Principal Software Engineer - Azure Data Lake Storage Redmond, WA

Principal Software Engineer - Azure Data Lake Storage job at Microsoft Corporation. Redmond, WA. The Azure Data Lake Storage team is on a mission to build the data foundation that powers the Artificial Intelligence (AI) revolution, and we are looking for engineers to help lead the way.

We are seeking a Principal Software Engineer to design and build the next generation of intelligent storage systems purpose‑built for the most demanding AI and Machine Learning (ML) workloads in the world.

The landscape of computing is shifting. Massive foundation models, generative Artificial Intelligence (AI), and real‑time inferencing are redefining how data moves, scales, and performs.

Azure Data Lake Storage is evolving beyond traditional storage to become an AI‑native platform‑one that seamlessly supports the unique scale, throughput, and latency demands of modern AI. From high‑bandwidth training pipelines to ultra‑low latency for model serving and inference, you will help architect systems that fuel innovation at zettabyte scale.

This is a rare opportunity to work on one of the largest and most ambitious storage platforms on the planet, in close partnership with leaders in Artificial Intelligence (AI).

As a Principal Software Engineer
, you will shape system architecture for the next era of AI storage with a focus on multi‑region AI, drive technical innovation across design, development, and operations, tackle complex and high‑impact engineering challenges at hyperscale, and guide teams to build high‑quality solutions.

If you are ready to help define how storage powers AI at global scale, join us and help build the infrastructure that will shape the future.

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.
