Project Overview:
On this project we develop a system that allows visualization of road network data. The main goal is to transform raw GIS map data into visually correct and attractive roads that can be rendered in modern graphics engines.
Raw map data often contains geometry issues, noisy coordinates, and topology inconsistencies. Our system processes these datasets and prepares them for visualization by applying geometry correction, smoothing algorithms, and mesh generation. As a result, roads look natural and visually consistent for the end user while preserving spatial accuracy.
The platform includes backend services and distributed data processing pipelines that transform raw geospatial sources into rendering-ready artifacts and map tiles.
The processed data is used for navigation products, map analysis tools, and visualization systems.
We need a rendering engineer to rapidly prototype browser-based lane visualisation using spline geometry — making it look great and run fast.
Requirements:
* 7+ years of experience in software engineering, including at least 4 years in rendering / graphics development
* Strong TypeScript expertise
* Rendering / computer graphics experience
* WebGL experience, ideally WebGPU
* Experience with three.Js, Babylon. xhfqzwm js, or MapLibre GL JS
* Spline / curve-based geometry generation experience
* Shader authoring (GLSL / WGSL)
* GPU rendering optimisation
* Performance profiling and bottleneck analysis
* Efficient data structures for rendering and geometry processing
* Understanding of vector map data, tile formats, and feature encoding
* Visual effects knowledge: anti-aliasing, blending, post-processing, lighting
Nice to have:
* Geospatial / navigation / lane-guidance visualisation experience
* Experience with HD lane data
Responsibilities:
* Prototype browser-based lane visualisation using spline geometry
* Turn noisy lane data into smooth, visually convincing rendered output
* Optimise GPU rendering performance for large-scale vector map data
* Profile and benchmark browser rendering performance
* Improve rendering quality and spatial accuracy of lane geometry
* Evaluate rendering approaches through rapid visual experimentation
* Collaborate with map data engineers on rendering compatibility
* Debug geometry, topology, and rendering artefacts.
