Senior Thermal Mechanical Engineer

About Corintis: Corintis offers innovative microfluidic cooling technologies for AI chips/GPUs and CPUs used in data centers. 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. With our software platform, Glacierware, our customers or us adapt microfluidic channels to the powermap of their chip, and we manufacture these into cold plate solutions or provide solutions to enable the customer to embed these cooling channels inside the package/the chip. Working at Corintis: Corintis offers a friendly and team-oriented workplace bringing together a diverse group of over 20 nationalities to solve the biggest computing challenges of tomorrow. Based on the EPFL campus near Lausanne, we are closely connected to the local ecosystem and are located a few minutes walk from Lake Geneva. Responsibilties: Design and develop microfluidic cooling devices based on customer specifications. Utilize analytical and numerical modelling to support device design and performance optimization. Create mechanical components and assemblies for seamless integration between our product offerings and the customer requirements. Produce detailed technical drawings and oversee the manufacturing process maintaining high quality standards. Develop and implement specialized test setups to validate the cooling performance and packaging integrity of microfluidic solutions. Conduct experimental validation, including testing and data analysis, to characterize and refine prototype performance, ensuring optimal thermal and mechanical integration. Gather, analyse, and interpret data from experimental tests, using findings to inform and refine designs. Collaborate with customers to tailor solutions to specific HPC and AI platforms. Innovate advanced solutions for the mechanical integration of cooling devices into broader systems. Contribute to fundamental R&D activities within the Hardware team, fostering a collaborative environment. Research emerging technologies and trends in liquid cooling and thermal management.
