Our Mission:
We are dedicated to transforming the industry by reimagining silicon and developing next-generation computing platforms. By joining our team, you’ll collaborate with world-class engineers to create innovative solutions that push the limits of performance, energy efficiency, and scalability. Our focus is on developing reference platforms based on Qualcomm's Snapdragon SoC, delivering a comprehensive solution that includes hardware, software, reference designs, user guides, SDKs, and more.

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 is a hands‑on, high‑ownership role 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.
• Validate VR efficiency curves and load regulation.
• Validate transient load response and droop characterization.
• Validate multi‑phase VR current sharing and balancing.
• Validate thermal characterization of VR components under load.
• Validate PDN impedance measurements.
• Validate 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 (1GHz+);
  Eloads, 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…
