We are seeking a Staff or Sr. Staff Power Delivery and VR Validation Engineer (individual contributor) with deep expertise in voltage regulator characterization, PDN validation, and power integrity lab measurements. This hands‑on, high‑ownership role is responsible for ensuring robust, efficient, and reliable power delivery on server‑class platforms based on Qualcomm's Snapdragon SoC — from first power‑on through production readiness.

• Lead power delivery bring‑up from first power‑on, including rail sequencing verification, VR enable/disable, and initial PDN health checks.
• Define and own the end‑to‑end VR and PDN validation strategy and test plans from EVT through PVT.
• Validate:
  • VRs, Power rails, sequencing, margining, and VR control loops stability, OCP.
  • VR efficiency curves and load regulation.
  • Transient load response and droop characterization.
  • Multi‑phase VR current sharing and balancing.
  • Thermal characterization of VR components under load.
  • PDN impedance measurements.
  • Telemetry and interfaces (PMBUS/AVSBUS).
• Perform hands‑on debug of power delivery issues including rail failures, sequencing faults, VR anomalies, and PDN resonance issues.
• Drive root‑cause analysis and validation of fixes.
• Develop or maintain automation tools/scripts (Python, Shell, TCL) for VR testing automation.
• Support DVT/PVT, factory bring‑up, board re‑spins, and field issues.
• Support IR Drop, AC, and transient simulations as needed, and provide model‑to‑hardware correlation data to the PI simulation team.
• Contribute to VR design reviews, component selection, and design‑for‑validation (DFV) feedback to hardware design teams.
• Establish and maintain power delivery lab infrastructure, test fixtures, and measurement methodologies for VR and PDN characterization.
• Generate and present validation reports, bring‑up guides, and debug documentation to stakeholders including engineering teams, senior management, customers, and suppliers.
• Identify power delivery risks early in the design cycle and drive mitigation strategies in collaboration with hardware and PI simulation teams.

• Bachelor’s degree in Electrical Engineering, Computer Engineering, or related field.
• 8+ years of experience in board or platform hardware validation. Sr. Staff designation requires demonstrated broader scope, including ownership of multi‑platform validation strategy or team technical leadership.
• Hands‑on experience with power delivery/power integrity in server‑class or high‑performance platforms.
• Strong understanding of power sequencing and board‑level debug.
• Strong hands‑on experience validating multi‑phase voltage regulators, including control loop stability, efficiency, transient response, and PDN characterization.
• Proficiency with lab equipment:
  • High‑bandwidth oscilloscopes (1 GHz+) with appropriate probing.
  • E‑loads, bench supplies.
  • Differential probes and current probes.
  • PMBus/SMBus interface tools.
• Understanding of VR topologies (e.g., buck, multi‑phase) and control modes (CCM, DCM, AVP).
• Familiarity with PMBus/AVSBus protocols and VR telemetry interfaces.
• Automation and scripting experience (Python preferred).
• Strong documentation and communication skills.
• Ability to independently own validation execution and drive cross‑functional alignment on power delivery readiness.

• Master’s degree in Electrical or Computer Engineering.
• 10+ years of platform power bring‑up or validation experience.
• Experience with PI simulation tools (e.g., Simplis/Simetrix, ANSYS SIwave) for model‑to‑hardware correlation.
• Familiarity with 2.5D/3D packaging technologies and their impact on power delivery.
• Experience with AI/ML compute platforms and their…
