Pre-Si Performance / Tlm Modeling Staff Engineer

Company: Qualcomm India Private Limited

Job Summary

We are seeking a highly skilled and motivated Server Performance Modeling Engineer to join our team, focusing on peripheral subsystem performance. This role involves developing analytical and simulation models to evaluate and optimize the performance of server peripherals such as storage controllers, network interfaces, PCIe devices, and other I/O subsystems. You will work closely with architecture, hardware, and software teams to ensure that peripheral components meet performance targets and integrate seamlessly into server platforms.

Key Responsibilities

• Develop performance models (analytical, simulation-based, or hybrid) for server peripheral subsystems.
• Analyze bottlenecks and latency issues in I/O paths including PCIe, NVMe, NICs, and other peripheral interfaces.
• Collaborate with hardware architects and system engineers to define performance requirements and trade-offs.
• Validate models against real-world measurements and benchmarks.
• Provide insights and recommendations to improve peripheral subsystem performance across server platforms.
• Support design decisions with quantitative data and predictive modeling.
• Stay current with industry trends in server architecture, peripheral technologies, and performance modeling techniques.

Some of the key skills which are required (1-2 key skills will be important):

• 5+ years of experience in performance modeling or analysis of server systems or high-performance computing platforms.
• Strong understanding of peripheral subsystems including PCIe, NVMe, SATA/SAS, Ethernet, and RDMA.
• Knowledge of emerging technologies like CXL, advanced NICs.
• Proficiency in modeling tools and languages such as Python, SystemC.
• Experience with simulation environments and workload characterization.
• Familiarity with server architecture, CPU/memory subsystems, and OS-level I/O stack.
• Excellent problem-solving and communication skills.
• Good understanding of bus protocols like AXI, AHB, QSB
• Experience working in team where close collaboration is required between multiple stakeholders
