Job description

Cerebras Systems builds the world's largest AI chip, 56 times larger than GPUs. This architecture allows Cerebras to deliver industry-leading training and inference speeds; 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. Cerebras works with the leading 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.

The Role

We are seeking an experienced Mechanical Engineer to join the Data Center Delivery organization.

• Ensure contracted mechanical scope is delivered.

Construction Support

• Perform regular site inspections.
• Monitor installation quality.
• Review contractor installation methods.
• Support schedule recovery planning.
• Validate installations against approved drawings.
