Job Description
We are looking for a senior SQL Server DBA to join our General Cloud DBA team in Portugal. You will own the day-to-day operation, availability and performance of MSSQL estates hosted on Azure and AWS for GDPR, EMEA and US customers, working a fixed shift aligned to EMEA business hours with rotational on-call responsibility for critical incidents outside those hours. You will also build working capability on Oracle, PostgreSQL and MySQL as secondary platforms to widen cross-platform coverage.

Location:
Spain, Madrid Job Requirements
* 6–10 years of hands-on database administration experience, with a majority on Microsoft SQL Server in production environments.
* Demonstrable experience supporting enterprise or managed-services customers under formal SLAs.
* Bachelor's degree in Computer Science, Information Technology or equivalent practical experience.
* Certifications such as Microsoft Azure Database Administrator Associate (DP-300), Azure Fundamentals (AZ-900) or AWS Certified Database — Specialty are an advantage.
* Eligibility to work in Spain. Professional skills
* Strong written and spoken English; able to communicate directly with customer stakeholders.
* Structured troubleshooting under production pressure, with clear escalation and hand-over discipline across shifts.
* Ownership mindset — validating changes before they reach production and owning the rollback path.




* Willingness to cross-skill into the secondary database platforms; the team actively runs MSSQL Oracle cross-training to widen coverage across the on-call rotation.
* Documentation habit — runbooks, knowledge-base articles and post-incident notes. Job Responsibilities
* 24×7 production support for MSSQL estates across EMEA, GDPR and US customers — incident response, root-cause analysis and SLA-bound resolution of P1/P2 issues.
* Execution and validation of customer scripts and datafixes against production and pre-production databases, including impact assessment, backup/snapshot before execution and ownership of the rollback path.
* Backup, restore and recovery operations; periodic recovery testing and RTO/RPO validation.
* Database refresh, clone and copy activities across environments, including masked refreshes for non-production.
* High availability and disaster recovery: configuration, monitoring, failover testing and recovery.
* Performance monitoring and tuning — query and index optimisation, blocking and contention analysis, capacity and growth management.
* Planned change delivery: pre-implementation backups, implementation, post-implementation and post-patching validation within agreed maintenance windows.
* Access and permission management, user provisioning and privilege reviews.
* Patching, upgrades and migrations, including cloud migrations and version upgrades.
* Automation of routine operational tasks and contribution to self-healing and monitoring improvements.
* Proactive analysis of recurring incidents to identify and eliminate root causes rather than repeatedly remediating them.
