LATAM WHAT YOU WILL BE DOING

About the

Role:

This role owns a roughly 65TB Microsoft SQL Server estate running in a highly available, clustered configuration, supporting the Insightly CRM product directly. This is production database work for a live, customer-facing SaaS platform, not an analytics or reporting role.

What this role will do:

• Lead maintenance of the production SQL Server environment in an Always On availability group configuration, including failover handling, sync delay troubleshooting, and read replica load management
• Carry 24x7 on-call for SQL alerts, lead incident response and root cause analysis for query plan regressions, TempDB contention, and deadlocks or blocking
• Maintain database security: TDE, auditing, certificate and key rotation, and monitoring for anomalous access patterns
• Run quarterly cumulative update patching across environments, index and statistics maintenance, and partitioning and archiving on multi-terabyte databases without blocking production
• Own capacity planning for storage, CPU, and memory, and manage the recurring cycle of environment refreshes (staging, dev, QA)
• Review developers' T-SQL and schema changes before deployment, and advise on table and index design
• Support customer instance migrations between regions (sold as a service) and database prep for those moves
• Handle confidential or legally sensitive data requests when they arise, including from law enforcement, following established process
• Design and test disaster recovery for the database environment

WHAT WE'RE LOOKING FOR

• 7 years of hands-on Microsoft SQL Server DBA experience in a 24x7 production environment, not SQL development alone
• 3 years of direct experience with Always On availability groups, including failover handling and sync delay troubleshooting
• Experience managing multi-terabyte production databases, including partitioning, archiving, and index and statistics maintenance without blocking production
• Experience leading incident response and root cause analysis for production database issues
• Experience with database security practices: TDE, auditing, certificate and key rotation
• English fluency sufficient for real-time incident communication, with meaningful business hours overlap with Pacific time

WHAT WOULD BE A PLUS?

• Experience supporting a SaaS CRM or similarly high-transaction-volume application
• Exposure to Snowflake, Redshift, or AWS Aurora alongside transactional SQL Server work
• Experience with customer instance migrations or similar large-scale data movement projects
• Experience in a SOC 2, HIPAA, or PCI-regulated environment
• Comfort handling legally sensitive or confidential data requests as part of a defined process
