Cerebras Systems builds the world's largest AI chip, 56 times larger than GPUs. Our novel wafer-scale architecture provides the AI compute power of dozens of GPUs on a single chip, with the programming simplicity of a single device. This approach allows Cerebras to deliver industry-leading training and inference speeds and empowers machine learning users to effortlessly run large-scale ML applications, without the hassle of managing hundreds of GPUs or TPUs.
Cerebras' current customers include top model labs, global enterprises, and cutting-edge AI-native startups. OpenAI recently announced a multi-year partnership with Cerebras, to deploy 750 megawatts of scale, transforming key workloads with ultra high-speed inference.
Thanks to the groundbreaking wafer-scale architecture, Cerebras Inference offers the fastest Generative AI inference solution in the world, over 10 times faster than GPU-based hyperscale cloud inference services. This order of magnitude increase in speed is transforming the user experience of AI applications, unlocking real-time iteration and increasing intelligence via additional agentic computation.
- Focus on CPU and memory subsystem optimizations for our Runtime software driver, enabling faster key cloud and ML training/inference workloads across modern x86 machines that form the backbone of our AI accelerator.
- Develop and enhance algorithms for efficient data movement, local data processing, job submission, and synchronization between various software and hardware components.
- Optimize our workloads using advanced CPU features like AVX instructions, prefetch mechanisms, and cache optimization techniques.
- Perform performance profiling and characterization using tools such as AMD uprof, and reduce OS level overheads.
- Influence the design of Cerebras' next-generation AI architectures and software stack by analyzing the integration of advanced CPU features and their impact on system performance and computational efficiency.
- Engage directly with the AI and ML developer community to understand their needs and solve contemporary challenges with innovative solutions.
- Collaborate with multiple teams within Cerebras, including architecture, research, and product management, to elevate our computational platform and influence future designs.
- BS, MS, or PhD in Computer Science, Computer Engineering, or a related field.
- 5+ years of relevant experience in performance engineering, particularly in optimizing algorithms and software design.
- Strong proficiency in C/C++ and familiarity with Python or other scripting languages.
- Demonstrated experience with memory subsystem optimizations and system-level performance tuning.
- Experience with distributed systems is highly desirable, as it is crucial to optimizing the performance of our Runtime software across multiple x86 hosts.
- Familiarity with compiler technologies (e.g., LLVM, MLIR) and with PyTorch and other ML frameworks.
