3D editor

About the Role

We are looking for a software engineer to join the 3D tools development team to work on a browser-based 3D map editing application used to view and edit geospatial features including road networks, buildings, lidar point clouds, and imagery. You will work on a rich, interactive application that combines real-time 3D rendering, complex data modeling, and precision editing tools.

Responsibilities

Develop and maintain features across the full application stack — from data loading and editing operations to 3D rendering and UI

Implement undoable editing operations for geospatial features with real-time validation

Build interactive tools for editing map features in a 3D viewport

Optimize rendering performance for large-scale geospatial datasets

Write unit tests and maintain code quality through code review

Collaborate with data engineers, cartographers, and product stakeholders

Required Skills

Experience : 2+years

JavaScript & Web Platform

Strong proficiency in modern JavaScript (ES modules, classes, iterators, async patterns)

Experience with browser APIs (DOM, Canvas, Web Workers, WebGL)

Familiarity with build tools such as Vite or Webpack

3D Graphics

Experience with Three.js or similar WebGL frameworks

Understanding of scene graphs, cameras, projections, and coordinate systems

Comfort with matrix/vector math and spatial transformations

Software Design

Experience with, and enthusiasm for designing and maintaining a moderately large JavaScript codebase without a framework (no React/Angular/Vue)

Familiarity with patterns such as pub/sub, undo/redo, and MVC

Ability to write clean, well-structured code with clear module boundaries

Testing & Quality

Experience writing unit tests (we use Vitest)

Familiarity with type checking via JSDoc annotations and TypeScript tooling (checkJs)

Preferred Skills

Geospatial knowledge — coordinate reference systems (WGS84, Mercator), map projections, geographic data formats

Computational geometry — curves (NURBS, Bezier), triangulation, spatial indexing

C++/WASM — we use Emscripten to compile performance-critical C++ code to WebAssembly

Git — comfortable with branching workflows, rebasing, and merge conflict resolution

UI development — experience building custom UI components (we use Bootstrap 5, no component framework)

AI – comfort using AI coding assistants (Claude Code, GitHub Copilot, Kiro, etc.)

Experience with -- web security, authentication, package publishing, privacy, AWS / Cloudflare, performance optimization and browser based debugging
