You can reason from incomplete information without hiding uncertainty, connect microarchitectural mechanisms to observed bottlenecks, and communicate the result in a way that is useful to both deep technical experts and senior decision-makers. You are equally comfortable with performance counters, analytical models, diagrams and written argument., * Deep hands-on experience in CPU microarchitecture, silicon performance, system architecture or performance modeling. * Strong knowledge of out-of-order pipelines, branch prediction, fetch and decode, execution back ends and simultaneous multithreading behavior. * Expertise in cache, TLB, coherence, prefetching, memory controllers, NUMA, bandwidth, latency and capacity scaling. * Experience with hardware performance counters, profiling tools, microbenchmarks, system telemetry and bottleneck analysis. * Strong quantitative and scripting or data-analysis skills used in performance investigations. * Ability to reason from incomplete information, make assumptions explicit and show which unknowns can change the conclusion. * Clear technical writing and visualization skills, with a commitment to configuration control, peer review and reproducibility. PREFERRED EXPERIENCE: * Pre-silicon performance modeling, architecture exploration or simulation experience. * Hands-on analysis of more than one server CPU architecture or ISA. * Experience with memory-intensive workloads, virtualization, HPC, analytics or CPU-side AI workloads. * Familiarity with power modeling, thermals, platform firmware and frequency or power-management behavior. * Experience evaluating vendor disclosures, patents, conference presentations or public technical materials under clean-room rules., * Bachelors or Masters degree in electrical or computer engineering ## Description AMD is looking for an engineer who can build workload-relevant models of future AMD and competitor server platforms before silicon is available. You will convert public disclosures, measured behavior, partner-authorized data and software or platform observations into explicit assumptions about future Intel, Arm, hyperscaler custom, NVIDIA, Qualcomm and emerging CPU designs. This is not a static feature-comparison role; the work must explain what a platform is likely to deliver on real workloads, why, and with what level of confidence., * Develop comparative models of CPU front ends, execution resources, branch behavior, cache and TLB hierarchies, coherence, memory subsystems and multi-socket or NUMA behavior. * Model platform constraints and advantages including memory bandwidth and capacity, DDR or HBM attachment where relevant, PCIe, CXL, networking, storage paths, power limits and thermals. * Translate incomplete roadmap disclosures into explicit assumptions with confidence levels, alternate cases and sensitivity ranges. * Use measured silicon, performance counters and platform telemetry to calibrate models and identify failing assumptions. * Perform bottleneck decomposition that explains why a workload favors AMD or a competitor and which architectural mechanism is responsible. * Work with workload engineers to create microbenchmarks and kernels that isolate high-value architectural effects. * Evaluate ISA and acceleration features in the context of real application uplift rather than theoretical peak capability. * Quantify performance-per-watt, platform power and rack-density implications when architectural choices change system behavior. * Maintain version-controlled assumptions, sources, revisions and uncertainty so forecasts can be peer reviewed and reproduced. * Create architecture diagrams, technical narratives and executive-ready content that clearly show causes, risks and areas of AMD advantage., * Build models before silicon and then see them tested, calibrated and improved against real systems. * Work across the full path from pipeline behavior to memory, I/O, power and rack-level consequences. * Shape where AMD investigates, optimizes and invests by identifying architectural risk early. * Develop broad influence across architecture, workload engineering, forecasting and platform teams., AMD may use Artificial Intelligence to help screen, assess or select applicants for this position.
