Job description

Azure Cosmos DB is Microsoft’s next generation globally distributed, massively scalable, multi-model cloud database service. It is designed to enable developers to build planet-scale applications. Azure Cosmos DB is one of the fastest growing Azure services. This role provides a lot of scope for impact, given the high visibility problems the team is solving. This position is on the Cosmos DB compute platform team. Our mission is to build a multi-tenant platform for new compute intensive services that operate on storage layer of Cosmos DB e.g. in-memory graphs, ultra-low latency caches, materialized views. The Cosmos compute platform offers a chance to leverage and grow your understanding of distributed systems to work on a new massively scalable, highly reliable foundational service from ground up. We are looking for highly motivated and self-driven individuals who are passionate in the areas of multi-threading, High Availability and Distributed Systems. Joining the Azure Cosmos DB team is a fantastic opportunity to work with highly talented engineers operating like a startup, and to deliver on our next set of big challenges. Responsibilities You will be responsible for building a new massive scale multi-tenant platform which will serve as a foundation for new services operating on data in our storage layer and solve the challenges that come along the way. Qualifications Bachelor’s/Master’s/PhD with work or research experience in computer science or related field. 8+ years of experience in developing quality products and services, preferably in systems and backend services with experience in C#, C, C++, or Java. Passion for large scale distributed system. Experience with multi-threaded/parallel programming/perf tuning. Proven track record in designing and delivering quality software.
