About The Company
The biggest challenges of our lifetime, from climate change modeling to drug discovery, constantly require more computing power. For decades, chipmakers relied on making transistors in integrated circuits smaller, and packing more of them together, to achieve more powerful and efficient chips. However, all power that goes into these billions of transistors is turned into heat. This heat needs to be extracted, as overheating causes chips to fail and lose performance. With transistors approaching the size of a few atoms, extracting this highly concentrated heat is rapidly becoming a bottleneck for the next generations of computing. In addition, cooling of chips accounts for about 30% of electricity consumption in data centers, causing an enormous environmental footprint. Sustainable and high-performance heat extraction is key to satisfy our ever-increasing demand for computational power. We are a provider of breakthrough semiconductor cooling solutions. Our solution utilizes a network of microscopically small cooling channels embedded inside the chip, which enables us to extract 10 times more heat compared to the current leading market alternatives, and extract this heat over 50x more energy efficiently. This enables the powerful integrated circuits of the future to break thermal limitations in a sustainable manner.
About the Role
<p><span>Corintis offers innovative microfluidic cooling technologies for AI chips/GPUs and CPUs used in data centers. Working with many of the world’s largest tech companies, our solutions improve compute sustainability and tackle the excessive electricity consumption associated with data center cooling, which consumes more electricity than New York and London combined.</span></p><p><span>Ranked as the No.1 Engineering startup in Switzerland for 2025, Corintis offers a friendly and team-oriented workplace, bringing together over 50 people from over 25 nationalities to solve the most significant computing challenges of tomorrow.
