plan analysis, query optimisation and partitioning
Managing database clusters and failover strategies
Defining and implementing backup and recovery strategies
Managing database security, roles, permissions and RLS controls
Working with infrastructure teams on database installation and patching
Working with data pipeline engineers and data scientists to ingest a wide range of data sources
Applying best practices for storing JSON objects within PostgreSQL

WHAT WE'RE LOOKING FOR

Strong hands-on DBA experience across PostgreSQL and Oracle
Recent and meaningful PostgreSQL DBA experience - this must go beyond basic exposure, installation or support-level knowledge
Strong hands-on experience with Oracle 19c or 21c
Experience with PostgreSQL performance optimisation, including index tuning, execution plan analysis, query optimisation, sharding and partitioning
Experience managing database clusters and failover
Strong data modelling experience
Experience working closely with development and infrastructure teams
Experience with PostgreSQL extensions such as pgvector, PostGIS or AGE would be beneficial
Additional MSSQL experience would be useful
Single British Nationality
SC clearance as a minimum, with DV targeted
Ability to meet the required UK residency criteria for security clearance

Please ensure your CV clearly outlines your hands-on responsibilities and experience with Oracle 19c/21c and PostgreSQL, as candidates will need to demonstrate their experience across both technologies during the technical interview.
