Vacancy Details

Employer: PERFORMABILITY RECRUITMENT

About the Role

We are recruiting an experienced SQL Developer to join a collaborative technical team responsible for maintaining and enhancing business‑critical transactional systems.

This role is suited to someone who enjoys hands‑on T‑SQL development and working directly within large, established SQL Server databases. The focus is on database logic, performance, and stability — not analytics, dashboards, or BI tooling.

You’ll be working primarily within the database layer, supporting and improving existing functionality, troubleshooting production issues, and ensuring reliable performance in a live environment.

Key Responsibilities

Develop, maintain, and enhance T‑SQL stored procedures, views, and functions
Work confidently within large, legacy SQL Server codebases
Investigate and resolve production database issues and data anomalies
Analyse and improve query and stored procedure performance
Review execution plans and implement appropriate indexing strategies
Safely enhance existing database logic while maintaining data integrity and system stability
Support database‑driven business processes in transactional systems
Collaborate with internal teams to understand requirements and translate them into effective SQL solutions
Document changes and contribute to ongoing system improvement

Required Skills

Sql: 5 to 6 years
Stored Procedures: 5 to 6 years
T-Sql: 5 to 6 years

Candidate Requirements

What We’re Looking For

5+ years’ hands‑on SQL Server / T‑SQL development experience
Strong experience writing and maintaining complex stored procedures and database logic
Solid understanding of relational database principles, transactions, and constraints
Proven experience with SQL performance tuning and optimisation
Comfortable troubleshooting issues where the root cause is not immediately obvious
Experience working in transactional systems rather than purely analytical environments
Ability to work confidently on existing or legacy systems
Related degree is advantageous, but relevant, practical SQL experience is key.

Advantageous Experience

Exposure to financial, accounting, investment, or fund administration systems
Experience in client‑facing or consulting environments
Exposure to SQL Server Integration Services (SSIS)
Working with high‑volume transactional databases
