About the Job

Requirements

  • The role requires 15+ years of relevant industry experience in CPU or high-performance ASIC/SoC implementation.
  • The candidate must have a strong hands-on implementation background, including physical synthesis, floorplanning, place and route, clock tree synthesis, static timing analysis, power analysis, and signoff.
  • The candidate must have demonstrated experience evaluating and optimizing power, performance, and area for high-frequency CPU cores or similarly complex designs.
  • The candidate must have a strong understanding of CPU implementation trade-offs, critical paths, physical constraints, low-power techniques, and advanced-node design challenges.
  • The candidate must be able to design controlled experiments, analyze large data sets, distinguish first-order effects from noise, and convert results into clear engineering recommendations.
  • The candidate must be proficient in scripting and automation using Python, Tcl, Perl, or similar languages.
  • The candidate must have a Bachelor's degree in Electrical Engineering, Computer Engineering, Computer Science, or a related field and 8+ years of relevant work experience; or a Master's degree in one of those fields or a related field and 7+ years of relevant work experience; or a PhD in one of those fields or a related field and 6+ years of relevant work experience.
  • The candidate must have excellent technical communication, cross-functional collaboration, and problem-solving skills.

Responsibilities

  • Lead CPU power, performance, and area (PPA) pathfinding studies for future projects, from early concept exploration through implementation feasibility assessment.
  • Define and compare PPA options across CPU microarchitecture, frequency targets, process technology, standard-cell libraries, voltage operating points, floorplans, clocking strategies, and implementation methodologies.
  • Build representative implementation experiments and design-of-experiment frameworks to quantify trade-offs and identify high-value optimization opportunities.
  • Generate area and power estimates, frequency projections, and power-performance curves across representative CPU workloads, voltage-frequency operating points, process and library options, and thermal conditions.
  • Develop constrained-performance projections under defined platform and product limits, including peak and sustained power, thermal, voltage, frequency, area, and cost constraints.
  • Evaluate iso-power, iso-performance, iso-area, and thermally constrained operating points to quantify option-level efficiency and identify competitive design points for product segments.
  • Partner with Performance, Power, Thermal, SoC, and Product teams to establish workload assumptions and system power boundaries, and translate CPU power-performance curves into sustained product-level performance projections.
  • Partner with CPU Architecture, RTL, Performance, Power, Circuits, Physical Design, CAD, Process Technology, SoC, Thermal, and Product teams to align assumptions and recommendations.
  • Drive data quality, correlation, and consistent PPA evaluation methodologies across projects, tools, and technology nodes.
  • Communicate complex trade-offs to technical leaders and partner teams, and provide recommendations that guide CPU project selection and execution.
  • Mentor engineers and contribute to scalable PPA analysis flows, automation, dashboards, and best practices.
  • Own competitive CPU PPA analysis across relevant market segments, using benchmark results, power-performance data, performance-per-area metrics, die analysis, published architecture information, and technology assumptions to identify competitive gaps and opportunities.
  • Build normalized, apples-to-apples comparisons that account for workload, operating point, process node, library, metal stack, system power boundary, thermal constraints, and measurement or modeling methodology.
  • Translate competitive insights into forward-looking PPA targets, design requirements, and differentiated implementation strategies for future CPU generations.
  • Develop viable CPU PPA options and present them to CPU Leads and CPU Product Managers, including quantified benefits, risks, assumptions, product-KPI impact, implementation complexity, schedule implications, and recommendations.
  • Partner with CPU Product Management to connect engineering trade-offs with customer priorities, market positioning, product tiers, cost constraints, sustained performance, benchmark leadership, and real-world workload efficiency.
  • Maintain a fact-based view of competitive trends and technology trajectories, and refresh recommendations as competitor data, silicon measurements, product requirements, and process assumptions evolve.

Desired Qualifications

  • Experience with CPU microarchitecture and performance analysis, including the relationship between workloads, critical paths, frequency, power, and area.
  • Experience with advanced process nodes and technology pathfinding, including standard-cell library, voltage, interconnect, and physical design trade-offs.
  • Hands-on experience with industry-standard implementation and signoff tools from Cadence and/or Synopsys.
  • Experience developing PPA estimation models, power-performance curves, design dashboards, or automated experiment frameworks.
  • Knowledge of power modeling, thermal constraints, multiple power domains, UPF-based implementation, and low-power optimization techniques.
  • Experience with pre-silicon to post-silicon PPA correlation, silicon characterization, or using measured silicon data to improve future projections.
  • Experience influencing technical direction across architecture, implementation, methodology, and product teams.
  • Experience performing competitive CPU analysis, including power-performance curves, performance per watt, performance per area, die-level analysis, or normalized product comparisons.
  • Experience presenting complex technical options and recommendations to CPU leadership, product management, or senior cross-functional decision makers.

About the Company

Qualcomm

Designs mobile chips and licenses wireless patents

Qualcomm designs the Snapdragon processors and modems inside many Android phones, and it licenses its wireless patents to device makers around the world. It helped commercialize CDMA, the cellular technology behind 3G networks, and its patents cover core parts of the 4G and 5G standards that phones use to connect. The company does not run its own chip factories; contract foundries make its chips, which it sells to makers of phones, PCs, cars, and connected devices. Device makers also pay Qualcomm royalties for using its patented technology, which forms a second business alongside chip sales. Qualcomm was founded in 1985 and is based in San Diego, California.
