Responsibilities

AlphaSense runs a large-scale, Kubernetes-native platform built on a modern microservices architecture, serving the majority of the Fortune 500. We are moving it to a cell-based architecture, where each cell is an independent deployment of the platform.
The hardest part is data. Our platform relies on a broad ecosystem of data platforms and storage systems, including Vespa, MongoDB, ClickHouse, Redis, ScyllaDB, PostgreSQL, Temporal, and Kafka, to name a few. This role is focused on the Data Platform: the capabilities that let engineering teams build, run, and scale their storage at large scale without each team becoming an expert in every system.
We prefer managed solutions over self-hosted ones, and we expect engineers to own their storage. Teams run what they build, and this role makes that model work at scale: you build it, you run it, and you scale it. Your job is to give teams the platform, standards, and tooling to do that safely, and to own the reliability and scalability of the platform itself.
Help set the architecture and roadmap for the Data Platform and the storage ecosystem behind it
Build the capabilities for large-scale data migrations across cells, regions, and geographies, including tooling for moving, splitting, validating, and rolling back data with minimal downtime
Enable product teams self-service ways to provision, operate, and scale their own storage
Drive the data-layer changes that cell-based architecture requires, including data placement, tenant routing, replication, and isolation
Define and apply the managed-first approach: choose managed services where they fit, and build and run self-managed systems only where there is a clear reason
Find and close scalability gaps in data stores across regions, cells and deployment models
Build shared libraries that give product teams self-service storage capabilities
Closely partner with Cloud Platform, SRE, and DevEx teams
Raise the architectural bar across the organization and mentor Staff and Senior engineers
