ByteBrain supports a wide range of infrastructure domains, including AI data center supply chains, AIOps, Operations Research and AgentOps, powering infrastructure optimization at massive scale.\nWhy This Role Is Unique\nThis role sits at the intersection of: Operations Research × AIOps × AI for Infra\nYou will have the opportunity to solve some of the most challenging optimization problems behind large-scale AI datacenters while pioneering the next generation of AI-powered decision-making systems, where LLMs, and optimization algorithms work together to improve efficiency, resource utilization, and operational intelligence across ByteDance's global infrastructure.\nResponsibilities\n- Design and develop AI, machine learning, and optimization algorithms to improve the efficiency, reliability, and performance of large-scale infrastructure systems and AI supply chain. Areas may include AIOps, operations research, software engineering, AgentOps, and system optimization.\n- Drive the deployment, scaling, and continuous improvement of algorithms in production environments, supporting large-scale services.\n- Identify optimization opportunities and emerging challenges from real-world infrastructure scenarios, translating them into impactful research and engineering solutions.\n- Conduct cutting-edge research and publish high-quality papers in top-tier conferences and journals.\nTopic Content: \nWith the large-scale adoption of LLMs and AI agents, traditional cloud-native infrastructure can no longer meet the ultra-high performance and elasticity requirements of AI workloads. This topic conducts systematic research across the entire AI infrastructure stack:\n1. Network and Observability: Research intelligent fault localization and root cause analysis for large-scale AI clusters, combined with intelligent tuning of time-series databases to improve cluster stability.\n2. Storage Systems: Develop serverless high-performance elastic file systems and storage acceleration architectures specifically for AI scenarios, explore hardware-software co-optimization for DPU, and overcome AI storage performance bottlenecks.\n3. Data Center Power Scheduling: Research GPU/CPU/MEM heterogeneous collaborative scheduling technologies, build a heterogeneous power orchestration system for AI agents, and address scheduling challenges including heterogenous workloads and state dependencies.\n4. Vector Retrieval: Optimize core vector retrieval technologies for LLM-powered applications, building a cloud-native distributed vector index engine to meet ultra-large-scale vector retrieval demands with low latency and low cost.\n5. Intelligence and Agent Architecture: Explore automatic infrastructure optimization based on AI Agent workflows, build a self-evolvable business agent framework, and enable full-stack intelligent optimization through AI for Infra. \nThis topic aims to build a next-generation AI-native infrastructure to support the deployment of LLMs and AI agents, improve resource utilization, reduce costs, support elastic scaling, and drive the technological evolution of AI infrastructure.\n任职要求 / Requirements\nMinimum Qualifications\n- Individuals who are completing or have recently completed a PhD degree in Computer Science or a related discipline. \n- Proven research track record with multiple publications in top-tier conferences or journals related to AI, machine learning, operations research, systems, or related fields.\n- Deep expertise in AI, machine learning, and/or operations research, with hands-on experience in large-scale data analysis and algorithm development.\n- Strong coding, implementation, and problem-solving skills, with the ability to bridge research and production systems.\n- Excellent communication and cross-functional collaboration skills.\nPreferred Qualifications\nIndustry experience applying AI and optimization techniques to real-world infrastructure challenges, such as:\n- AI data center supply chain optimization\n- AI Ops and intelligent operations\n- Software engineering productivity optimization\n- Operations research and resource scheduling\n- System tuning and performance optimization\n- Large-scale infrastructure management and
