What is a Database Engineer?
A database engineer specialises in the systems that store a company's data. The work covers schema design, query performance, replication and backups, and making sure the database keeps up as usage grows. When a product slows down, the answer is frequently in the database, and knowing how to find and fix it is a deep, durable skill.
What do they build?
- Schema designs that survive growth
- Query and index optimisation
- Replication and high-availability setups
- Backup and recovery procedures
- Migration plans for live systems

What might be challenging
Worth knowing before you commit. Every path has these.
- Mistakes can mean data loss, so the stakes are high
- Migrations on live systems are stressful
- The role often expects prior backend experience
- Performance work needs real production data to be meaningful
- It is a narrower job market than general backend
