Senior UI​/UX Designer

About Corintis

Corintis is a startup that is a provider of advanced semiconductor cooling technologies. Some of the biggest challenges of our lifetime, from climate modelling to drug discovery, constantly require more computing power. More powerful chips generate more heat; extracting this heat is a major challenge for our future.

Current cooling systems are not only limited but also wasteful; cooling data centers consume more power than London and New York combined. At Corintis, we remove these limitations by integrating cooling directly inside the chip. We enable the sustainable computing of the future to address the biggest global challenges.

Corintis offers a friendly and team-oriented workplace bringing together a diverse group of 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.

We're looking for a Senior UI/UX Designer who thrives in technical environments and enjoys translating complex engineering workflows into intuitive, beautiful, and scalable interfaces. You will own design end-to-end scientific/3D tools, from early concepting and UX flow architecture to final visual polish and brand consistency across all channels.

• Design UI/UX for engineering tools involving CFD simulations, 3D scientific visualization, and CAD model interaction.
• Create user flows, wireframes, high-fidelity mockups, and component libraries.
• Collaborate with engineering teams to understand scientific requirements and convert them into usable interfaces.
• Help define the design language for complex data visualization (3D, color maps, simulation results).
• Mentor engineers on design thinking and usability principles.

• 5+ years of experience in UI/UX design, with strong visual design and branding expertise.
• A strong portfolio demonstrating clarity, aesthetic quality, and ability to handle technically complex products.
• Experience with scientific, engineering, 3D, or data-heavy tools (CFD, CAD, simulation platforms, scientific visualization).
• Background in engineering, physics, computational design, or scientific visualization.
• Excellent ability to simplify complex information into intuitive visual narratives.
• Comfortable working with a software development team.
• Proactive mindset: you enjoy driving design initiatives and owning the creative direction.

• The chance to shape the design language of a deep-tech company with global impact.
• Ownership and autonomy-your work will directly influence the product and brand.
• Collaboration with top engineers and researchers in HPC and microelectronics.
• A high-growth, innovation-driven environment where design truly matters.

• You enjoy designing for technical users (engineers/researchers) and get energy from turning complex, domain-heavy workflows into clear, low-friction UX.
• You can think in systems: you like building scalable component libraries, design tokens, and patterns that engineers can reliably implement.
• You’re comfortable shaping ambiguity early: you can drive discovery, map workflows, define information architecture, and validate concepts before polishing UI.
• You collaborate tightly with engineering: you’re fluent in constraints (performance, WebGL/3D pipelines, implementation tradeoffs) and can keep design intent intact through delivery.

• You prefer marketing-only or brand-only design and don’t want to spend time deep in product UX, domain constraints, and complex tool behavior.
• You dislike iterative feedback loops with engineers and users, and would rather hand off mockups without ongoing collaboration through implementation.
• You’re not comfortable with technical complexity (CFD concepts, 3D interaction paradigms, data density) and find it draining to learn new scientific workflows.
• You rely heavily on heavy-handed visuals instead of clarity and usability—this product needs precision, not decoration.
