Job Title: Principal engineer, AI Serving Framework Architect (Software)

What You’ll Do

The Architecture Research Lab (ARL) focuses on addressing fundamental system‑level bottlenecks in modern AI, particularly in memory capacity/bandwidth and system‑scale communication. By leveraging Samsung’s world‑class memory technologies, ARL explores and defines next‑generation AI system architectures that deliver step‑function improvements in performance, efficiency, and scalability.

We are seeking a Principal AI System Architect who will play a key role in bridging AI workloads, system architecture, and hardware design. In this role, you will develop system‑level performance models, drive architecture‑level design decisions, and propose forward‑looking AI system architectures that shape Samsung’s long‑term AI platform strategy.

Responsibilities

• Lead research teams in Korea and propose technical direction as a Tech Lead.
• Research dynamic scheduling methodologies for maximizing AI inference performance in multi‑rack scale memory‑centric systems composed of heterogeneous compute‑capable memory and hierarchical memory.
• Investigate methods to accelerate search operations in RAG’s vector DB and AI Agent’s knowledge‑graph by leveraging compute‑capable memory.
• Study strategies for optimally placing KVCache and a vector DB in hierarchical memory to minimize frequent SSD accesses and reduce IO stalls.
• Propose SW design for implementing the derived optimization algorithms on open‑source platforms such as vLLM.

What You Bring

• PhD in Computer Science or a related field with 15+ years of experience in AI Serving Framework for large‑scale computing, focusing on AI workloads.
• Led a project to build and optimize a Large Language Model (LLM) inference software stack on a multi‑rack scale system delivering AI inference services to over 100,000 users.
• Extensive experience designing AI inference software stacks for heterogeneous devices.
• In‑depth understanding of the internal architecture and operation mechanisms of inference engines such as vLLM.
• Proficiency in AI inference system profiling and optimization.
• Knowledge and practical experience with future AI workloads, including reasoning models, multi‑modal solutions, AI agents, and world models.
• Strong understanding of compute, memory, and networking bottlenecks in AI systems.
• Required skillsets: PyTorch, Python, and C++.
• A collaborative mindset, curiosity, and resilience in solving complex challenges.
• Excellent verbal, presentation, and written communication skills.
• (Nice to have) Native or fluent Korean speakers are preferred.
• Inclusive, adaptable to diverse global norms and situations.
• Approach challenges with curiosity and resilience, seeking data to build solutions.
• Innovative and creative, proactively exploring new ideas and adapting quickly to change.
