Principal Hardware Engineer - Networking

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. 

As Microsoft's cloud business continues to grow the ability to deploy new offerings and hardware infrastructure on time, in high volume with high quality and lowest cost is of paramount importance. To achieve this goal, the Cloud Hardware Systems Engineering (CHSE) team is instrumental in defining and delivering operational measures of success for hardware manufacturing, improving the planning process, quality, delivery, scale and sustainability related to Microsoft cloud hardware. We are looking for engineers with a dedicated passion for customer focused solutions, insight and industry knowledge to envision and implement future technical solutions that will manage and optimize the Cloud infrastructure.  

We are looking for a Principal Hardware Engineer - Networking to serve as a technical leader for complex network switch platforms for Microsoft Azure AI infrastructure. This role will define multi-generation platform strategy and drive execution from requirements and architecture through board design, system integration, validation, manufacturing, and deployment. The ideal candidate will combine deep electrical engineering expertise with architectural judgment, cross-organization influence, supplier leadership, and the ability to turn ambiguous infrastructure needs into scalable platform solutions.

• Define and drive the multi-generation electrical and system architecture roadmap for custom network switch platforms supporting Azure AI infrastructure, including technology insertion, platform reuse, risk retirement, and lifecycle strategy.

• Own platform-level requirements decomposition and architectural tradeoffs spanning network, rack, performance, reliability, availability, serviceability, security, telemetry, manufacturing, cost, and schedule.

• Provide technical authority for switch ASIC, control-plane CPU, BMC, CPLD/FPGA, clocking, reset, power delivery, high-speed Ethernet, retimers, optical modules, cable backplanes, telemetry, and platform-management interfaces.

• Lead architecture and design reviews across schematic, PCB stack-up, signal integrity, power integrity, layout, BOM, component derating, DFT, DFM, DFR, and system integration; establish decision criteria and drive closure of cross-disciplinary issues.

• Establish platform bring-up, electrical validation, margining, interoperability, stress, reliability, and production-test strategies; ensure evidence-based exit criteria and scalable test coverage across development phases.

• Lead resolution of the most complex board-, system-, rack-, manufacturing-, and field-level issues by organizing cross-team debug, forming hypotheses from data, and driving verified corrective actions and prevention mechanisms.

• Provide technical direction to ODM/OEM and technology partners; define deliverables, design-review criteria, quality expectations, and escalation paths while influencing supplier roadmaps and execution.

• Mentor senior engineers, raise engineering standards, and build reusable specifications, design guides, validation methods, reference architectures, and lessons learned across network-switch programs.

Rquired Qualifications:

• Master's Degree in Electrical Engineering, Computer Engineering, Mechanical Engineering, or related field AND 7+ years technical engineering experience OR Bachelor's Degree in Electrical Engineering, Computer Engineering, Mechanical Engineering, or related field AND 8+ years technical engineering experience OR equivalent experience.

Other Requirements:

• Ability to meet Microsoft, customer and/or government security screening requirements are required for this role. These requirements include but are not limited to the following specialized security screenings:
  • Microsoft Cloud Background Check: This position will be required to pass the Microsoft Cloud Background Check upon hire/transfer and every two years thereafter. 

Preferred Qualifications:

• Experience architecting merchant-silicon Ethernet switch platforms for AI, cloud, hyperscale, or datacenter infrastructure. 

• Deep experience with switch ASIC, CPU, BMC, CPLD/FPGA, clocking, reset, power-delivery, telemetry, and hardware-management architectures. 

• Experience with 112G/224G PAM4, high-speed connectors, cable backplanes, retimers, pluggable optical modules, and end-to-end channel-budget tradeoffs. 

• Experience with SONiC hardware enablement, platform APIs, firmware interfaces, and switch-platform management. 

• Demonstrated ability to assess SI/PI analyses, PCB and package constraints, PDN behavior, power transients, thermal interactions, and laboratory correlation data. 

• Experience delivering hardware through architecture, EVT, DVT, PVT, production qualification, and high-volume manufacturing. 

• Experience defining supplier strategy, influencing technology roadmaps, and leading ODM/OEM execution across multiple concurrent programs. 

• Proven technical communication, specification writing, executive-level decision framing, mentoring, and cross-organization influence.
