Job 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

Requirements

Deep, hands-on MongoDB: replica sets, sharding, index and query optimisation, upgrades, and backup and DR you have built and tested yourself
Strong Percona and MySQL: Percona Server, XtraDB Cluster or MySQL at production scale, including replication topology and operational ownership
Solid AWS: running databases on AWS, including RDS and Aurora, plus networking, IAM, storage and monitoring
Genuine Terraform depth: modules you have authored and maintained, state management, deployment pipelines
5+ years hands-on database administration in production
Strong communication. This is a customer-facing, Embedded role

Highly desirable: Experience running database estates in finance, payments, trading, gambling or telecoms, or another environment where downtime is immediately visible and expensive. Aviation, aerospace or safety-critical experience equally welcome. Consulting or customer-facing background is valued.

Not suitable for: Data Engineer, BI Developer or Data Scientist backgrounds. This is hands-on database operations. Candidates without Terraform or AWS experience cannot be considered.
