WHY BOX NEEDS YOU

Core Data at Box powers the most fundamental layer of Box’s content platform, enabling millions of queries per second across a highly available and consistent relational data tier. Within Core Data, the Resilience team ensures that the services stay healthy, performant, and fault-tolerant - especially under load.

We're looking for a Senior Software Engineer to join this Resilience team and help drive system improvements that protect Core Data’s MySQL, Memcached, and Redis-based data tier and evolve how services like Credence (Core Data’s interface layer) scale and self-heal. Collaborating with teams across Core Data and across the organization, you will help build resilient features, automate failure handling, and define best practices around some of our hardest load and resilience-related challenges. You’ll help shape how Box engineers interact with our relational data layer, while supporting our broader technical vision of transforming our relational data tier into a truly self-contained platform.
