Rubrik is defining the future of enterprise data security and management. To power this mission, we require an ultra-reliable, planet-scale data foundation. Our team owns the Metadata Store-a mission-critical, high-throughput component powered by a distributed SQL database. This is not a standard deployment; we operate deep within the stack, pushing the limits of the engine to meet non-negotiable demands for strong consistency, ultra-low latency, and extreme availability across petabytes of data. We are the core enablers, responsible for: Customizing the Core: Developing custom extensions and patches to the database engine to solve complex challenges that off-the-shelf solutions can't handle. Zero-Downtime Infrastructure: Pioneering solutions for seamless, disruption-free cluster lifecycle management, including complex schema and semantic changes during Rolling Upgrades (as showcased in our Metadata support for Rolling Upgrades). Foundational Resilience: Building critical infrastructure tools like Kronos (Distributed Time Synchronization) to manage clock drift and ensure transaction correctness in a distributed environment. Join us to master the complexities of distributed consensus, transactional systems, and high-performance computing at scale, whether on-prem or in the cloud. About the Role : Master Distributed Database Internals Are you passionate about the intricacies of distributed systems and ready to live deep within the database engine? We're seeking a relentless problem-solver to join our core team. Your mission will be to ensure our metadata store remains the most reliable and performant component of the entire Rubrik stack. This opportunity offers a potent mix of dynamism, serious technical challenges, and influence across many teams at the heart of Rubrik's technology stack. What you'll do : The Foundation Builder We are looking for candidates who demonstrate an intrinsic curiosity about how databases and distributed systems truly work under the hood.
