Microsoft Silicon and Cloud Hardware Infrastructure Engineering (SCHIE) is the team behind Microsoft’s expanding cloud infrastructure, powering the company's Intelligent Cloud and AI platforms through industry-leading silicon, systems, and hardware innovation.
Are you passionate about building cutting-edge technologies in an environment that embraces a growth mindset? Do you want to help shape the future of AI infrastructure while contributing to Microsoft's mission to empower every person and every organization on the planet to achieve more?
The Firmware Center of Excellence (FW CoE) within SCHIE is responsible for delivering the hardware and firmware technologies that power Azure infrastructure. As part of this organization, we are seeking a Principal Firmware Engineer to lead the design and evolution of Microsoft's AI accelerator validation and performance characterization frameworks, supporting the MAIA roadmap and future generations of Azure AI silicon.
In this role, you will drive the architecture and development of scalable stress, validation and performance characterization solutions used across Microsoft's AI accelerator programs. You will work at the intersection of system architecture, firmware, software, performance engineering, AI workloads, and silicon validation to enable high-confidence silicon bring-up, characterization, and deployment at hyperscale. You will partner closely with teams spanning these disciplines to develop and operationalize validation frameworks and workload solutions that exercise compute, memory, networking, and platform infrastructure under both synthetic stress conditions and representative customer AI workloads. Your work will directly influence silicon readiness, platform quality, performance optimization, and production deployment of Microsoft's next-generation AI infrastructure.
We are looking for a technically strong leader who combines deep systems expertise with a passion for solving complex engineering problems, driving cross-organizational impact, and mentoring teams to deliver world-class solutions at cloud scale. You will be working on latest state-of-the art technologies, in a fun environment with a talented group of individuals with diverse backgrounds and skillsets and located in different geographic locations.
