Large Sharded Databases | High‑Scale SaaS Platform

I’m supporting a growing UK health‑tech organisation that is scaling a next‑generation clinical platform into a fully modern SaaS solution used 24/7 across the NHS. They are looking for a Senior MySQL DBA who loves solving performance challenges at scale and has deep experience working with large sharded MySQL environments.

If you’re a MySQL DBA who gets excited about high‑volume, high‑availability systems this is a role where your technical expertise genuinely makes a difference.

The core requirement (what really matters)

This role is all about two things:
✅ Expert‑level MySQL experience
tuning, replication, scaling, performance engineering.
✅ Hands‑on experience managing large sharded databases
understanding shard allocation, scatter/gather queries, and distributed performance.
If you bring those two skills, you’ll be a standout candidate.
Everything else is a bonus.

What you’ll be doing

Owning the performance and reliability of large sharded MySQL databases in production.
Monitoring shard allocation, query behaviour, MySQL replication and overall DB health.
Ensuring high availability through zero‑downtime patching and robust DR processes.
Overseeing Prometheus/Grafana monitoring, alerting and dashboard optimisation.
Supporting data migrations, including PMI and patient data into the SaaS environment.
Providing performance insights across release cycles and improving infrastructure efficiency.
Acting as the senior MySQL DBA voice within a highly technical engineering team.
What you need to bring
Must have (core):

Strong background as a MySQL DBA.
Real‑world experience working with sharded MySQL databases.
Solid MySQL tuning and replication knowledge.
Experience working within Linux environments.
Good understanding of monitoring (Prometheus/Grafana).
Nice to have (not essential):

Vitess familiarity
Kubernetes, Terraform, Helm or ArgoCD experience
Elasticsearch or Graylog exposure

These are all plus points, not prerequisites.

Who this suits

A MySQL DBA who wants to work with serious scale, distributed systems and a modern engineering stack while contributing to technology that directly supports frontline healthcare
