Overview
Microsoft Silicon, Cloud Hardware and Infrastructure Engineering (SCHIE) powers Microsoft’s Intelligent Cloud mission, delivering core infrastructure and foundational technologies for Microsoft’s online businesses and Azure globally. We are looking for passionate engineers to help achieve this mission via scalable, high-quality, low-cost hardware infrastructure and operations. We are seeking a Principal AI Network Architect to join the Cloud Hardware Systems Engineering (CHSE) team, focused on defining and delivering operational measures of success for hardware manufacturing, improving planning, quality, delivery, scale, and sustainability related to Microsoft cloud hardware. Responsibilities
Technology Leadership : Spearhead architectural definition and innovation for next-generation GPU and AI accelerator platforms, focusing on ultra-high bandwidth, low-latency backend networks. Drive system-level integration across compute, storage, and interconnect domains to support scalable AI training workloads. Cross-Functional Collaboration : Partner with silicon, firmware, and datacenter engineering teams to co-design infrastructure that meets performance, reliability, and deployment goals. Influence platform decisions across rack, chassis, and pod-level implementations. Technology Partnerships : Cultivate deep technical relationships with silicon vendors, optics suppliers, and switch fabric providers to co-develop differentiated solutions. Represent Microsoft in joint architecture forums and technical workshops. Architectural Clarity : Evaluate and articulate tradeoffs across electrical, mechanical, thermal, and signal integrity domains. Frame decisions in terms of total cost of ownership, performance, scalability, and deployment risk. Lead design reviews and contribute to PRDs and system specifications. Industry Influence : Shape the direction of hyperscale AI infrastructure by engaging with standards bodies (e.g., IEEE 802.3), influencing component roadmaps, and driving adoption of novel interconnect protocols and topologies. Qualifications
Required Qualifications
Bachelor’s Degree in Electrical Engineering, Computer Engineering, Mechanical Engineering, or related field AND 8+ years technical engineering experience OR Master’s Degree in Electrical Engineering, Computer Engineering, Mechanical Engineering, or related field AND 7+ years technical engineering experience OR equivalent experience 5+ years of experience in designing AI backend networks and integrating them into large-scale GPU systems Other Requirements
Ability to meet Microsoft, customer and/or government security screening requirements. These include the Microsoft Cloud Background Check upon hire/transfer and every two years thereafter. Preferred Qualifications
Proven expertise in system architecture across compute, networking, and accelerator domains Deep understanding of RDMA protocols (RoCE, InfiniBand), congestion control (DCQCN), and Layer 2/3 routing Experience with optical interconnects (e.g., PSM, WDM), link budget analysis, and transceiver integration Familiarity with signal integrity modeling, link training, and physical layer optimization Experience architecting backend networks for AI training and Inference workloads, including Hamiltonian cycle traffic and collective operations (e.g., all-reduce, all-gather) Hands-on design of high-radix switches (≥400Gbps per port), orthogonal chassis, and cabled backplanes Knowledge of chip-to-chip and chip-to-module interfaces, including error correction and equalization techniques Experience with custom NIC IPs and transport layers for secure, reliable packet delivery Familiarity with AI model execution pipelines and their impact on pod-level network design and latency SLAs Prior contributions to hyperscale deployments or cloud-scale AI infrastructure programs Compensation and Benefits
Hardware Engineering IC5 - The typical base pay range for this role across the U.S. is USD 139,900 - 274,800 per year. There is a different range applicable to specific work locations, within the San Francisco Bay area and New York City metropolitan area, and the base pay range for these locations is USD 188,000 - 304,200 per year. Certain roles may be eligible for benefits and other compensation.
