Principal Researcher

Microsoft is a company where passionate innovators come to collaborate, envision what can be and take their careers further. This is a world of more possibilities, more innovation, more openness, and the sky is the limit thinking in a cloud-enabled world.

Microsoft’s Azure Data engineering team is leading the transformation of analytics in the world of data with products like databases, data integration, big data analytics, messaging & real-time analytics, and business intelligence. The products our portfolio include Microsoft Fabric, Azure SQL DB, Azure Cosmos DB, Azure PostgreSQL, Azure Data Factory, Azure Synapse Analytics, Azure Service Bus, Azure Event Grid, and Power BI. Our mission is to build the data platform for the age of AI, powering a new class of data-first applications and driving a data culture.

Within Azure Data, the databases team builds and maintains Microsoft's operational Database systems. We store and manage data in a structured way to enable multitude of applications across various industries. We are on a journey to enable developer friendly, mission-critical, AI enabled operational Databases across relational, non-relational and Open Source Software (OSS) offerings.

Azure Cosmos DB is building performant and cost-effective systems for vector search and AI-based information retrieval to enable search, recommendations and Retrieval-Augmented Generation (RAG) scenarios. We are innovating both on the research (e.g., see DiskANN project) and engineering. ​​We are hiring a Principal Researcher with expertise in dense retrieval, semantic re-ranking, GraphRAG or related areas. The role would involve developing the state-of-the-art techniques in these areas, advising the team on designing and building these systems.
