What You’ll Do: — Keep the Aurora PostgreSQL fleet healthy across all data centers: building indexes on large and partitioned tables without downtime, analyzing plans, and moving data. — Handle Aurora configuration (parameters, replicas, failover, capacity) and cost work: rightsizing, merging low-activity databases, and evaluating serverless. — Take ownership of the PgBouncer layer, which currently needs an owner and a roadmap. — Review schemas and data models with product teams, advising on partitioning, retention, and shared vs. dedicated clusters, backing recommendations with data. — Work on the performance of the main application and the search queries behind AI features, including research toward a 10,000 jobs/second target. — Package the team's existing zero-downtime upgrade and switchover procedures into versioned, released automation, along with provisioning of databases and users, grants, and schema sync across data centers (Terraform, Ansible, GitOps). — Develop and deploy tooling for monitoring and managing the PostgreSQL fleet in Kubernetes, including monitoring and alerting (exporters, VictoriaMetrics). — Handle database incidents end-to-end, including root-cause analysis and follow-up fixes, and participate in resilience projects such as a cross-region DR pilot, application reconnect after failover, and CDC pipelines that survive upgrades and failovers. — Contribute to time-boxed evaluations of new database technologies that end with a decision on adoption. — Participate in the on-call rotation, with off-rotation time dedicated to uninterrupted project work. What You Have: — 5+ years of experience operating PostgreSQL in production (DBA, DBRE, or SRE with a database focus) on databases under real load. — Deep experience with database schemas: design, debugging, and troubleshooting performance issues in production. — SQL proficiency, query plans, indexing strategy, and performance work on multi-TB tables. — Expertise in the PostgreSQL ecosystem: streaming and logical replication, HA and failover setups (Patroni or equivalent), connection poolers (PgBouncer), major-version upgrades and migrations with minimal downtime. — Linux fundamentals: processes and memory, OOM behavior, networking basics. — Scripting skills (Bash, Python, or Go) and an automation-first attitude. — Readiness to work actively with Kubernetes. — Strong root cause analysis and incident management skills. — Good level of English — at least Upper-intermediate (B2). Nice-to-Haves: — Experience with Infrastructure as Code (Terraform) and cloud infrastructure (AWS, ideally hands-on Aurora or RDS). — Experience with different storage systems: ClickHouse, OpenSearch, Elasticsearch, Redis, Valkey, MemoryDB, Neo4j. — Exposure to Kubernetes basics, GitOps, ArgoCD, or Vault. — Contributions to open-source database or infrastructure projects. — Openness to using AI assistants in daily work.
