About the Role

As a Senior SQL Database Administrator, you will lead the design, deployment, and operational excellence of SQL Server platforms spanning on-premises and cloud infrastructures.

Key Responsibilities

  • Manage the full lifecycle of SQL Server instances, from provisioning and patching to upgrades and decommissioning
  • Design and maintain highly available architectures using Failover Clustering, Always On Availability Groups, and standalone instances
  • Develop and enforce automation-first practices using PowerShell, T-SQL, and CI/CD pipelines (Azure DevOps, GitHub Actions)
  • Implement Infrastructure-as-Code with ARM, Bicep, or Terraform to standardize and streamline deployment
  • Automate routine operations including backups, restores, monitoring, alerting, and disaster recovery testing
  • Drive performance optimization through query tuning, index strategy, and analysis of execution plans and wait statistics
  • Proactively identify capacity constraints and performance bottlenecks, implementing solutions before impact occurs
  • Enforce security standards including encryption (TDE, TLS, Always Encrypted), auditing, and least-privilege access models
  • Support compliance with SOX, ISO 27001, and internal policies through robust logging and configuration controls
  • Operate and optimize SQL workloads in Azure, including Azure SQL Managed Instance, Azure SQL DB, and SQL Server on IaaS VMs
  • Collaborate with engineering teams to guide database architecture and support cloud migration initiatives
  • Mentor junior DBAs and contribute to internal standards, documentation, and design reviews

What You Bring

  • Proven experience as a Senior SQL Server DBA in production environments with deep knowledge of SQL Server internals and T-SQL
  • Strong scripting skills, particularly in PowerShell, and experience integrating database changes into CI/CD pipelines
  • Solid understanding of Windows Server and underlying system infrastructure
  • Track record in managing high-availability and disaster-recovery solutions at scale
  • Familiarity with Azure SQL platforms and Infrastructure-as-Code tools such as Terraform, ARM, or Bicep
  • Exposure to DevOps or Site Reliability Engineering practices in data environments
  • Experience with monitoring solutions like Azure Monitor, SQL Sentry, Redgate, or Prometheus

Work Environment & Benefits

This role operates in a hybrid model with locations in the US and Bermuda, offering flexibility and balance. Benefits include a matching 401K, comprehensive medical, dental, and vision coverage, generous paid time off, parental leave, and support for ongoing professional growth. Additional perks include a gym subsidy and dedicated personal days for wellness, volunteering, or personal interests.
