Lead Software Engineer - Computer Graphics for the Web (WebGL/WebGPU) (F/M/D)
ABOUT THE TEAM You will join our IVION Data Foundation team, working alongside engineers across data processing, backend services, and frontend development. Together, you will make rendering faster, more scalable, and visually richer, ensuring smooth performance across different hardware environments. Beyond optimizing our existing renderer, you will shape its future architecture, influence data formats, and define performance standards. This role combines real-time computer graphics, large-scale spatial data, and web engineering, with significant ownership and room to set technical direction.
You'll be part of an open culture that values trust, collaboration, and transparency. We are proud of our environment where diverse talent can thrive and where feedback fosters individual growth and development. Do you share our passion for disruptive technology and want to be part of our dynamic journey? At NavVis, you'll own your projects, bring innovative ideas to life, and have real opportunities to grow your career and be recognized for your impact. We derive our strength from our diversity. NavVis' unwavering commitment to fostering an inclusive and diverse workplace has laid the foundation for our incredible growth. We thrive on the collective strength of our people who come from diverse backgrounds. We respect and value every experience associated with race, gender identity, sexual orientation, nationality, religion and disability.

If you need assistance at any stage of the recruiting process due to a disability, please reach out to your recruiting partner(s) for this position.
HOW YOU WILL MAKE AN IMPACT
- Own and improve browser-based 3D rendering in NavVis IVION, working with Three.js, WebGL, shaders, and rendering pipelines for point clouds, 3D Gaussian splats, meshes, and panoramic imagery
- Optimize rendering performance and visual quality through advanced occlusion culling, adaptive refinement, level-of-detail strategies, and efficient GPU memory management
- Deliver reliable rendering across different hardware environments, from high-end workstations to laptops with integrated GPUs and restricted corporate browsers
- Improve data streaming and rendering efficiency by contributing to spatial indexing, tiling, compression, caching, and progressive loading strategies
- Collaborate across the technology stack to optimize interfaces between C++ data processing, Java backend services, storage, and frontend rendering
- Shape the evolution of our rendering architecture, evaluating WebGPU, compute shaders, and modern graphics techniques to improve performance and scalability
- Strong experience in real-time 3D graphics for the web, particularly with WebGL2, Three.js, GLSL shaders, and custom rendering pipelines
- Solid knowledge of 3D mathematics and spatial algorithms, including coordinate systems, transformations, projections, spatial data structures (octrees, BVHs, KD-trees), level-of-detail, and culling techniques
- Experience rendering and streaming large-scale 3D datasets, such as point clouds, meshes, or 3D Gaussian Splats, including spatial indexing, tiling, caching, and memory management
- Strong performance optimization skills across GPU, CPU, and networking, using profiling, benchmarking, and systematic analysis to identify and resolve bottlenecks
- Proficiency in TypeScript, with experience developing and maintaining complex, performance-critical web applications
Nice to Have
- Hands-on experience with WebGPU, WGSL, or compute shaders
- Experience with C++, Rust, WebAssembly, or native graphics APIs such as Vulkan, Metal, or DirectX
- Experience with Angular, Java, or Spring Boot and working across frontend and backend systems
- Familiarity with reality capture, photogrammetry, SLAM, BIM, geospatial applications, or radiance field techniques, including 3D Gaussian Splats We offer
