Senior Staff Engineer, GPU Design Verification (Subsystems)

Position Summary

Samsung, a world leader in advanced semiconductor technology, is seeking a Senior Staff GPU Design Verification Engineer – Subsystems to join the GPU Design Verification team at SARC/ACL. This role involves shaping the verification of one or more GPU subsystems for Samsung’s next-generation mobile GPU, contributing to the verification strategy, and hands-on validation of complex subsystem designs.

Role And Responsibilities

• Contribute to the 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.
• Leverage expertise in one or more technical areas to architect and implement advanced verification environments, 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.
• Ensure functional and performance excellence across subsystem coverage by advancing 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.
• Drive complex debug and issue resolution by analyzing failures spanning blocks within a subsystem, identifying root causes, and collaborating with design and architecture teams to ensure verification aligns with architectural intent and system-level integration expectations.
• Mentor engineers, exemplify a culture of ownership and innovation, and stay ahead of emerging verification technologies and methodologies.

Skills And Qualifications

• 10+ years of experience with a Bachelor’s Degree in Computer Science/Engineering, or 8+ years of experience with a Master’s Degree, or 6+ years of experience with a Ph.D.
• 8+ years of hands-on experience in GPU, CPU, or advanced semiconductor design verification.
• Strong understanding of computer architecture and GPU subsystem design, including block-level and subsystem-level integration.
• Strong programming skills in C/C++, Python, Perl, or equivalent.
• Strong expertise in SystemVerilog and UVM, including constrained-random testing, functional coverage, and assertions.
• Experience with building configurable UVM testbenches for reuse across design hierarchies, ensuring a block-level environment can seamlessly transition into a system-level environment.
• Proven track record of achieving multiple first-pass silicon success.
• Experience with contributing to verification strategy and execution for multiple subsystem blocks and verification closure across interfaces.
• Excellent debugging, analytical, and problem-solving skills, with proven ability to identify bottlenecks, propose solutions, and execute implementation.
• Excellent communication and collaboration skills, with the ability to navigate ambiguity and influence in a fast-paced, global team environment.

Nice to have

• Knowledge of memory subsystem or coherent interconnects.
• Experience with performance-aware verification or performance profiling.
• Hardware modeling or emulation experience.
• Demonstrated passion for learning modern graphics architectures and evolving GPU technologies.
