The successful candidate will work on both low-level kernel optimization and system-level inference stacks, transforming theoretical ideas into efficient, production-ready code for large language models.

Responsibilities

• Create and deploy techniques to accelerate Retrieval-Augmented Generation (RAG), aiming to lower time-to-first-token and boost overall throughput.
• Build and refine pipelines for KV-cache reuse and blending, ensuring seamless integration with modern inference frameworks.
• Develop and tune sparse and selective attention mechanisms to enhance model efficiency.
• Utilize PyTorch and contemporary attention backends to profile, analyze, and optimize computational performance.
• Monitor emerging trends in open-source LLM inference, caching strategies, and RAG architectures, applying relevant advancements to internal projects.

Requirements

• Doctoral degree in Computer Science, Electrical Engineering, or a closely related discipline.
• Proficiency in Python software development, backed by extensive hands-on experience with PyTorch.
• Comprehensive knowledge of transformer inference mechanics and fundamentals.
• Proven ability to benchmark AI workloads, profile LLM execution, and identify performance constraints.
• Excellent interpersonal abilities and a collaborative mindset for working across research and engineering teams.

Nice to have

• Prior exposure to vLLM or LMCache frameworks.
• Understanding of attention kernel architectures and the ability to customize them.
• Hands-on background in constructing RAG workflows.
• Publications, technical reports, or open-source contributions related to AI systems, LLM inference, caching, or storage-aware machine learning.
• Deep systems expertise covering Linux, performance engineering, storage/IO, and memory hierarchy, with comfort operating near hardware levels.
