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.

What You’ll Work On

You will design and build core visualization infrastructure including:

• Real-time rendering of CAD models (STEP, BREP) using OCCT + Filament

• High-quality tessellation pipelines (curvature-aware, adaptive LOD)

• Edge and feature rendering (silhouettes, sharp edges, hidden-line removal)

• Physically-based rendering (PBR materials, lighting, shadows, SSAO)

• Handling large-scale datasets (millions of triangles / HPC outputs)

• Integration with simulation pipelines (VTK-based post-processing)

• Streaming and progressive loading of geometry

• Debugging rendering artifacts (z-fighting, precision issues, shading errors)

Key Responsibilities

• Architect and implement a production-grade CAD rendering pipeline

• Integrate OpenCASCADE geometry processing with Filament rendering

• Optimize mesh generation, GPU upload, and rendering performance

• Implement robust edge rendering and topology-aware visualization

• Solve rendering issues such as:

  • depth precision / z-fighting

  • incorrect normals / shading artifacts

  • mesh cracks and tessellation inconsistencies

• Build tooling for debugging and validating geometry pipelines

• Collaborate with simulation and backend engineers to align visualization with HPC workflows

• Contribute to code quality, performance profiling, and system design
