Team Introduction The Applied Research Center at ByteDance is a team dedicated to cutting-edge infrastructure system innovations, including but not limited to compute, storage, database, and networking. We are looking for experienced engineers and researchers in both the infra for AI and AI for infra areas, to help us build hyper scale cloud infrastructure and foundational platforms to drive next-gen ML systems and applications. Infra for AI As a software researcher/engineer in this team, you’ll work on the fundamental infrastructure components that all other teams at ByteDance build upon, such as our compute platform, storage, database, and networking stack. As new AI/ML workloads are emerging around the world, designing and building next-gen cloud computing and machine learning infrastructure to enable cost-efficient and easy-to-use ML solutions based on Valcano Engine, ByteDance’s public cloud offering, is our team’s primary focus. You will work closely with other teams and business units to seamlessly integrate new ML platforms into the current cloud infrastructure and build the foundation for Valcano Engine’s technical and business growth. Responsibilities: - Design, architect and implement next-gen cloud computing and ML infrastructure to enable cost-efficient, easy-to-use and secure ML platforms that reduce time-to-market (TTM) for ByteDance customers. - Collaborate with other teams and business units to seamlessly integrate new ML platforms into the current cloud infrastructure. - Write high quality, product level code that is easy to maintain and test. - Optimize existing cloud systems/services to improve performance and efficiency. - Keep up with the latest state-of-the-art in the open source and the research community in AI/ML, LLM and systems, and implementing and extending best practices. - Write papers and patent applications. AI for Infra ByteBrain is a platform that provides AI services for infrastructure. The goal is to automatically optimize system performance and reduce labor and resource costs. ByteBrain integrates machine learning and AI techniques to serve all infrastructure systems in Bytedance as well as public cloud. Responsibilities and Duties: - Explore and implement state-of-the-art methods in the field of AI/LLM for infrastructure. - The topics include but are not limited to AI/LLM for Ops, AI/LLM for DB/OS/Storage/networking, LLM Agent, RAG, LLM Finetuning, AI-based Optimization. - Collaborate with current and potential teams and BUs to explore more business and research directions and impact. - Write high quality papers and patent applications Minimum Qualifications: - B.S./M.S/Ph.D, degree in Computer Science, Computer Engineering or a related area with 3+ years of relevant industry experience; new graduates with Ph.D. degree and strong publication records can be an exception. - Solid understanding of at least one of the following fields: - AI/LLM for Ops, AI/LLM for DB/OS/Storage/networking, LLM Agent, RAG, LLM Fintuning, AI-based Optimization - Parallel file systems (Lustre, GPFS, BeeGFS, DAOs), high-performance storage systems (e.g., HDFS), distributed key-value storage engine and cache systems etc - Cloud computing systems and Serverless computing - Cloud database and data management systems - High-performance networking (experience with RDMA, DPDK, or protocol design is a bonus) - GPU, CUDA,Pytorch/Triton,Heterogeneous computing,CXL,UALink - Proven experience designing, architecting and building cloud and ML infrastructure - Proficiency in at least one major programming language such as Python, Go, C++, and Java. Preferred Qualifications - Experience with container and orchestration technologies such as Docker and Kubernetes., Ray, ML framework such as Pytorch, vLLM and TensorFlow, Resource management and allocation, Job scheduling and monitoring. - Experience working on storage and data processing systems, GPU-direct storage in AI/ML training and inference framework. - Experience working on GPUs/CUDA and/or LLM engines (e.g., vLLM, TensorRT-LLM). - Experience with a public cloud provider (AWS, Azure and GCP), and their ML services (e.g., AWS SageMaker, Azure ML, GCP Vertex AI, AWS Q). - Experience with database kernel development, Vector database, Autonomous database, Trusted database, RAG, Data platform for ML/LLM - Proficiency in Algorithms/AI/LLM, ML systems (e.g., Ray, DeepSpeed), and deep learning frameworks (e.g., PyTorch). - Strong publications in top conferences in related areas. - Great communication skills and the ability to work well within a team and across engineering teams. - Passionate about system/AI efficiency, quality, performance and scalability.
