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 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,
