Microsoft Silicon, Cloud Hardware, and Infrastructure Engineering (SCHIE) is the team behind Microsoft’s expanding Cloud Infrastructure and responsible for powering Microsoft’s “Intelligent Cloud” mission. SCHIE delivers the core infrastructure and foundational technologies for Microsoft's over 200 online businesses including Bing, MSN, Office 365, Xbox Live, Teams, OneDrive, and the Microsoft Azure platform globally with our server and data center infrastructure, security and compliance, operations, globalization, and manageability solutions. Our focus is on smart growth, high efficiency, and delivering a trusted experience to customers and partners worldwide and we are looking for passionate engineers to help achieve that mission.
Microsoft's Hardware Systems organization is developing AI-native silicon and system-level solutions to power the next generation of frontier AI models. The MAIA platform combines custom accelerators, advanced networking technologies, large-scale distributed infrastructure, and cloud-scale software to deliver industry-leading AI training and inference capabilities.
The Platform Systems Engineering (PSE) team is seeking a AI Network HW Systems Engineer to drive the architecture, bring-up, validation, optimization, and deployment of networking infrastructure for next-generation MAIA AI systems. This role sits at the intersection of networking hardware, systems architecture, AI infrastructure, and hyperscale deployment.
You will work across the entire networking stack, from high-speed SerDes interfaces, optics, cables, NICs, PHYs, and switch silicon to AI communication frameworks and distributed training workloads. You will collaborate with architects, silicon engineers, firmware developers, hardware designers, validation teams, OS developers, manufacturing partners, and Azure service teams to deliver scalable, reliable, and high-performance AI networking solutions.
This is a unique opportunity to influence the future of AI infrastructure while enabling Microsoft's next generation of frontier-scale AI systems.
