Principal Engineer, GPU Design Verification (Subsystems)

Summary Samsung, a world leader in advanced semiconductor technology, is founded on a simple philosophy – the endless pursuit of excellence will create a better world for all. At Samsung Austin Research and Development Center (SARC) and Advanced Computing Lab (ACL), we are building a center of excellence for Intellectual Property (IP) that is applied to high-performance computing devices (mobile, automotive, and other custom market segments) consumed by millions of people around the world. Come build with us! Role and Responsibilities As a Principal GPU Design Verification Engineer – Subsystems, you will lead the verification of one or more GPU subsystems for Samsung’s next-generation mobile GPU. In this high-impact and highly visible technical leadership role, you will define verification strategy and contribute hands-on to validating complex subsystem designs, ensuring functional correctness, performance integrity, and architectural intent. You bring deep expertise in GPU design verification, strong block- and subsystem-level architectural understanding, and a collaborative leadership style that aligns architecture, design, and software teams while supporting concurrent development cycles. You are a domain expert in multiple areas of subsystem-level verification. You lead verification strategy and execution for one or more GPU subsystems by developing comprehensive verification plans, defining verification goals, coverage metrics, and sign-off criteria aligned with architectural specifications and integration requirements. You excel at architecting and implementing advanced verification environments. You design, develop, and maintain scalable verification testbenches using SystemVerilog, UVM, and C++, developing test code in parallel with RTL and applying constrained-random testing, coverage-driven verification, and assertion-based techniques to validate complex block and subsystem behaviors. You elevate functional and performance excellence across subsystem coverage. You advance verification methodologies, tools, and automation to improve efficiency and quality, while creating targeted and scalable test scenarios that stress interactions across multiple blocks, interfaces, and data paths within the subsystem. You drive complex debug and issue resolution by leading team to analyze failures spanning blocks within a subsystem, identify root causes, and spearhead cross-functional collaboration to ensure verification aligns with architectural intent and system-level integration expectations. You inspire high performance by mentoring engineers, fostering a culture of ownership and innovation, and enabling mobility across blocks and subsystems to broaden technical depth and grow verification expertise.
