Resume tips for this job
- List databases by platform and size: managers want to see you've handled enterprise-scale systems, not just small single-server setups
- Always include uptime percentage or SLA achievements; these numbers prove your database stays running when business depends on it
- Name specific tools: SQL Server, Oracle, MongoDB, or AWS RDS matter more than generic database experience
Common questions
Should I list every database I touched or just the major platforms?
Focus on platforms where you have deep expertise and measurable impact. Listing 10 minor databases waters down your resume. Group similar platforms and lead with results: instead of listing 40 databases, say '40+ enterprise databases across SQL Server 2019 and Oracle 19c.'
How do I explain gaps between backup windows or maintenance projects?
Don't. Recruiters understand database work involves routine maintenance, on-call coverage, and downtime windows. Stick to accomplishments and systems you owned. If you changed roles or companies, explain that transition clearly with start/end dates.
