OverviewDo you want to be at the forefront of innovating the latest hardware and systems designs to propel Microsoft's cloud growth? Are you seeking a unique career opportunity that combines technical capabilities, cross-team collaboration, with business insight and strategy? Join our Leading-Edge Architecture Pathfinding (LEAP) team within the System Planning and Architecture (SPARC)organization in Azure Hardware Systems & Infrastructure (AHSI). AHSI is the team behind Microsoft's expanding cloud business, responsible for delivering the hardware systems and infrastructure for cloud computing across Microsoft Azure, Bing, MSN, Office 365, OneDrive, Skype, Teams and Xbox Live. The SPARC organization is responsible for strategy, planning and architecture pathfinding, and manages Azure's hardware roadmap from architecture concept, through production for Microsoft's current and future offerings. The LEAP team within SPARC is at the forefront of systems architecture and technology pathfinding spanning compute, memory, storage, and system interconnects. Drawing on deep insights of workloads, emerging technology trends, and focused industry engagements, LEAP team's charter is to define and evaluate novel systems architecture innovations through hardware/software co-design and advance them through technical readiness for productization. The LEAP team is seeking a Principal Software Engineer who will be part of the team to develop hardware/software co-design, software prototyping, and building reference designs to enable pathfinding for novel system architecture spanning OS(Windows/Linux) memory management, memory overcommit, memory disaggregation, data acceleration and resource virtualization capabilities.
