About The Position

The Language & Personal Intelligence (LPI) Lab at Samsung Research America focuses on advancing next-generation AI systems that understand, reason, remember, and adapt to users over time. Our mission is to build deeply personalized, context-aware, and agentic intelligence that operates efficiently across devices and ecosystems, combining foundational research with real-world impact at global scale. We are looking for a Senior Staff AI Research Engineer to design, prototype, and advance AI systems for language intelligence, personalization, and adaptive reasoning. This role sits at the intersection of research and engineering, contributing to both exploratory research and scalable implementations, with an emphasis on efficient and privacy-aware on-device AI. Opportunity to work on next-generation personalized and agentic AI systems with real-world impact A collaborative environment that values both research depth and practical engineering excellence

Requirements

• PhD in Computer Science, Artificial Intelligence, Machine Learning, Natural Language Processing, or a related field, or equivalent industry research experience
• 7+ years of experience in AI research, applied research, or advanced AI engineering
• Strong experience with modern ML frameworks (e.g., PyTorch, TensorFlow, JAX)
• Solid understanding of language models, retrieval-based systems, or knowledge-augmented AI
• Experience designing and implementing end-to-end AI systems, from modeling to evaluation
• Strong problem-solving skills and ability to work effectively in research-driven engineering environments

Responsibilities

• Design and implement AI models and systems for language understanding, generation, and personalization
