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 a Principal Signoff CAD Engineer 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 Methodology, Infrastructure, Silicon Engineering, and Labs engineering (MILE) 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 a Principal Signoff CAD Engineer with a 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 Signoff CAD Engineer specializing in silicon signoff to join the team. In this role, you will own the signoff CAD strategy and flow architecture across parasitic extraction, static timing analysis, power integrity, and physical verification for Microsoft’s next-generation silicon programs. You will bring experience across the full signoff tool ecosystem—including StarRC/Pegasus, PrimeTime/Tempus, Redhawk-SC/Voltus, and Fusion Compiler/Innovus—and a record of driving quality, growth, and technical leadership at scale.

• Own and architect the end-to-end silicon signoff CAD flow strategy across parasitic extraction (StarRC/Pegasus), static timing analysis (PrimeTime/Tempus), power integrity and IR-drop analysis (Redhawk-SC/Voltus), and physical verification, ensuring production-quality convergence for advanced-node silicon programs.
• Drive deep quality improvements across signoff methodologies by establishing best practices, defining quality metrics, and implementing systematic validation frameworks that prevent silicon escapes and reduce re-spins.
• Lead technical engagement with EDA vendors (Synopsys, Cadence) to evaluate, qualify, and deploy new signoff tool versions; drive resolution of critical tool issues and influence vendor roadmaps to align with Microsoft’s silicon development needs.
• Collaborate with physical design construction teams and front-end RTL teams to ensure seamless integration between implementation and signoff, driving convergence of timing, power, and physical verification closure across multiple concurrent silicon programs.
• Grow the signoff engineering team by establishing technical standards, conducting design reviews, and fostering a culture of continuous improvement; serve as the technical authority for signoff decisions and trade-offs across the organization.

Required Qualifications:

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.
