£90,000-£95,000 + Bonus + Equity

Our client, a rapidly scaling fintech scale up, is hiring a Senior Database Administrator to support and optimise the SQL Server environments that power their global client base. Customers operate both self-hosted and SaaS deployments, each with different performance profiles, scale requirements, and operational constraints.

This is a hands-on, high-impact role supporting complex financial workloads, large datasets, and auto-generated code that requires careful optimisation, monitoring, and proactive maintenance to ensure reliability, speed, and predictable behaviour at scale.

Key Responsibilities

• Manage and optimise SQL Server instances across SaaS and client-hosted environments.
• Analyse and improve performance of auto-generated queries and ORM-driven SQL.
• Lead indexing, statistics, and query-tuning strategies for high-volume workloads.
• Maintain database hygiene: fragmentation, archiving, growth plans, and maintenance jobs.
• Diagnose client issues, query analysis, and recommend configuration improvements.
• Implement and refine DB monitoring, alerting, and performance baselines.
• Review schema changes and advise Engineering on efficient data access patterns.
• Produce clear guidance for client DB configuration, scaling, and operational practices.
• Support incident response and lead RCAs for database-related issues.

About You - Ideal Profile

• 7+ years as a SQL Server DBA supporting large-scale or enterprise systems.
• Deep expertise in T-SQL, execution plans, indexing, and SQL Server internals.
• Experience with Azure SQL, Managed Instance, VM-hosted, and client-managed installs.
• Strong capability in tuning auto-generated SQL and identifying structural bottlenecks.
• Comfortable working directly with clients to diagnose issues and promote best-practice.
• Experienced with monitoring and observability tools (Azure Monitor, etc.).
• Strong grounding in security, backups, HA/DR, and resilience for mission-critical systems.
• Proactive, analytical, calm under pressure, and highly attentive to detail.

What Success Looks Like (KPIs & Metrics)

• Faster query execution, reduced slow-running operations, and improved throughput.
• Stable, predictable performance across all hosting models.
• Improved index health, lower fragmentation, and consistent database hygiene.
• Positive client feedback on support quality and performance recommendations.
• Fewer DB-related incidents with root cause and preventative measures adopted.
• Engineering alignment to recommended schema, SQL, and operational standards.
