You will help define power-management features, build workloads that reveal how the design consumes power, and turn measurement and analysis into changes that improve performance per watt. This is a hands-on role working with architecture, verification, RTL, physical design, firmware, and silicon validation teams.\nCore Responsibilities\nDefine and evaluate silicon power-management features, including clock gating, power gating, idle states, and dynamic voltage and frequency scaling. Specify expected power savings, performance impact, and conditions for entering and exiting each state.\n\nDevelop representative, high-activity, and corner-case workloads for power measurement in simulation, emulation, and silicon. Work with verification and software teams to make workloads reproducible and representative of intended use.\n\nEstablish power targets for IP blocks and dies. Produce power rollups across workloads, operating points, and design revisions, including dynamic and leakage power where appropriate.\n\nRun and interpret RTL and gate-level power analysis. Use switching activity, power reports, and design data to identify major contributors, unexpected activity, and gaps against targets.\n\nPartner with RTL teams to evaluate changes such as improved clock enables, operand isolation, reduced unnecessary data movement, and more effective low-power states.\n\nPartner with physical design teams to understand the power impact of synthesis, clock distribution, placement, and implementation choices. Balance proposed savings against timing, area, and performance.\n\nBuild and refine power models and analysis flows so architectural estimates can be compared with implementation results and, when available, measured silicon data.\n\nTrack power optimizations from proposal through implementation and measurement. Quantify the savings achieved and document any performance or functional tradeoffs.\n\nCommunicate power trends, risks, and recommendations to design and architecture teams throughout the silicon development cycle.\n\nMinimum Education and Experience\nBachelor’s degree in electrical engineering, computer engineering, or a related field, or equivalent practical experience.\n\nAt least 5 years of relevant experience in ASIC or SoC design, power analysis, low-power design, or silicon power optimization.\n\nHands-on experience analyzing power from RTL or gate-level designs and using the results to identify design improvements.\n\nWorking knowledge of Verilog or SystemVerilog, digital design, and the effects of switching activity, clocks, voltage, and leakage on power.\n\nExperience developing or selecting workloads and activity traces for power estimation, and communicating results to design teams.\n\nProficiency with scripting or data analysis, preferably using Python.\n\nPreferred Experience\nExperience defining and validating clock-gating, power-gating, idle-state, or DVFS features.\n\nExperience with industry-standard RTL or gate-level power analysis tools and automated power regressions.\n\nExperience correlating pre-silicon estimates with lab power measurements and investigating differences.\n\nFamiliarity with physical design flows, clock trees, UPF, and power-aware verification.\n\nExperience optimizing power in large compute SoCs or multi-die designs.","description_format":"text","description_chars":3373,"description_truncated":false,"requirements":{"experience_years_min":5,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"bachelor","optional":false},"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[{"name":"United
