Senior Silicon Firmware 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 engineers to help achieve that mission.   The Compute Silicon & Manufacturing Engineering (CSME) organization within SCHIE is responsible for design, development, manufacturing and packaging of Microsoft's state-of-the-art computer chips, notably the Azure Cobalt. Our solutions provide sustainable strategic advantages to Microsoft and enable our customers to achieve more.   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 Compute Silicon & Manufacturing Engineering 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 Senior Silicon Firmware Engineer to join the team to support our mission as a key role with Cobalt firmware design, development, and silicon enabling.

The silicon computing development team is seeking passionate, driven and intellectually curious engineers to join our silicon  firmware team covering firmware architecture, development, integration, and quality assurance, for our projects.  This team member will be involved in numerous projects within Microsoft developing firmware for custom silicon on a diverse set of systems.  We are responsible for delivering cutting-edge, custom SoC designs that can perform complex and high-performance functions in the most efficient manner.  In this high impact role on the team, you will be responsible to:   Develop, document, review, and maintain low-level silicon firmware in partnership with hardware design, validation, and software teams. Analyze hardware specifications to architect and implement silicon firmware for IP blocks, including bring-up sequences, power management, security flows, and peripheral initialization. Execute firmware development across the full silicon lifecycle — from RTL simulation and FPGA prototyping through emulation, silicon bring-up, and production. Participate in hardware/firmware co-design to define register interfaces, firmware-visible behaviors, and optimal hardware/firmware partitioning during the design phase. Cross multiple firmware disciplines and domains — boot, security, power, telemetry, debug — adapting to evolving needs throughout the development cycle. Perform firmware integration, packaging, and releases to partners and stakeholders with clear versioning and dependency tracking. Build automation and tooling to accelerate development and enable validation partners with maximum code and collateral reuse. Participate in and champion Agile practices emphasizing quality, team accountability, continuous integration, and iterative improvement. Coordinate priorities and activities with cross-functional engineering stakeholders to deliver committed milestones. Collaborate with IP providers to integrate third-party
