Senior Database Reliability Engineer for the Infrastructure Platform Team to design PostgreSQL platforms for resilience and high availability, automate database infrastructure, and maintain latency within SLO at reasonable cost.

Responsibilities

Design and run highly available PostgreSQL across zones and regions, with automated, tested failover and fencing against split-brain.
Define all database infrastructure as code (clusters, parameters, networking, access, monitoring and backups), reviewed by peers and applied through CI/CD pipelines, with drift detection.
Build self-service database provisioning so product teams get a production-ready database without waiting on a ticket.
Plan and execute migrations, upgrades and table moves with zero or near zero downtime, including cross-version, cross-cluster and cross-cloud work.
Partner with developers on schema changes, queries, connection pooling, transaction scope, retries and expand-and-contract migrations, so database issues are fixed at their source.
