Brussels, on site. careersite–jobs–form-overlay#showFormOverlay” data-careersite–jobs–form-overlay-target=”coverButton”> Apply for this job blocks–cover–scroll#handleScrollDown” title=”Scroll to content”> This is a production DBA post on open source engines: PostgreSQL and MySQL, standalone and clustered, across development, test and live. It is the unglamorous half of database work - the half where replication lag, lock contention and a badly planned query decide whether anyone else can do their job today. It suits someone who tunes rather than guesses, who has restored from backup in earnest, and who writes the root cause analysis afterwards because the next incident depends on it. What you would be doing

• Install, configure, maintain and upgrade PostgreSQL 12+ and MySQL 8+, standalone and clustered.
• Run routine maintenance properly - schema housekeeping, index maintenance, statistics, retention.
• Manage users, roles, privileges and authentication on least-privilege lines.
• Forecast storage growth and advise on partitioning and archiving before capacity becomes an incident.
• Troubleshoot production problems: data corruption, replication failures, performance degradation.
• Monitor database health - lock contention, deadlocks, wait events, replication lag, resource use.
• Analyse and optimise query performance, with execution plans and InnoDB tuning as everyday tools.

• Produce root cause analysis for critical incidents and keep environments consistent., Senior Database Engineer (PostgreSQL 12+, MySQL 8+, High Availability) for NATO with security clearance Open source databases in production, run properly - replication that holds, queries that behave, and a root cause for every incident.

• Solid production experience on both PostgreSQL and MySQL.
• Replication, clustering and recovery experience that has been tested rather than documented.
• Real query optimisation practice on both engines.
• Capacity planning and monitoring instincts.
• The habit of coordinating with application and infrastructure teams rather than around them.
