Staff Database Reliability Engineer (DBRE)

Role overview

Improve the reliability, performance, and capacity of production database systems that support a large-scale security platform. As a staff-level database reliability engineer, you will manage PostgreSQL infrastructure, anticipate growth needs, and work with site reliability and application engineers to keep services responsive and resilient in a 24/7 environment.

Responsibilities

- Tune PostgreSQL configuration to match workload demands and make effective use of available resources. - Forecast capacity needs from application growth and usage patterns, then recommend scaling approaches. - Build monitoring dashboards and alerts for database health, including latency, throughput, connections, and cache performance. - Design and maintain indexing strategies, removing redundant or low-value indexes that affect write performance. - Apply partitioning and, where needed, coordinate database sharding for large data sets. - Optimize cloud database deployments in partnership with site reliability engineers, and advise application teams on query, schema, and index design.

Requirements

- Five or more years managing, configuring, maintaining, and scaling PostgreSQL clusters in production. - Deep knowledge of PostgreSQL internals, including write-ahead logging, transactions, locking, and background processes such as autovacuum. - Hands-on experience with large, high-transaction or terabyte-scale databases in live, 24/7 production environments. - Expertise in replication, failover, and dependable backup and recovery strategies. - Strong practical experience tuning database performance and using observability tools.

Nice to have

- Familiarity with NoSQL data models and how to choose between relational and non-relational databases for different access patterns. - Experience with infrastructure as code.

Benefits and work setup

- Fully remote work, paid time off and holidays, and 12 weeks of paid parental leave. - Medical, dental, vision, life, and disability coverage; retirement contributions; and stock options for full-time employees. - Home-office and monthly digital reimbursements, plus annual professional-development support and access to coaching.
