ABOUT THE ROLE

We're hiring an experienced SQL Server Database Developer / DBA on behalf of our client, an Agency of the United Nations in Vienna. You'll join the team that builds and supports enterprise software used by government agencies in UN Member States around the world.

This is a hands-on role covering two areas. Most of it is performance engineering: tuning queries, procedures and indexes. The rest is production DBA work: backups, security, maintenance and database health. You'll also be the go-to database expert when clients run into performance problems.

• Read execution plans and use Extended Events / SQL Server Profiler to find bottlenecks
• Design and implement indexing strategies
• Troubleshoot deadlocks, blocking and other concurrency problems
• Build and maintain ETL and data transformation processes
• Manage backups, user roles, permissions and security policies
• Automate maintenance (index rebuilds, statistics updates, integrity checks) and manage scheduled jobs
• Keep databases consistent and healthy, and fix issues as they come up
• Help clients with root cause analysis when they hit timeouts or slow response times
• Advise on database architecture and performance improvements

WHAT WE'RE LOOKING FOR

• Bachelor's degree in Computer Science, Information Systems or a related field
• 5+ years of hands-on experience developing and programming with Microsoft SQL Server
• 5+ years of progressively responsible experience designing, building and maintaining information systems
• Strong skills in T-SQL, query tuning and diagnosing performance issues
• Experience working in Agile teams
• Fluent English (required)

NICE TO HAVE

• Microsoft TFS / Azure DevOps
• SSIS or other ETL tools
• French or another UN official language

WHY JOIN

• Work for a United Nations agency on systems used by governments worldwide
• An international, multicultural workplace at the UN in Vienna
• A role where your performance tuning has a visible impact
