The Byte Dance DPU (Data Processing Unit) team is building the foundational computing infrastructure for Byte Dance and Volcano Engine Public Cloud. Our mission is to advance the architecture, development, and research of next-generation software-hardware technologies across compute, networking, and storage for cloud and AI computing. Our technology stack spans
- Cloud virtualization & hypervisors
- High-performance user-space network protocols (DPDK, RDMA, etc.)- High-speed interconnect and virtual switching
- Distributed storage acceleration- GPU virtualization and scheduling for AI/ML workloads

We work at the intersection of software systems, distributed infrastructure, and custom hardware acceleration, shaping the next wave of cloud-scale computing.

• Design and develop DPU network software with a focus on high performance, low latency, and reliability.
• Collaborate with hardware teams to build software-hardware co-design solutions for networking and storage acceleration.
• Explore AI/ML infrastructure acceleration, leveraging DPUs, GPUs, and custom hardware to optimize distributed training and inference.
• Drive end-to-end performance optimization, from OS kernels and drivers to user-space runtime systems.
• Contribute to architecture design, technical proposals, and long-term research directions.

We 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. Successful 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.

• Individuals who are completing or have recently completed a PhD degree in CS or a related discipline.
• Proficiency in C/C++ development and debugging.
• Familiar with Linux systems development experience.
• Solid understanding of compute, network architecture, and operating systems.
• Background in at least one of: software-hardware co-design, distributed systems, high-performance networking, or AI/ML systems.

• Experience with software-hardware co-design (networking, storage, or distributed compute).
• Hands-on experience with network virtualization (OVS, SR-IOV, eBPF).
• Familiarity with DPDK and high-performance user-space networking.
• Bonus points for hardware acceleration experience, FPGA/ASIC/GPU/CUDA-
• Bonus points for experience with NCCL Collectives along with AI communication patterns and parallelization techniques-
• Proven experience designing and building AI/ML infrastructure related but not limited to inference kv cache system, data preprocessing system.
