About Bubo²
Bubo² is building high-fidelity, photorealistic 3D experiences for the web. We turn photos and videos into web-ready 3D Gaussian Splatting (3DGS) models, enabling interactive visualization of real-world assets such as equipment, vehicles, marine assets, real estate, and e-commerce products.
We are an early-stage startup with a small, highly technical team. As an early employee, you’ll have significant influence over architecture, development process, and product direction, working directly on problems at the intersection of real-time graphics, web platforms, and large-scale 3D data.
Role overview
As a graphics engineer at Bubo², you’ll design and build the core real-time rendering systems that power our web-based 3D products. You’ll work deeply across the graphics stack, from data formats and GPU memory layout to high-level viewer features.
Your responsibilities will include:
* Designing and implementing Three.js-based rendering pipelines for 3D Gaussian Splatting (3DGS) and point-based data
* Building high-performance rendering paths using WebGL2, and experimenting with WebGPU implementations for future use
* Developing custom compression formats and streaming pipelines for large-scale 3D scenes
* Implementing LOD systems, occlusion culling, and GPU-side optimizations to enable smooth rendering on consumer hardware (including phones and tablets)
* Optimizing CPU/GPU synchronization, memory usage, and frame times across a wide range of devices
* Building interactive viewers for e-commerce product showcases and real-estate virtual tours
* Prototyping, experimenting, and making architectural decisions with a high degree of autonomy
What We’re Looking For
Required
* Strong experience with Three.js, including a solid understanding of its internals
* Deep understanding of WebGL2 and GLSL
* Proven experience building custom rendering pipelines or non-trivial 3D systems
* Strong grasp of real-time graphics fundamentals (buffers, shaders, batching, culling, LOD)
* Ability to reason about performance, memory layout, and GPU constraints
* Comfortable working in a small, fast-moving startup environment with high ownership
Nice to Have
* Experience with WebGPU
* Prior work on point cloud rendering, Gaussian splats, or non-mesh-based rendering
* Experience with streaming large datasets over the network
* Familiarity with GPU-side sorting, point cloud LODs, etc
What We Offer
* Competitive salary based on experience
* Stock options — ownership in what you’re building
* High degree of ownership and technical freedom
* Opportunity to work on cutting-edge rendering problems on the web
* A small, senior, and highly technical team with direct access to the founders
If you’re excited by real-time graphics, the web as a platform, and building foundational 3D infrastructure from the ground up, we’d love to talk.
