Senior Hardware Reliability Test Engineer – Electrical Systems & Power Electronics

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 https://openai.com/index/cerebras-partnership/ with Cerebras, to deploy 750 megawatts of scale, transforming key workloads with ultra high-speed inference. Role Summary This position develops the test capabilities and experimental evidence needed to assess the reliability of electrical hardware. You will evaluate PCB assemblies, power supplies, AC/DC and DC/DC converters, voltage regulators, and power distribution assemblies through controlled electrical and environmental testing. A central part of the role is creating practical test solutions: designing and building custom jigs and fixtures, integrating instruments and electronic loads, writing automation, and tracking performance throughout accelerated stress testing. You will work directly with the Systems team to establish realistic operating conditions and evaluate how components, boards, and power modules behave within the complete system. Electrical failure analysis is also part of the work.
