## Description

We are recruiting a Database Reliability Engineer to embed with a leading aviation operator, taking ownership of reliability, performance and observability across their production database estate.
This is deep, hands-on engineering. You will be the accountable engineer for the estate, not a ticket handler and not an advisor.

The environment: MongoDB is the primary technology, with Percona and MySQL as a genuine second pillar and PostgreSQL also in scope. Everything runs on AWS and is provisioned and managed through Terraform.

What you will own:

 * Reliability and availability across the MongoDB and SQL estate
 * Performance tuning: query analysis, index strategy, schema review, scaling decisions
 * Backup, recovery and disaster recovery, designed and actively tested against defined objectives
 * Observability and alerting using Prometheus, Grafana, PMM or equivalent
 * Incident response and root cause analysis
 * Infrastructure automation in Terraform
