• Deep MySQL expertise — replication, query tuning, schema optimisation, upgrades, migrations
• Strong experience with database monitoring and performance tools (e.g. Percona, Grafana, Prometheus)
• Solid understanding of Linux environments and networking basics
• Ability to design, implement, and document solutions for high-scale systems
• Great communicator who can partner with engineers, product teams, and stakeholders

Desirable

• Partnerize is scaling - replacing legacy systems, expanding our technical estate, and evolving our platform for the future. Our databases are at the heart of everything, and we’re looking for a Senior Infrastructure Engineer to take MySQL performance, reliability, and scalability to the next level
• While we’d ideally love you to be based in or around Newcastle - popping into the office once a week or month - we know incredible talent doesn’t always look like that. We’re a remote‑first team and open to conversations about how and where you work best
• Lead the design, optimisation, and operation of high-availability MySQL environments
• Optimise query performance, indexing, and schema design to keep our systems fast and efficient
• Manage upgrades, migrations, and replication (multi-master, geo-replication, GTID) with minimal downtime
• Proactively monitor database health and troubleshoot issues before they become critical
• Collaborate with development teams to improve database architecture and support application growth
• Mentor other engineers and set best practices for database operations
