Senior Database Reliability Engineer

NinjaOne automates endpoint management to provide visibility, security, and control for organizations managing endpoints and servers. The Senior Database Reliability Engineer will own the reliability, performance, architecture, and lifecycle of the company’s database estate across multiple technologies, while partnering on data-related architectural decisions. The role also focuses on improving database tooling, provisioning, developer experience, automation, migrations, and operational health.

Responsibilities:

• Own architectural and lifecycle decisions for the data domain — technology selection, deprecation, capacity planning, and long-term platform direction — as a standing collaborator with Architecture, not an implementer brought in after decisions are made
• Design, operate, and evolve database platforms across multiple technologies: relational, or equivalent time-series stores and data warehouse systems
• Partner with Architecture and Engineering on product and feature decisions that touch data — schema design, access patterns, scalability tradeoffs — early in the design process
• Debug and resolve environment and developer-experience issues across database tooling, provisioning, and local/CI data infrastructure — reduce friction for engineering teams working with data
• Collaborate with Architecture on expanding the technology footprint of the data platform — evaluating and onboarding new database and storage technologies as product needs evolve
• Maintain overall health of database environments: performance, availability, disaster recovery, backup/retention, and security controls across the estate
• Optimize performance, indexing, query plans, and storage/compute configuration across heterogeneous data stores
• Automate provisioning, backup, and lifecycle management; integrate database changes into CI/CD
• Lead migrations, version upgrades, and technology transitions with minimal disruption
• Maintain audit logs, schema versioning, and change tracking for regulatory traceability (SOC 2, FedRAMP, HIPAA as applicable)
• Document architecture decisions, operational runbooks, and platform standards for both technical and non-technical audiences

Requirements:

• 8+ years in database engineering/administration, including 3+ years operating more than one database technology in production
• Demonstrated experience influencing architecture or product decisions involving data — not solely operating systems designed by others
• Deep expertise in at least one relational engine plus working fluency in NoSQL caching
• Experience with time-series data stores and data warehouse platforms (Redshift, Snowflake, BigQuery, or similar)
• Strong cloud-native experience (AWS preferred) — RDS/Aurora, managed NoSQL, IAM, encryption, networking for data services
• Proficiency in scripting/automation and infrastructure-as-code (Terraform, CloudFormation)
• Track record of debugging developer-facing environment issues, not just production incidents
• Strong troubleshooting using logs, metrics, and query analysis across varied storage engines
• Excellent written and verbal communication — able to represent the data domain in cross-functional architecture discussions
• This position is NOT eligible for Visa sponsorship
• Experience with containerized/orchestrated database deployments (Kubernetes, Fargate)
• Cross-cloud data platform experience (GCP, Azure)
• Exposure to distributed systems and data partitioning strategies at scale
• Prior role explicitly scoped as "data platform engineer," "database reliability engineer," or similar hybrid title (vs. pure DBA)
• Experience building or maintaining internal developer tooling/self-service around data infrastructure
