  • Monitor and analyze database performance using tools such as Idera, Query Store, Profiler, or other comparable solutions.
  • Develop and maintain documentation, best practices, and training materials to upskill other DBAs and developers.
  • Support production environments, ensuring availability, scalability, and reliability of mission-critical databases.
  • Participate in on-call rotation for production support.
  • Automate administrative tasks through scripting languages (Python, PowerShell, etc.) or third-party tools.
  • Collaborate with infrastructure, application development, and offshore DBA teams (10+ DBAs globally).
  • Contribute to capacity planning, system upgrades, and future-proofing of database environments.

Qualifications

  • Bachelor’s degree in Computer Science, Information Systems, or related field (or equivalent experience).
  • 10+ years of experience as a SQL Server DBA in large-scale enterprise environments.
  • Proven expertise in SQL performance tuning, optimization, and troubleshooting.
  • Strong understanding of database architecture, indexing strategies, query execution plans, and transaction processing.
  • Hands-on experience with Idera Performance tools (or similar).
  • Experience with installation, upgrades, backup / recovery, and high availability (Always On, clustering, etc.).
  • Ability to lead and mentor other DBAs in performance tuning techniques.
  • Excellent problem-solving, analytical, and communication skills.

    • Preferred Skills

  • Exposure to MySQL, PostgreSQL, Azure SQL, and BigQuery.
  • Experience with automation via Python, PowerShell, or similar scripting tools.
  • Microsoft Certified Database Administrator or other industry certifications.
  • Background in development and DBA roles, offering a hybrid perspective.
  • Experience in high-transaction industries (e.g., finance, ecommerce, telecom).

    • Why Join?

  • Opportunity to step into a leadership path as the team transitions.
