Power Delivery and Voltage Regulator Validation Engineer – Datacenter

## Company: Qualcomm Technologies, Inc. ## Job Area: Engineering Group, Engineering Group > Systems Engineering General Summary: 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. Overview 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. Key Responsibilities * 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. Qualifications * 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+) with appropriate probing * 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 experience (Python preferred). * Strong documentation and communication skills. * Ability to independently own validation execution and drive...
