Principal Engineer - Core Cloud Platform

The Core Cloud Platform team is responsible for AlphaSense's entire cloud infrastructure, including AWS account management, networking, data storages, and Kubernetes clusters. We build the underlying platform that supports hundreds of services and is used by over 400 globally distributed engineers. We're scaling into a cell-based architecture, and the number of cells we run is growing fast, taking our Kubernetes footprint from dozens of clusters toward hundreds. This is a Principal Engineer role with real breadth within the cloud platform. You'll set the architectural roadmap for our cloud, Kubernetes, and storage platform as it scales with AlphaSense's growth, and take dedicated ownership of the cloud-side configuration and Helm chart layer that every service depends on. Data storages are a critical part of this surface, and we're looking for genuine depth there.
