ppThis 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. /ppIt 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. /ph3What you would be doing /h3ulliInstall, configure, maintain and upgrade PostgreSQL 12+ and MySQL 8+, standalone and clustered. /liliRun routine maintenance properly — schema housekeeping, index maintenance, statistics, retention. /liliManage users, roles, privileges and authentication on least-privilege lines. /liliForecast storage growth and advise on partitioning and archiving before capacity becomes an incident. /liliTroubleshoot production problems: data corruption, replication failures, performance degradation. /liliMonitor database health — lock contention, deadlocks, wait events, replication lag, resource use. /liliAnalyse and optimise query performance, with execution plans and InnoDB tuning as everyday tools. /liliProduce root cause analysis for critical incidents and keep environments consistent. /li /ulh3What you would bring /h3ulliSolid production experience on both PostgreSQL and MySQL. /liliReplication, clustering and recovery experience that has been tested rather than documented. /liliReal query optimisation practice on both engines. /liliCapacity planning and monitoring instincts. /liliThe habit of coordinating with application and infrastructure teams rather than around them. /li /ulpThe work is full time on site in Brussels. /p /p
