United States onlyCerebras 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.
The Role
Cerebras is seeking a Network & Fiber Engineer to lead the design, deployment, and validation of high-performance network and fiber infrastructure across colocation data centers. This role is critical to enabling AI-scale compute clusters by ensuring low-latency, high-throughput connectivity between racks, data halls, and external networks. You will operate with high ownership in a fast-paced startup environment, working closely with construction, commissioning, and IT teams to bring network infrastructure online quickly and reliably.
Responsibilities
- Own end-to-end fiber and network infrastructure deployment across colo data center sites.
- Design fiber pathways, structured cabling systems, and high-density fiber distribution architectures.
- Oversee installation of fiber (SMF/MMF), patch panels, trays, and cable management systems.
- Coordinate with construction and commissioning teams to align network readiness with overall site delivery.
- Validate fiber installations including testing (OTDR, insertion loss, continuity).
- Support deployment of network hardware including switches, routers, and interconnects.
- Ensure low-latency, high-bandwidth connectivity across racks and clusters.
- Develop and maintain standards for fiber design, labeling, and documentation.
- Troubleshoot network and fiber issues during deployment and post-handover.
- Manage vendors, installers, and low-voltage contractors.
- Track progress, risks, and readiness across multiple sites.
- Coordinate with colo providers for meet-me room (MMR) connectivity and cross-connects.
- Ensure alignment on demarcation points and handoff standards.
- Manage external connectivity including ISP, dark fiber, and backbone integration.
- Validate provider fiber infrastructure and resolve interface issues.
Skills & Qualifications
- 7–12+ years of experience in network and/or fiber engineering in data centers or telecom environments.
- Strong experience with fiber design, installation, and testing (OTDR, power meter).
- Familiarity with high-density fiber systems (MPO/MTP).
- Experience deploying and troubleshooting network infrastructure.
- Understanding of data center architectures and high-performance computing environments.
- Experience working in colo environments is highly preferred.
- Ability to manage multiple concurrent deployments.
- Strong problem-solving and troubleshooting skills.
- Excellent communication and coordination abilities.
