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 regulation

Transient load response and droop characterization

Multi-phase VR current sharing and balancing

Thermal characterization of VR components under loadPDN 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 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…
