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, OCPVR efficiency curves and load regulationTransient load response and droop characterizationMulti-phase VR current sharing and balancingThermal characterization of VR components under loadPDN impedance measurementsTelemetry 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 probingEloads, Bench suppliesDifferential probes and current probesPMBus/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. Preferred Qualifications • 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 high-current, fast-transient power delivery requirements • Experience with open compute / hyperscale server power delivery architectures (e.g., OCP, CRPS, ORv3) • Familiarity with VR co-design processes and feedback into hardware design teams • Experience supporting manufacturing, factory, or field escalations. Minimum Qualifications: • Bachelor's degree in Engineering, Information Systems, Computer Science, or related field and 6+ years of Systems Engineering or related work experience. OR Master's degree in Engineering, Information Systems, Computer Science, or related field and 5+ years of Systems Engineering or related work experience. OR PhD in Engineering, Information Systems, Computer Science, or related field and 4+ years of Systems Engineering or related work experience. Qualcomm is an equal opportunity employer.
