Corintis is seeking a Senior Graphics Engineer to lead the development of our next-generation real-time visualization pipeline for engineering and simulation workflows.
This role is focused on building high-performance CAD rendering systems combining OpenCASCADE (OCCT), Google Filament, Rust, and VTK, enabling interactive, physically-based visualization of complex engineering data at scale.
You will work at the intersection of real-time rendering, CAD geometry processing, and HPC simulation, solving challenging problems such as tessellation quality, edge rendering, depth precision, and large-scale dataset visualization.
About Corintis
Corintis is a Lausanne-based deep-tech startup developing advanced semiconductor cooling technologies to overcome one of the biggest bottlenecks in modern computing: heat dissipation.
As compute demand grows (AI, HPC, cloud), extracting heat efficiently becomes critical. Corintis enables this through microfluidic cooling embedded directly inside chips, achieving significantly higher efficiency than conventional approaches.
We are an EPFL spin-off, backed by leading investors, and ranked among the Top 100 Swiss Startups.
Working at Corintis
Corintis offers a collaborative and international environment, bringing together engineers across disciplines to solve some of the hardest problems in computing.
We are based at EPFL Innovation Park in Lausanne, minutes away from Lake Geneva, and deeply connected to one of Europe’s leading research ecosystems.
What You’ll Work On
You will design and build core visualization infrastructure including:
1. Real-time rendering of CAD models (STEP, BREP) using OCCT + Filament
2. High-quality tessellation pipelines (curvature-aware, adaptive LOD)
3. Edge and feature rendering (silhouettes, sharp edges, hidden-line removal)
4. Physically-based rendering (PBR materials, lighting, shadows, SSAO)
5. Handling large-scale datasets (millions of triangles / HPC outputs)
6. Integration with simulation pipelines (VTK-based post-processing)
7. Streaming and progressive loading of geometry
8. Debugging rendering artifacts (z-fighting, precision issues, shading errors)
Key Responsibilities
9. Architect and implement a production-grade CAD rendering pipeline
10. Integrate OpenCASCADE geometry processing with Filament rendering
11. Optimize mesh generation, GPU upload, and rendering performance
12. Implement robust edge rendering and topology-aware visualization
13. Solve rendering issues such as:
depth precision / z-fighting

mesh cracks and tessellation inconsistencies
14. Build tooling for debugging and validating geometry pipelines
15. Collaborate with simulation and backend engineers to align visualization with HPC workflows
16. Contribute to code quality, performance profiling, and system design
