Principal System Engineer

About the role

The Principal System Engineer/Product Definer in our Power Management Group will define the next generation of processor core (VCORE) power solutions for laptops and Edge AI platforms, ensuring full compliance with industry standards.

Responsibilities

• Collaborate directly with laptop OEMs/ODMs and compute-silicon vendors (Intel, AMD, and Edge AI/GPU silicon partners) to translate platform power requirements, IMVP/SVI compliance targets, RFI into Engineering Requirements Specifications with architectural and electrical specifications for the VCORE, VCCSA/SoC and GT/NPU rails.
• Conduct topology identification, phase-count optimization, and detailed efficiency studies for multiphase buck / SPS (Smart Power Stage / DrMOS) core-rail architectures using system-level simulation tools (e.g., SIMPLIS, MATLAB, or similar).
• Develop high-fidelity behavioral models to evaluate architectural trade-offs, Adaptive Voltage Positioning (AVP) load-line, DVID/dynamic-VID transients, and loop stability against Intel IMVP and AMD SVI transient and light-load (phase-shedding) requirements.
• Review and update system models based on PCB schematics and layouts to account for real-world PDN parasitics (ESL/ESR) and the “last-inch” interconnect that constrains transient performance in dense laptop and Edge AI boards.
• Lead cross-functional teams (Design, Marketing, Applications) during architecture reviews, silicon-vendor compliance reviews, and platform bring-up. Collaborate closely with IC Design teams to identify the optimal controller + power-stage partitioning and the SVID/PMBus digital feature set required to meet complex IMVP/SVI system specifications.
• Identify long-term value-creation avenues in Edge AI/NPU core power, high-current vertical power delivery, and next-generation IMVP/SVI feature adoption to keep the roadmap ahead of rising SoC currents and tightening efficiency targets.
• Act as the final technical escalation point for customers, using structured methods, system knowledge and experience to resolve complex system issues.

Qualifications

• Education: BS/MS in Electrical Engineering (Power Electronics emphasis preferred); PhD is a plus.
• Experience: Minimum 12 years of semiconductor experience, with a focus on multiphase DC-DC converters and processor core-rail (VCORE) regulation for laptop and/or Edge AI platforms. Hands-on product-definition experience with Intel IMVP-compliant and/or AMD SVI2/SVI3 VR solutions is strongly preferred.
• Technical Skills: Proficiency in system design and simulation tools such as SIMPLIS/SIMetrix, MATLAB, or Cadence-based environments for multiphase VR modeling. Deep knowledge of Power Delivery Networks (PDN), PCB parasitics, multiphase control (AVP/load-line, current balancing, phase shedding), and serial-VID interfaces (Intel SVID, AMD SVI2/SVI3, PMBus). Proficiency in Python or C for behavioral modeling and task automation.
• Communication: Proven track record of interfacing with OEM’s or Intel/Amd technical leadership.
• Bonus (a Big Plus): Familiarity with NVIDIA OpenVReg (OVR) specifications (e.g., OVR4-22, OVR16) and PWMVID-based multiphase core power for GPU / Edge AI platforms is a strong differentiator.
