Are you excited about the possibility of changing the world by working on the largest Object Storage service in the world? Come join the Azure Storage team in building Azure Data Lake Storage and revolutionize the way Cloud Storage supports Big Data and AI!

The Azure Storage team is currently chartered with building, managing, and running the Persistent Cloud Storage for Microsoft Azure Cloud. Azure Storage consists of a Storage Platform which currently powers five different storage services – Azure Data Lake Storage, Blob Storage, Table Storage (NoSql Key Value store), Queue Storage, File Storage (SMB based File Storage) and Disk Storage. We are one of the foundational services in the Azure Cloud. This service hosts data from some of the largest companies in the world plus supports all of Microsoft’s largest online businesses including Xbox, One Drive, Skype and Bing, and has scaled to store exabytes of customer data with the roadmap looking even better in terms of growth. We have built a new foundational Storage service with ADLS (Azure Data Lake Storage) Gen 2 and one of the underpinnings of that is a scalable Hierarchical Namespace technology stack which this position is for.

You can read more about the Azure Storage Service architecture here: (https://blogs.msdn.microsoft.com/windowsazurestorage/2011/11/20/sosp-paper-windows-azure-storage-a-highly-available-cloud-storage-service-with-strong-consistency/)

and watch an overview specifically about Azure Storage’s Hierarchical Namespace here: Building File System Semantics for an Exabyte Scale Object Storage System

As a Principal Software Engineer in Azure Data Lake Storage team, you will work on the Hierarchical Namespace layer of Azure Storage, which forms the heart of File System semantics that are provided for Azure Data Lake Storage and is a critical part of Azure Storage’s Analytics and AI strategy. The Hierarchical Namespace provides: horizontally scalable hierarchical file system topology and capabilities, distributed transaction support, distributed caching of the hierarchy and namespace metadata, support for a variety of interfaces/protocols and Interoperability between them, geo replication, partitioning, multi tenancy, and many other capabilities. Additionally, this opportunity will allow you to work cross many layers of the Azure Storage system and Azure as a whole, presenting unique engineering challenges for which we need top-notch talent. Right now is an exciting time for the team as we are working on expanding the range of supported scenarios for the service while working on the next version architecture of the storage service to support the next 100X growth. If you are excited about large scale data management problems, this is a unique opportunity to have an impact in a team unlike any other.

Microsoft’s mission is to empower every person and every organization on the planet to achieve more. As employees we come together with a growth mindset, innovate to empower others, and collaborate to realize our shared goals. Each day we build on our values of respect, integrity, and accountability to create a culture of inclusion where everyone can thrive at work and beyond.
