Senior Mechanical Engineer – Cold Plate Design

About Corintis Corintis offers innovative microfluidic cooling technologies for AI chips/GPUs and CPUs used in data centres. Working with many of the world’s largest tech companies, our solutions improve compute sustainability and tackle the excessive electricity consumption associated with data centre cooling, which consumes more electricity than New York and London combined. Ranked as the No.1 Engineering startup in Switzerland for 2025, Corintis offers a friendly and team-oriented workplace, bringing together over 85 people from over 35 nationalities to solve the most significant computing challenges of tomorrow. Based in the EPFL Campus in St. Sulpice, we are closely connected to the local ecosystem and are located a few minutes walk from Lake Geneva. The Role We’re looking for a Senior Mechanical Engineer to lead the precision mechanical design and integration of our liquid-cooled systems for high-performance computing (HPC) and AI applications. You’ll lead the development from concept to production, with a strong focus on mechanical integrity, manufacturability, and robust design principles . Key Responsibilities: Lead the mechanical design of assemblies, fixtures, and cold plates, using Finite Elements Analysis (FEA) and applying Design for Excellence (DFX) principles. . Perform detailed tolerance analysis (GD&T) and complete robust Design Failure Mode and Effects Analysis (DFMEA). Create production-ready CAD models and technical drawings , ensuring effective revision control with PDM. Manage prototyping and production with high-quality standards, ensuring designs are manufacturable and cost-effective. Develop and validate mechanical reliability tests, including integration and structural integrity assessments. Analyze experimental data to improve mechanical robustness and production yield. Collaborate with manufacturing and supply chain teams to optimize assembly and fabrication processes. Contribute to R&D and innovation in precision mechanical integration and advanced assembly techniques. Requirements MSc or PhD in Mechanical Engineering or a closely related precision engineering field. Minimum 5+ years of industry experience in high-precision mechanical design and product development. Expert-level CAD skills , with proven experience in GD&T and advanced tolerance stacking/analysis . Strong expertise in Design for Manufacturing (DFM) and Design for Assembly (DFA). Strong expertise in Finite Elements Analysis (FEA) Understanding of relevant industry standards and quality systems. Fluent in English, with strong technical communication and problem-solving skills. Experience with metal joining techniques like brazing or advanced bonding is a strong plus. Previous experience designing liquid-cooled cold plates or microfluidic devices is a strong plus. This is a great fit if You enjoy hands-on, high-precision mechanical design, prototyping, and validation . You have expert skills in CAD, technical drawings, and advanced tolerancing (GD&T) . You are passionate about Design for Manufacturing (DFM) and optimizing mechanical processes for production. You like working in a fast-moving, collaborative startup environment. You take ownership, thrive on technical challenges, and deliver high-quality, production-ready work. This won’t be the right role if You prefer theory over practical work. You need strict, large-company processes. You don’t want to work on-site in Lausanne. You lack deep expertise or interest in precision mechanical design and tolerancing.
