Core Systems

Distributed systems for a large-scale geo-replicated infrastructure

About Core Systems

Our Core Systems engineers and researchers design, build, and deploy the foundation of Meta’s private cloud that powers Meta’s infrastructure and meets our business needs. Our work spans across the engineering spectrum of research, development, deployment, and production as we ensure that our systems run efficiently, reliably, and securely across millions of machines in tens of geo-replicated data center regions.

Core Systems performs state-of-the-art R&D in the area of distributed systems and architecture at a global scale. Billions of people rely on the services we build and manage to connect and communicate. Throughout the lifecycle of these distributed services, we encounter fundamental technical challenges in multiple areas, including cluster management, serverless computing, configuration management, global routing, deployment, fault tolerance, performance, reliability, scalability, service discovery, and storage systems.

We are hiring infrastructure engineers with 5+ years of experience to tackle exciting hyperscale challenges; please reach out to
