Client is seeking an experienced Power & Interface IC Supply Chain R&D Engineer to serve as the technical owner of our power management and interface IC supply base. Key Responsibilities Supplier Technical Management Develop, qualify, and manage a base of power and interface IC suppliers and their OSAT partners to ensure technical capacity, quality, and reliability targets are met. Establish and maintain technical supplier scorecards tracking OTD, quality (PPM/DPPM), yield, reliability, and responsiveness. Drive continuous-improvement initiatives with strategic suppliers and OSATs to improve yield and cycle time. Manage dual-source and second-source strategies to mitigate single-source risk and ensure component supply resilience. New Product Introduction (NPI) Coordinate technical reviews between Client hardware/package design teams and supplier applications and process teams; manage device selection, process/technology, and package/revision trade-offs against reliability, yield, and schedule. Quality, Reliability, and Continuous Improvement Partner with Supplier Quality Engineering on power and interface IC excursions: containment, 8D root-cause analysis, corrective actions, and re-qualification with supplier and OSAT process teams. Champion DFM and design-for-reliability feedback loops between suppliers/OSATs and Client hardware and package design teams. Cross-Functional Leadership Represent power and interface IC supply chain in NPI program reviews. Interface routinely with Hardware Design Engineering, Signal/Power Integrity, Package Engineering, IC suppliers (e.g., PMIC and interface-IC vendors), OSATs (ASE, Amkor, Powertech, SPIL), Quality, Logistics, and SK hynix counterparts. Serve as Client escalation lead for power and interface IC supply issues, bridging U.S. design/operations stakeholders with Asia-based suppliers and OSAT partners across time zones and cultural contexts. Required Qualifications Education: Bachelor's degree in Electrical Engineering, Materials Science, Physics, or a related technical field. Experience: 5+ years in semiconductor supply chain R&D, component/product engineering, or hardware/reliability engineering, with at least 2 years of direct exposure to power management or interface/analog-mixed-signal IC sourcing or qualification. Technical knowledge: Analog and mixed-signal IC technology; power delivery and PMIC/regulator fundamentals; high-speed interface signaling (e.g., PCIe/NVMe re-timers, re-drivers, level shifters) and signal/power integrity. Nice to have understanding of component qualification and reliability methods (HTOL, HAST/uHAST, temperature cycling, ESD/latch-up, JEDEC reliability). Assembly/test knowledge: Familiarity with OSAT assembly and final-test flow and how process and test quality impact downstream yield and field reliability. Communication: Able to present supply risk and recommendations clearly to senior leadership and to coordinate effectively with international suppliers across time zones. Remote effectiveness: Demonstrated ability to work independently and stay aligned in a distributed, remote environment. Work authorization: Must be legally authorized to work in the United States without sponsorship. Preferred Qualifications Master's degree in Engineering (electrical, materials, or related field). Direct experience with PMICs, voltage regulators, load switches, level shifters, re-timers/re-drivers, or other power and interface ICs used in storage, server, or networking hardware. Established working relationships with tier-1 power and interface IC suppliers and OSATs in the U.S., Taiwan, Korea, or Japan. Familiarity with Client product families and SSD hardware/power architecture requirements. Six Sigma Green/Black Belt certification. Conversational Mandarin, Japanese, or Korean - a plus for engagement with Asia-based suppliers and OSAT partners.
