Role Summary:

The Senior Database Engineer is Medical Guardian's primary owner and steward of the enterprise database platform, accountable for the availability, performance, recoverability, security, and operational health of the organization's data infrastructure, including Microsoft SQL Server, Azure Cosmos DB, and future database technologies.

As Medical Guardian's dedicated database subject matter expert, this individual owns database administration, performance optimization, backup and recovery, disaster recovery readiness, operational automation, database security, and incident response for critical data systems supporting members, caregivers, internal operations, applications, analytics, and emerging technology initiatives, including Medical Guardian's Nexus platform migration and ongoing data platform consolidation across Azure Data Warehouse, Azure Data Lake, Databricks, and Salesforce Data Cloud.

This role works closely with the Data Operations, AI/ML, and Infrastructure teams, providing database expertise and engineering support across initiatives that depend on Medical Guardian's enterprise data platforms. It also partners with Security, Compliance, and Architecture to ensure database services remain resilient, scalable, recoverable, secure, and operationally sound.

This is a dedicated database engineering role. Database availability, security, integrity, performance, and recoverability are the sole primary accountability of this position.

Key Responsibilities:

Database Administration and Platform Ownership

• Serve as Medical Guardian's primary database subject matter expert and technical owner for enterprise database platforms.
• Establish and maintain database operational standards, governance practices, maintenance procedures, lifecycle management processes, and engineering best practices.
• Own the strategic roadmap for database platforms, including modernization, upgrades, migrations, and cloud adoption, including database components of the Nexus transformation.
• Administer and support Microsoft SQL Server across production, development, testing, and disaster recovery environments, and Azure Cosmos DB and future cloud-native database technologies as the platform footprint evolves.
• Manage database installations, upgrades, patching, migrations, configuration management, and version control.
• Maintain database maintenance schedules including backups, integrity checks, index maintenance, statistics updates, and patch management.
• Provide technical guidance to Engineering, Data Operations, AI/ML, Infrastructure, and Architecture on database design, scalability, performance, security, and operational readiness.
• Evaluate emerging database technologies, tools, and operating practices against business and technical objectives.

Performance, Reliability, and Capacity

• Monitor, analyze, and continuously improve database performance across business-critical applications and services, including index strategy, execution plans, blocking, deadlocks, and resource utilization.
• Partner with Engineering, Data Operations, and AI/ML teams to optimize application data-access patterns, SQL performance, data models, and analytics/AI workloads.
• Develop performance baselines, conduct proactive assessments, and remediate issues before they affect production.
• Build and maintain observability, including dashboards, alerting, health checks, and operational reporting, for database availability, health, and capacity.
• Manage database file structures, filegroups, partitioning, and storage growth; forecast capacity requirements and remediate constraints ahead of impact.
• Identify recurring operational issues and implement sustainable engineering fixes rather than manual workarounds.

Backup, Recovery, and Business Continuity

• Own enterprise database backup, retention, restoration, and recovery strategy across supported platforms.
• Define and maintain Recovery Point Objectives (RPO) and Recovery Time Objectives (RTO) in partnership with Technology leadership, and report status against these targets on a defined cadence.
• Execute and document routine backup restoration testing to verify integrity and recovery readiness, retaining evidence for audit purposes.
• Partner with Infrastructure on disaster recovery architecture, failover processes, and resiliency planning; support DR exercises and business continuity events.

Incident Response and Operational Readiness

• Serve as the primary database subject matter expert in Technology's incident response process, including availability, performance, integrity, replication, and recovery events.
• Participate in an on-call rotation and provide after-hours support for critical database incidents.
• Coordinate with Engineering, Data Operations, AI/ML, Infrastructure, Security, and vendors during active incidents to restore service safely and quickly.
• Maintain recovery runbooks, DR procedures, and incident response documentation; lead root cause analysis and drive corrective action.
• Coordinate with Microsoft and other technology vendors during escalated incidents and platform outages.

Automation and Database Engineering

• Automate repetitive database administration and operational activities to improve reliability and reduce manual effort.
• Develop scripts, tooling, and workflows supporting provisioning, maintenance, monitoring, recovery, deployment, and operational reporting (PowerShell, T-SQL, Python).
• Collaborate with Engineering and Infrastructure on database deployment automation, CI/CD, and release validation, and support Infrastructure-as-Code initiatives where they intersect with database platforms.
• Maintain database automation code using source control, peer review, and testing practices consistent with Engineering standards.
• Use AI-assisted engineering tools to accelerate troubleshooting, analysis, documentation, and administration, applying appropriate judgment and validation.

Security, Compliance, and Data Protection

• Implement and maintain database security controls, including permissions, encryption, auditing, access governance, and data protection, in alignment with MG-SEC-DC-001 and applicable data classification requirements.
• Partner with Security and Compliance to support HIPAA, SOC 2 Type II, PCI-DSS, and HITRUST i1 obligations specific to database platforms, including control mapping and evidence collection for audits.
• Monitor and remediate database vulnerabilities within established risk and remediation timelines.
• Ensure database environments maintain logging, monitoring, auditing, and evidence retention sufficient for compliance assessments.
• Apply least-privilege and secure-configuration principles to all database and automation solutions.

Knowledge Continuity and Cross-Training

• Maintain current, accessible runbooks and architecture documentation sufficient for another qualified engineer to operate and recover database platforms in this individual's absence.
• Partner with Infrastructure and Engineering leadership to build secondary coverage (cross-training or a designated backup) for on-call and disaster recovery response.
• Conduct periodic knowledge-transfer sessions with Infrastructure and Engineering to reduce concentration risk on a single individual.

Cross-Functional Collaboration

• Work closely with Data Operations to support data availability, movement, reporting/analytics needs, and reliable access to enterprise data platforms.
• Partner with the AI/ML team on database architecture, data access, performance, and data pipeline requirements for AI/ML solutions, and support ongoing efforts to reduce duplication across the Salesforce Data Cloud and Azure AI/data backend.
• Collaborate with Infrastructure on hosting, compute, storage, networking, high availability, DR, monitoring, and capacity planning.
• Collaborate with Architecture on database strategy, modernization, technical standards, and platform roadmap, including Nexus.
• Support onboarding of new applications, data solutions, integrations, and AI/ML capabilities by ensuring database requirements are scalable, secure, performant, recoverable, and operationally supportable.
