Staff Silicon Power Performance Engineer — System Level Test & Characterization

Job Title

Staff Silicon Power Performance Engineer — System Level Test & Characterization

Role Summary

Work on post-silicon system-level test and characterization to validate power, performance, and thermal behavior of Arm silicon platforms. The role sits within the hardware engineering/validation teams in Bengaluru and collaborates with SoC architecture, firmware, validation, and systems teams to identify and resolve silicon issues.

Experience Level

Senior — typically requires 8+ years of post-silicon characterization or validation experience.

Responsibilities

Execute and lead silicon characterization activities, build automation and reporting infrastructure, and collaborate cross-functionally to close power and performance issues.

• Plan and execute silicon PVTF characterization across multiple projects and platforms.
• Design and develop scalable automation frameworks, regression infrastructure, data collection flows, dashboards, and reporting tools.
• Measure and analyze leakage/static, active-idle, dynamic, and boot power to identify bottlenecks and optimization opportunities.
• Characterize voltage droop and loadline impedance; validate power delivery and VRM/PMIC behavior.
• Port and enable industry-standard, customer, and stress workloads for silicon characterization and benchmarking.
• Debug silicon issues with SoC architecture, firmware/bootloader, validation, and systems teams; support silicon bring-up and board enablement.
• Analyze large instrumentation and telemetry datasets to inform optimization and correlation activities.

Requirements

Key technical skills and domain experience required and desirable.

Must-have:

• 8+ years of post-silicon characterization or validation experience focused on power/performance.
• Experience characterizing SoC IPs such as CPU, interconnect, DDR, PCIe, UCIe, or high-speed I/O subsystems.
• Hands-on use of lab equipment: oscilloscopes, DAQ systems, thermal chambers, power analyzers, and measurement/control devices.
• Understanding of power and performance optimization techniques and power delivery networks.
• Familiarity with benchmarking and profiling tools (e.g., SPEC2017, LMBench, stress-ng, fio, iPerf or equivalents).
• Ability to analyze and interpret large datasets from instrumentation and telemetry systems.
• Experience working with firmware, bootloader, UEFI/BIOS, ACPI, or device tree flows.

Nice-to-have:

• Experience performing VMIN analysis, pre-silicon modeling/simulation/emulation or FPGA platforms.
• Experience correlating pre- and post-silicon power and performance results.
• Scripting in Python, Shell, Perl and low-level programming in C/C++.
• Experience validating power management features (DVFS, AVS, thermal throttling).
• Understanding of Arm architecture and platform power/performance trade-offs.
• US B1/B2 visa (listed as a preference).

Education Requirements

Bachelor's degree in science or engineering is indicated as required; a master's degree is preferred. Relevant technical engineering or science backgrounds are expected.
