Description
OverviewMicrosoft 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 next generation of cloud infrastructure is increasingly constrained not just by compute capability, but by power, performance efficiency, rack density, and how effectively every watt of infrastructure is converted into useful work.
We are looking for an experienced Principal Platform Power & Performance Engineer to help shape the power and performance architecture of Azure Compute and AI infrastructure.
In this role, you will work at the intersection of silicon, servers, firmware, operating systems, accelerators, workloads, and datacenter infrastructure. You will characterize real systems, identify efficiency bottlenecks, influence platform architecture, and develop optimizations that improve performance per watt while preserving workload performance and reliability.
The impact goes well beyond benchmark tuning. Your work can influence how Azure platforms are designed, configured, provisioned, and operated across Compute and AI infrastructure.
Come join this exciting and growing Cobalt team through our monumental evolution of cloud hardware at Azure and Microsoft!   
#SCHIE
Responsibilities
Own end-to-end power and performance characterization of next-generation Azure compute platforms, from silicon and server bring-up through workload-level validation.
Analyze the interaction between CPU/GPU utilization, memory, PCIe/I/O, firmware, OS power management, thermals, cooling, and workload behavior.
Identify opportunities to improve:
Performance per watt
Idle and low-utilization efficiency
Energy proportionality
Rack power efficiency and density
Workload throughput within platform power constraints
Develop and evaluate dynamic power/performance-management strategies across idle, partially utilized, and fully loaded systems.
Profile representative cloud and AI workloads to understand where energy is consumed and determine which system-level optimizations deliver meaningful efficiency improvements.
Partner closely with silicon vendors, OEM/ODM partners, firmware teams, OS engineers, Azure Compute and AI infrastructure teams, and datacenter engineering teams to drive improvements from concept through production.
Influence silicon features, BIOS/firmware policies, OS power management, platform controls, thermal strategies, and future hardware architecture using measured engineering data.
Build telemetry and analysis methodologies that connect low-level platform behavior with workload performance and infrastructure-level efficiency.
Diagnose complex cross-layer performance and power issues spanning hardware, firmware, kernel/OS, drivers, accelerators, and workloads.
Translate engineering findings into recommendations that can influence fleet efficiency, capacity utilization, power provisioning, infrastructure cost, and future platform roadmaps.
Provide technical leadership across multiple platform programs, define methodology and strategy, and drive ambiguous cross-organizational problems from investigation to deployment.

CPU microarchitecture and power states
Memory subsystems
PCIe and high-speed I/O
BIOS/UEFI and firmware
OS/kernel power management
Thermal and cooling behavior
Hands-on experience with platform performance analysis using tools such as Linux perf, hardware performance counters, tracing/profiling tools, telemetry systems, or equivalent Windows/Linux tooling.
Ability to design controlled experiments, interpret noisy system-level data, establish correlations, and distinguish workload effects from platform bottlenecks.
Experience debugging performance or power issues that cross multiple hardware/software layers.
Proven scripting and data-analysis skills using Python, PowerShell, Bash, Kusto, or similar technologies.
Excellent communication skills and the ability to translate detailed engineering analysis into decisions for architecture, product, and leadership audiences.
Experience in one or more of the following would be particularly relevant:
Large-scale cloud or hyperscale infrastructure
AMD, Intel, Arm, NVIDIA, or other modern CPU/GPU platforms
GPU and AI/ML workload characterization
Power capping, DVFS, CPU/GPU power states, memory power management, or PCIe power management
Server/rack power modeling and telemetry
AI training or inference performance
Performance-per-watt benchmarking
Firmware or BMC-based platform controls
Thermal and fan optimization
Workload-aware or utilization-aware power management
Capacity, rack-density, or datacenter power optimization
