Job Description:WHAT YOU DO AT AMD CHANGES EVERYTHINGAt AMD, our mission is to build great products that accelerate next-generation computing experiences—from AI and data centers, to PCs, gaming and embedded systems. Grounded in a culture of innovation and collaboration, we believe real progress comes from bold ideas, human ingenuity and a shared passion to create something extraordinary. When you join AMD, you’ll discover the real differentiator is our culture. We push the limits of innovation to solve the world’s most important challenges—striving for execution excellence, while being direct, humble, collaborative, and inclusive of diverse perspectives. Join us as we shape the future of AI and beyond. Together, we advance your career.THE ROLE:Technical, hands-on engineer responsible to ensure the processor/SoC meets its required operating frequencies at the lowest safe supply voltages by defining, validating, tuning and maintaining the Vmin (voltage-vs-frequency) curves and associated protection/attainment mechanisms.KEY RESPONSIBILITIES:
  • Derive and maintain Vmin vs. frequency curves and voltage/frequency (V/F) characterization across process corners, temperatures and aging; incorporate PVT and per-core/cluster binning into static tables and/or online calibration.
  • Implement, tune and validate frequency attainment mechanisms (Vmin tuning algorithms, adaptive voltage scaling, SVID/PMIC controls, fmax governors) to reliably reach target frequencies without functional failures.
  • Plan and execute silicon bring-up and lab validation: ring/logic/GPU stress tests, frequency and voltage sweeps, margining, jitter and timing closure verification across PVT corners.
  • Characterize transient and steady-state voltage requirements, set ramp rates, slew limits and decoupling recommendations with PMIC/PD teams to prevent droops during frequency switches and DVFS events.
  • Define and run automated stability and regression suites (workloads, power-stage transients, fast frequency scaling) to detect undervoltage faults, brownouts and performance regressions.
  • Develop and validate safe operating points, watchdogs and fallback strategies (hold states, throttling, core isolation) to protect hardware when Vmin or other limits are violated.
  • Perform failure analysis and root-cause debugging for frequency attainment and stability issues using telemetry, logs, silicon probes and logic analyzers (timing violations, crashes, ECC events).
  • Account for variability and telemetry: temperature sensors, aging compensation, per-core/cluster calibration, and adapt Vmin/runtime policies accordingly.
  • Collaborate cross-functionally with silicon validation, firmware/bootloader, PMIC/PMU, power delivery and system software to integrate Vmin tables, calibration data and runtime tuning hooks into firmware and OS power managers.
  • Support prototyping and experiments for features affecting GPU/APU and system-level power/performance; exploit architecture bottlenecks to test and mitigate worst-case scenarios.
  • Characterize product KPIs and analyze characterization data for process variation to inform product definition and next-generation design trade-offs.
  • Troubleshoot system-level issues on test and customer platforms, drive continuous improvement for post-silicon power/performance activities, and participate in product definition reviews and launch handover Document Vmin methodology, calibration procedures, limits, release notes and provide operational guidance for manufacturing test, bring-up and field support.
PREFERRED EXPERIENCE:
  • Excellent grasp of computer organization/architecture
  • Strong understanding of transistor operation and physics
  • Strong programming skills, experience in Python preferred
  • Desirable to be proficient in Linux command line environment and Shell scripting
  • Deep knowledge of power management techniques like deep sleep and clock gating
  • Strong analytical and problem-solving skills with a key attention to detail
  • Excellent presentation and communication skills
  • Proficient in using lab equipment like oscilloscopes and power supplies
ACADEMIC CREDENTIALS:
  • BS degree in Electronics/Computer Engineering or Computer Science with emphasis on computer architecture and workload analysis, MS preferred
