Senior Database Engineer (SQL Server Performance Specialist)

About the role

A new Senior Database Engineer role is open, fully remote, for a 12+ month contract. The position brings dedicated SQL Server performance expertise to the engineering team and is not a traditional DBA role: there is no focus on backups, patching or infrastructure. You will work directly with software engineers to diagnose and fix database-driven performance problems in their products.

Key responsibilities

• Detect and resolve SQL Server performance issues in production and pre-production environments
• Analyze, rewrite and optimize complex SQL queries and stored procedures
• Read and interpret execution plans to find bottlenecks and inefficiencies
• Design and refine indexing strategies to improve query performance
• Find and resolve concurrency issues such as blocking, deadlocks and locking contention
• Work with software engineering teams on data access patterns, query design and schema decisions
• Share database performance best practices and build expertise across the team

Required profile

• 6+ years of hands-on experience with SQL Server, with a strong focus on performance tuning
• Proven experience designing and tuning indexing strategies
• Track record of troubleshooting and resolving production database performance issues
• Experience working directly with application development teams, not only in an operations/DBA role
• Citizen of the country of employment or authorized to work there

Required skills

• Expert ability to analyze and optimize complex T-SQL queries
• Deep understanding of execution plans, statistics and the query optimizer
• Strong knowledge of concurrency, isolation levels, locking and blocking
• Nice to have: PostgreSQL, Cassandra or other NoSQL databases, and knowledge of how application code (e.g. Java/ORM frameworks) affects database performance

What we offer

• Flexible remote and hybrid work opportunities
• Continuous learning and professional development programs
• A multicultural workplace with a culture that prioritizes employee wellbeing
