About the role

We’re looking for a Senior Database Administrator who owns the data layer that millions of people depend on every day. You’ll be the person who rules our databases, with deep hands-on expertise acrossBigQuery andPostgreSQL on GCP, and the trusted point of contact who helps the rest of engineering work better with data.

The role is part deep expertise and part influence. We run a multi-domain GCP platform with around60 PostgreSQL databases (Cloud SQL, PostgreSQL 17, regional HA) spread across our business domains, plusBigQuery as our analytics warehouse fed byDatastream CDC pipelines. You’ll set the standards, tune slow queries, harden fragile systems, and teach developers to design schemas, queries, and access patterns that scale. As the main bridge between Core Platform and product teams, your job is to make good database practice the norm across the company, and to leave every team more capable with data than it was before.

• Define and champion database standards for schema design, migrations, indexing, connection management, and safe change processes.

• Educate and mentor developers through reviews, pairing, documentation, and internal sessions, leaving teams more self-sufficient with data.

• Own database reliability and correctness: backups, point-in-time recovery, HA and failover, replication, and our us-east1 and us-west1 DR posture.

• Support our data pipelines, keeping the PostgreSQL to BigQuery flow viaDatastream (CDC) healthy across schemas, logical decoding, and replication.

• Drive database security and governance with IAM-based authentication, least privilege, pgAudit, and secrets managed through Secret Manager.

• Improve database operations through automation, working within ourOpenTofu andTerragrunt Infrastructure-as-Code.

• Solid hands-on experience operating databases onGoogle Cloud Platform (GCP), ideallyCloud SQL for PostgreSQL.

• A track record of performance tuning: query plans, indexing strategies, connection pooling, and diagnosing production issues under load.

• Experience with backups, point-in-time recovery, high availability, replication, and disaster recovery.

• A genuine teaching mindset, able to explain complex data concepts clearly and guide developers toward better practices.

• Strong communication and stakeholder skills, comfortable being the bridge between platform and product teams.

• Excellent problem-solving and analytical thinking, with genuine curiosity about new technology.

Desirable skills
