• Advanced T-SQL, including query optimisation and understanding of the SQL Server query optimiser.
• Excellent knowledge of execution plans, indexing, statistics and performance tuning.

• Strong understanding of Entity Framework and how application code generates SQL queries.
• Experience proactively monitoring and diagnosing database performance issues.
• Commercial experience with SQL Server in AWS environments, ideally EC2 and/or RDS.
• Understanding of AWS infrastructure, storage and networking considerations affecting database performance.
• Experience with database backup and recovery, high availability and disaster recovery.
• Familiarity with Always On Availability Groups and/or AWS Multi-AZ configurations.
• Experience planning for database scalability and growing data volumes.
• Scripting skills using PowerShell, dbatools or similar tools.
• Strong analytical and problem-solving skills.
• Excellent communication skills and the ability to work closely with software developers.
• A proactive approach, with the ability to work independently, prioritise issues and drive improvements through to completion.

You'll be comfortable working directly with developers, challenging inefficient queries or application designs where necessary, and explaining technical findings clearly to both technical and non-technical stakeholders. You'll enjoy having ownership, taking the initiative and making a tangible difference to the reliability and performance of business-critical systems.

• £60,000-£65,000 salary, depending on experience.
