The Role
We're looking for a MySQL Database Administrator to join our Engineering team on an initial three-month contract to take ownership of the database infrastructure that underpins SilverRail's rail distribution platforms. These systems process high volumes of search, booking and ticketing transactions for rail operators, retailers and travellers across the UK, Europe, North America and Australia/APAC, so reliability, performance and data integrity are critical to everything we do.
The role sits within the Platform Engineering function and works closely with engineering, infrastructure and platform teams to design, tune and safeguard the databases behind our products over the course of the contract. You'll report to the Engineering Manager (Database & Infrastructure).
We're looking for an experienced contractor with a solid grounding in MySQL database administration who can get up to speed quickly and work autonomously on schema design, query and database optimisation, and cloud-hosted database infrastructure from day one. We are looking for someone who has supported systems with high transaction volumes and strict availability requirements, such as travel, e-commerce or financial services.
