Systems Architect: Memory Wall Exploration

Responsibilities

• Analyze how AI workloads interact with system resources across CPU, GPU, and AI accelerators
• Evaluate the impact of memory bandwidth, latency, contention, and data movement on performance and power efficiency
• Characterize workload behavior in shared-memory systems, including foreground and background activity interactions
• Identify sources of performance variability and degradation in multitasking scenarios
• Optimize data movement between CPUs, GPUs, and memory (DRAM, HBM, CXL) to overcome memory wall bottlenecks
• Translate memory and system-level constraints into actionable guidance for platform architecture, runtime, and power teams
• Define execution envelopes and tradeoffs to improve AI experience predictability
• Collaborate with internal teams and external ecosystem partners, including memory and silicon vendors, to align on platform roadmaps and capabilities
• Assist in defining internal tools, metrics, and evaluation methods for assessing AI workload behavior

Requirements

• M.Sc. in Computer Engineering, Electrical Engineering, or a related discipline
• Strong background in systems performance, platform architecture, or runtime behavior
• Solid understanding of memory hierarchy (DRAM, SRAM, cache) and interconnect protocols (CXL, PCIe)
• Experience with heterogeneous compute environments (CPU, GPU, accelerators)
• Proficiency in C/C++ and Python scripting for modeling and analysis
• Experience with Machine Learning hardware acceleration and processing-in-memory (PIM) techniques

Preferred Qualifications

• Experience with client platforms (PC, mobile, embedded) and on-device AI inference workloads
• Knowledge of low-power design and power-sensitive system design
• Experience with performance analysis tools, telemetry, and data-driven evaluation
• Prior experience engaging with memory or silicon vendors in a technical capacity
• Experience with architectural simulators such as GEM5 or Sniper

Benefits

• Health, dental, and vision insurance
• Long term and short term disability insurance
• Employee assistance program and flexible spending accounts
• Life insurance
• Generous time off policies, including 4-12 weeks of fully paid parental leave
• 11 paid holidays
