Principal Subsystem Design Engineer

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 Artificial Intelligence System on Chip (AISoC) 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 Subsystem Design Engineer to join the team.

• Drive design implementation, including microarchitecture specification, RTL development and integration using Verilog/SystemVerilog, synthesis, timing constraints, floor-planning considerations, performance optimization, and design-quality closure including CDC, lint, and RDC. 

• Debug complex design and system-level issues across simulation, emulation, and silicon, working across disciplines to identify root causes and implement effective solutions. 

• Drive execution in an Agile development environment, including sprint planning, feature deployment, code reviews, issue resolution, and continuous improvement of design and verification processes. 

• Champion high-quality engineering execution and contribute to delivering cutting-edge, custom IP and SoC solutions that meet demanding performance, power, efficiency, and schedule requirements. 

Required Qualifications:

• Doctorate in Electrical Engineering, Computer Engineering, Computer Science, or related field AND 3+ years technical engineering experience
• OR Master's Degree in Electrical Engineering, Computer Engineering, Computer Science, or related field AND 6+ years technical engineering experience
• OR Bachelor's Degree in Electrical Engineering, Computer Engineering, Computer Science, 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. 

• This role will require access to information that is controlled for export under export control regulations, potentially under the U.S. International Traffic in Arms Regulations or Export Administration Regulations, the EU Dual Use Regulation, and/or other export control regulations.  As a condition of employment, the successful candidate will be required to provide either proof of their country of citizenship or proof of their US. residency or other protected status (e.g., under 8 U.S.C. 1324b(a)(3)) for assessment of eligibility to access the export-controlled information. To meet this legal requirement, and as a condition of employment, the successful candidate’s citizenship will be verified with a valid passport. Lawful permanent residents, refugees, and asylees may verify status using other documents, where applicable.   

Preferred Qualifications:

• 9+ years of experience in RTL design with a proven track record of delivering high-performance IP, SS, or SoC designs such as PCIe, DDR, or HBM. 

• Expertise in microarchitecture specification, RTL coding, and design verification collaboration. 

• Experience in synthesis, timing constraints, power / performance / area (PPA) trade-offs and post-silicon debug. 

• Experience with design quality and static checks, DFT implementation and hand off to physical design. 

• Lead experience for an IP or SS related to CPUs, VPUs, GPUs, Direct Memory Access (DMA) engine, Tensor unit, or similar
