3D Graphics Engineer (Three.js / WebGL)

• Build diagnostics and debug tooling that keep visual quality and performance measurable.

Collaboration

• Partner with full stack and web developers to expose clean, well-documented renderer APIs to the web app.

• Work with 3D-capture, content, and design teams to bring real spaces and designs into the engine.

• Contribute to the Nx monorepo with strong testing, code review, and documentation.

• Help define the technical direction of immersive and photoreal experiences.

Our Stack

Core (what you will work in daily)

• A custom Three.js rendering engine (@imerza/threejs-renderer) built on React Three Fiber and drei, mounted inside a Next.js app.

• Gaussian splatting via Spark (@sparkjsdev/spark) for photoreal capture of real-world spaces, rendered alongside traditional mesh-based content.

• glTF and GLB asset pipelines with Draco compression, KTX2 and Basis textures, baked lightmaps, and HDR image-based lighting.

• WebGL and GLSL shaders, post-processing (temporal anti-aliasing, ambient occlusion), and spatial acceleration with three-mesh-bvh.

• WebXR immersive viewing via @react-three/xr, including a 360 viewer.

• TypeScript throughout, in an Nx monorepo with pnpm workspaces.

Adjacent areas (owned by other engineers; good to understand)

• The React and Next.js plus Payload CMS web app that hosts and configures the renderer.

• Real-time digital-twin data streamed into scenes over MQTT.

• AWS (CDK) and Docker-based on-prem deployments.

Skills, Knowledge and Expertise

• 3 to 7+ years of professional software engineering experience, with significant time spent on real-time 3D or graphics.

• Deep proficiency with Three.js (React Three Fiber experience is a strong plus).

• Solid WebGL and GLSL shader experience.

• Strong TypeScript or JavaScript skills.

• Experience with 3D asset formats and pipelines (glTF and GLB, textures, compression).

• A strong grasp of 3D math (vectors, matrices, quaternions, transforms, and cameras).

• Experience profiling and optimizing rendering performance and memory usage.

• A strong eye for visual quality, lighting, and detail.

Nice to Have

• Gaussian splatting or radiance fields (Spark, Luma, 3D Gaussian Splatting, or NeRF-adjacent work).

• Experience with KTX2 and Basis, Draco, or meshopt compression.

• PBR materials, baked lighting and lightmap workflows, and HDR or image-based lighting.

• WebXR, VR, or AR (@react-three/xr or similar).

• Familiarity with DCC tools (Blender, 3ds Max, Maya) and capture or photogrammetry pipelines (RealityCapture, Postshot, and similar).

• Experience with Unreal Engine or another real-time engine.

• Experience with React, Next.js, or a monorepo (Nx, Turborepo).

• Architecture, AEC, BIM, or spatial-data background.

• Experience with PlayCanvas

What We Offer

• The opportunity to work on cutting-edge digital twin and immersive visualization technology.

• A collaborative, product-driven engineering culture.

• Competitive compensation and benefits.

• A flexible work environment with real opportunities for growth.
