About the Role We are looking for a Senior Database Engineer / DBA to own a large, multi-terabyte Microsoft SQL Server estate running in a highly available, clustered configuration. This is production database work for a live, customer-facing SaaS platform — not an analytics or reporting role. Key Responsibilities - 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. - Provide on-call coverage for SQL alerts and 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, including database preparation for those moves. - Handle confidential or legally sensitive data requests when they arise, following established process. - Design and test disaster recovery for the database environment. - Be available for on-call, weekend maintenance, and other off-hours work as production requires. Must-Have Requirements - 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. Nice to Have - 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. What We're Looking For Beyond Skills - Treats a multi-terabyte production database the way a surgeon treats an operating table — careful, deliberate, and able to stay calm when something is actively on fire. - High ownership and a methodical approach to root cause analysis and preventing repeat incidents. - Clear, composed communication during live incidents and with developers and stakeholders. - Strong discipline around change control, documentation, and data confidentiality. *If you take pride in keeping a large production database fast, secure, and available — even at* *2am — we'd love to hear from you.*
