Database reliability engineer for the Rubrik Security Cloud platform in Bengaluru: keeping the PostgreSQL, MySQL and ClickHouse fleets behind a cyber-resilience product fast and recoverable.

This Bengaluru role was posted on 1 September 2026. The platform stores protection data for large enterprises, and this team owns its production database infrastructure: performance, query optimization, disaster recovery and data integrity across both row-oriented and columnar engines. The listing asks for 4+ years running production databases with deep PostgreSQL or MySQL expertise plus hands-on ClickHouse administration.

The role in plain terms

The work spans the full database reliability surface: diagnosing latency regressions, lock contention, index strategy and memory or disk bottlenecks; enforcing RTO/RPO targets with automated backup validation and point-in-time recovery; and operating ClickHouse clusters - topologies, Keeper coordination, the MergeTree engine family. It is a rare role where OLTP and analytical stores meet in one job.

What the employer asks for

These requirements are quoted from the employer's listing, kept in their exact words so eligibility details are not distorted:

4+ years running production database infrastructure, with deep expertise in PostgreSQL or MySQL.
Hands-on administration and performance tuning of ClickHouse (cluster topologies, ZooKeeper/Keeper coordination, MergeTree engine family, mutations, and parts management).

Who this role suits

Database engineers with 4+ years who have run both relational and columnar stores in production - the ClickHouse requirement is explicit, so pure PostgreSQL DBAs without analytical-store experience will struggle. Strong fit for SRE-leaning DBAs who automate rather than hand-crank. Not for fresh graduates.

Practical notes

Brush up ClickHouse internals specifically: MergeTree mechanics, mutations and parts management are named in the listing and make good interview territory. Also expect disaster-recovery scenarios: RTO/RPO tradeoffs, PITR and backup validation. The dual PostgreSQL-ClickHouse scope is the differentiator - address both.
