Our mission is to provide a robust, scalable, and high-performance foundation for distributed serving, heterogeneous scheduling, and low-latency inference at massive scale. You will work on some of the most challenging problems in large-model online serving, spanning traffic orchestration, throughput and latency optimization, kernel efficiency, and production reliability for next-generation AI systems.\nWe are looking for talented individuals to join our team. As a graduate, you will get opportunities to pursue bold ideas, tackle complex challenges, and unlock limitless growth.\nSuccessful candidates must be able to commit to an onboarding date by the end of the year. Please state your availability and graduation date clearly in your resume.\nResponsibilities - What You'II Do\n- Build and evolve next-generation inference systems for large-scale online traffic, including global scheduling across heterogeneous compute resources, high-concurrency load balancing, and efficient batch formation\n- Optimize distributed inference for 200B+ models and complex multimodal models through TP, EP, DP, and related strategies to improve throughput and latency in production\n- Develop high-performance kernels for frontier model architectures such as MoE, emerging attention mechanisms, and multimodal fusion layers using CUDA, Triton, and related tools\n- Explore AI-driven infrastructure for inference systems, including AI Agents for kernel optimization, performance tuning, consistency validation, deployment pipelines, and intelligent operations\n任职要求 / Requirements\nMinimum Qualifications:\n- Individuals who are completing or have recently completed a PhD degree in Software Development, Computer Science, Computer Engineering, or a related technical discipline. in Computer Science, Software Engineering, Artificial Intelligence, Mathematics, or related fields\n- Familiarity with large-model architectures and strong system design skills for complex, high-concurrency environments\n- Strong understanding of asynchronous scheduling, resource pooling, and load balancing in distributed microservice systems\n- Strong engineering skills in performance optimization and production system
