About The Position

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 Microsoft Fabric platform team builds and maintains the operating system and provides customers with a unified data stack to run an entire data estate. This platform offers consistent experience, centralized governance, a cohesive business model, and integrated architecture. The OneLake team within Azure Data is focused on building OneLake—Microsoft Fabric’s comprehensive, centralized data lake designed for the entire organization. OneLake simplifies data management by consolidating all data into a single, consistent platform, making it easier to access, oversee, and analyze information on a scale. Furthermore, the Interop model enables independent software vendors (ISVs) to integrate their solutions with OneLake and Fabric.
As a Principal Software Engineer on the OneLake & ISVs team, you will collaborate closely with engineers across other Fabric services and external partners to define user requirements and architect services from the ground up. This role involves driving customer-focused feature development, onboarding partners, and supporting strategic relationships in a dynamic, fast-paced environment. Your work will play a key part in helping partners build, share, and grow with Microsoft, making sure there is deep integration into the Fabric ecosystem.
Success in this role means delivering robust, low-latency solutions that enhance partner integration, leveraging modern AI tools such as Microsoft Copilot and GitHub Copilot. You will thrive in a fast-paced environment, maintain high standards for quality and security, and continuously seek and provide feedback to foster innovation and growth. You are expected to embody Microsoft’s values of respect, integrity, and accountability, contributing to an inclusive culture where everyone can succeed.
We do not just value differences or different perspectives. We seek them out and invite them in so we can tap into the collective power of everyone in the company. As a result, our customers are better served.
