About the role

We're looking for a Staff Database Engineer to join our team during an exciting phase of growth. In this role, you'll be responsible for database architecture, database reliability, infrastructure-adjacent database platforms, performance engineering, observability, automation, operational maturity, incident response, and engineering leadership, working closely with cross-functional partners to support business objectives while upholding our standards for excellence, collaboration, and impact.

Responsibilities

• Database Architecture & Platform Ownership
• Define standard database patterns for high availability, replication, failover, backup and restore, point-in-time recovery, performance baselining, capacity planning, upgrade lifecycle management, access control and operational security.
• Establish database design standards for new internal platforms, including schema review, indexing strategy, query design, service ownership boundaries, and production readiness requirements.
• PostgreSQL, MySQL, and Database Reliability
• Operate and improve production database environments across PostgreSQL, MySQL, Percona, and adjacent systems.
• Own the lifecycle of database systems, including provisioning, configuration, version upgrades, replication topology design, performance tuning, backup validation, disaster recovery testing, decommissioning, documentation and runbook creation
• Troubleshoot and resolve production database issues involving query latency, lock contention, replication lag, storage I/O bottlenecks, connection exhaustion, poor indexing, schema design problems, database capacity constraints, backup or restore failures
• Drive root cause analysis for database-related incidents and convert findings into durable engineering improvements.
• Slurm, NetBox, and Infrastructure Data Systems
• Serve as the senior database engineering owner for infrastructure-adjacent database platforms, including Slurm and NetBox.
• For Slurm environments, support and improve database architecture related to SlurmDBD, accounting data, job history, reporting queries, performance and retention strategy, database scaling, backup and recovery, long-term operational reliability
• For NetBox and source-of-truth systems, support PostgreSQL performance, database lifecycle planning, backup and restore validation, data integrity, schema-impact review, integration patterns with automation systems
• Partner with DevOps, Infrastructure, MLOps, and Platform Engineering teams to ensure database-backed systems are designed to scale as the environment grows.
• Performance Engineering & Observability
• Build deep database observability beyond basic dashboards.
• Develop and maintain visibility into query performance, execution plans, index usage, replication health, locking behavior, buffer/cache efficiency, storage latency, connection pool behavior, OS-level database bottlenecks
• Use tools such as PostgreSQL native statistics, MySQL/Percona tooling, Prometheus, Grafana, PMM, Query logs, slow query logs, eBPF/BCC or equivalent low-level profiling tools, Linux performance tooling
• Create performance baselines and alerting standards for critical database platforms.
• Identify recurring database failure patterns and build preventive monitoring, automation, and operational guardrails.
• Automation, Standards, and Operational Maturity
• Create database automation patterns that can be integrated with existing infrastructure tooling.
• Partner with DevOps and Infrastructure Engineering to automate database provisioning, configuration standards, backup verification, health checks, replication checks, user and permission management, upgrade workflows, monitoring deployment, runbook-driven recovery procedures
• Contribute database-specific modules, roles, or workflows to Ansible, CI/CD pipelines, or internal automation platforms where appropriate.
• Define production database readiness standards for new services before they are promoted into critical environments.
• Incident Response & Engineering Leadership
• Act as the technical lead for major database incidents.
• Own or support triage, root cause analysis, cross-team coordination, customer or stakeholder impact analysis, postmortems, corrective action plans, long-term remediation
• Mentor L4
