Responsibilities: - Participate in the engineering development of the Volcano Ark MaaS inference system, optimizing large model inference performance, cost, and stability in ultra-large-scale heterogeneous inference clusters. - Reduce large model inference costs through system-level approaches such as disaggregated multi-role inference, distributed KV Cache systems, heterogeneous inference, elastic computing, and multi-tenant co-located inference. Qualification Minimum Qualifications: - Individuals who are completing or have recently completed a Bachelor's or Master's degree in Computer Science or a related discipline. - Strong command of algorithms, design patterns, and data structures, with solid knowledge of operating systems and computer architecture. - Proficient in one or more programming languages such as C++ or Python, with good coding style. - Understands GPU hardware architecture, is familiar with high-performance computing software stacks such as CUDA, and has experience in GPU performance analysis. - Strong interest in distributed systems and large-scale heterogeneous inference; enjoys studying low-level principles and performance bottlenecks, and actively follows progress in related fields. Preferred Qualifications: - Experience in large model inference system optimization, with practical understanding of PD disaggregation, KV Cache systems, and multi-node inference. - Experience in distributed network communication optimization, with deep understanding of distributed communication operator implementation and RDMA principles. - Familiarity with resource orchestration and scheduling frameworks such as Kubernetes and Ray.
