Are you excited about the possibility of working on the largest Object Storage service in the world? Azure Storage team is 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 – Blob Storage, Table Storage (NoSql Key Value store), Queue Storage, File Storage (new SMB based File Storage) and Disk Storage. We are one of the foundational services in the Azure Cloud. The service hosts data from some of the largest companies in the world plus supports all of Microsoft’s largest online businesses including Xbox, Skype and Bing and has scaled to store exabytes of customer data with the roadmap looking even better in terms of growth.

You can read more about the Service architecture here and about the current storage offerings here.

Storage is divided into three main layers – with the Partition Layer forming the heart of the system and provides the transactional support, querying capability, indexing, geo replication and multi tenancy. 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. The problem space we are exploring includes better isolation across different tenants, better scheduling of requests and background activities, geo replication as well as improved indexing. 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.


The specific role for this position is to work on the indexing system of the storage service. We want to build additional indexing support for our various offerings as well as add indexing support for parts of our service which don't have one. These indices have to scale to serve PBs of data with tight guarantees around latencies and transactional semantics.

To be successful, you must thrive on solving problems related with data durability, availability and concurrency issues in a multi-tenant environment. You must have passion for storage and distributed systems. You will be challenged on a daily basis as you build the largest storage solution Microsoft has.
