Core Responsibilities

Primary Functions

Manage the full lifecycle of database systems including installation, configuration, patching, upgrades, and decommissioning across on-premises and cloud platforms to ensure systems remain secure, supported, and performant.
Design, implement, and maintain backup and recovery strategies (including point-in-time recovery and cross-region replication) and conduct regular restore drills to validate disaster recovery plans and meet RTO/RPO targets.
Perform proactive performance tuning and query optimization by analyzing execution plans, indexes, statistics, and schema design to reduce latency and improve throughput for critical business applications.
Monitor database health and capacity using enterprise monitoring tools, set meaningful alerts, and respond to production incidents to minimize downtime and meet service level agreements.
Architect and implement high availability and failover solutions such as clustering, Always On Availability Groups, streaming replication, or cloud-native multi-AZ configurations to provide uninterrupted service.
Implement and maintain secure access controls, role-based permissions, encryption at rest and in transit, and auditing configurations to ensure compliance with internal policies and regulatory standards (e.g., GDPR, HIPAA, SOX).
Lead database migration and data movement projects including schema conversion, ETL coordination, data validation, and cutover planning for migrations to cloud platforms like AWS RDS/Aurora, Azure SQL, or GCP Cloud SQL.
Create, tune, and maintain stored procedures, triggers, functions, and scheduled jobs; ensure code follows best practices and is version-controlled as part of CI/CD pipelines.
Troubleshoot complex production issues by performing root cause analysis, documenting findings, and implementing long-term corrective actions to prevent recurrence.
Implement and manage replication, sharding, partitioning, and other scalability techniques to support large datasets and high-concurrency workloads.
Collaborate with development teams to review database changes, advise on schema design patterns, and participate in architectural design reviews to ensure optimal data models and query efficiency.
Automate repetitive operational tasks using scripting languages (Bash, PowerShell, Python) and configuration management or IaC tools (Ansible, Terraform) to increase reliability and deployment speed.
Maintain and tune database indexes, update statistics, and perform routine maintenance tasks (rebuild/reorganize indexes, update histograms) to sustain performance over time.
Administer and tune NoSQL and caching technologies when applicable (e.g., MongoDB, Redis, Cassandra) to support hybrid data architectures and reduce load on primary relational databases.
Manage license compliance, capacity planning, and cost optimization for commercial and cloud-managed database services to align with budget and governance requirements.
Maintain comprehensive runbooks, architecture diagrams, and operational documentation for on-call rotations, escalation procedures, and change management records.
Evaluate, select, and pilot database-related tools and third-party solutions (monitoring, backup, replication) to improve operational maturity and observability.
Conduct security reviews, vulnerability scans, and patch management to remediate risks and ensure sensitive data is protected according to policy and compliance frameworks.
Participate in incident management and post-incident reviews; provide actionable remediation plans, timeline estimates, and communicate status clearly to stakeholders during major outages.
Mentor and train junior DBAs and application engineers on database best practices, troubleshooting methodologies, and performance optimization techniques.
Define and track operational KPIs such as query response times, backup success rates, replication lag, and system availability to demonstrate improvements and guide capacity decisions.
Support database-related change control processes, including risk assessment, rollback planning, testing, and coordination with application owners and infrastructure teams.
Provide Level 2/3 support for escalated database issues, collaborating with vendors and cloud support as needed to resolve complex product or service defects.

Secondary Functions

Support ad-hoc data requests and exploratory data analysis to assist business users and analytics teams in extracting actionable insights.
Contribute to the organization's data strategy and roadmap by providing technical guidance on database platform choices, scaling strategies, and cloud-first options.
Collaborate with business units to translate data needs into engineering requirements and establish realistic delivery timelines.
Participate in sprint planning and agile ceremonies within the data engineering team to ensure database work is aligned with product priorities.
Assist with cost governance and chargeback reporting for cloud database resources to help optimize spend and resource allocation.
Review and enforce database coding standards and perform peer reviews of SQL and migration scripts to maintain quality and reliability.
Help evaluate data retention, archival, and purging policies to balance compliance, performance, and storage costs.
Integrate database monitoring and logging outputs into centralized observability platforms (e.g., Prometheus/Grafana, Splunk, New Relic) to provide consolidated operational insights.
