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.

About the Role

~1 min read

Join the inference model team dedicated to bring up the state-of-the-art models, numerically validating and accelerating new model ideas on wafer-scale hardware. You will prototype architectural tweaks, build performance-eval pipelines, and turn hard numbers into changes that land in production.

Responsibilities

→Prototype and benchmark cutting-edge ideas: new attentions, MoE, speculative decoding, and many more innovations as they emerge.
→Develop agent-driven automation that designs experiments, schedules runs, triages regressions, and drafts pull-requests.
→Work closely with compiler, runtime, and silicon teams: unique opportunity to experience the full stack of software/hardware innovation.
→Keep pace with the latest open- and closed-source models; run them first on wafer scale to expose new optimization opportunities.

Requirements

~1 min read

3 + years building high-performance ML or systems software.
Solid grounding in Transformer math—attention scaling, KV-cache, quantisation—or clear evidence you learn this material rapidly.
Comfort navigating the full AI toolchain: Python modeling code, compiler IRs, performance profiling, etc.
Strong debugging skills across performance, numerical accuracy, and runtime integration.
Prior experience in modeling, compilers or crafting benchmarks or performance studies; not just black-box QA tests.
Strong passion to leverage AI agents or workflow orchestration tools to boost personal productivity.

Hands-on with flash-attention, Triton kernels, linear-attention, or sparsity research.
Performance-tuning experience on custom silicon, GPUs, or FPGAs.
Proficiency in C/C++ programming and experience with low-level optimization.
Proven experience in compiler development, particularly with LLVM and/or MLIR.
Publications, repos, or blog posts dissecting model speed-ups.
Contributions to open-source agent frameworks.
