Rendering Engineer
Department
Engineering
Employment type
Full-time
Location
Belgrade, Serbia
We're looking for a Rendering Engineer to help us build the pixel-perfect, high-performance rendering engine behind Wonder's interactive canvas.
The role
We're looking for a Rendering Engineer who cares deeply about how things look, feel, and perform.
Wonder's rendering system is heavily DOM-based, so this role is for someone who understands HTML, CSS, layout, painting, and browser behavior at a very deep level. We want someone who knows what actually happens under the hood, not just how to use frontend tools, but how rendering works in practice.
You'll work on the systems that make Wonder feel precise, responsive, and polished. That means building for pixel perfection, solving hard performance problems, and making sure the product stays fast even as the canvas becomes more complex.
It's a big plus if you've worked with technologies like WebGL, WebGPU, PixiJS, Three.js, or similar, but what matters most is that you truly understand how these systems work and when to use them.
In one sentence: Build the rendering foundation that makes Wonder feel precise and incredibly fast.
What you'll do
- Build and improve Wonder's core rendering systems for a fast, interactive design canvas
- Work deeply with DOM, CSS, layout, measurement, and browser rendering behavior
- Optimize performance across complex scenes, interactions, and large documents
- Ensure the product feels pixel-perfect, responsive, and visually polished at every level
- Investigate and apply the right low-level techniques when needed, including work across WebGL/WebGPU or custom rendering paths
- Collaborate closely with design and engineering to make sure quality and performance stay equally high
What we're looking for
- Deep understanding of HTML, CSS, DOM, and browser rendering internals
- Strong experience building highly polished, performance-sensitive frontend systems
- A sharp eye for detail and genuine care for visual precision down to the smallest pixels
- Strong intuition for performance bottlenecks, tradeoffs, and rendering architecture
- Bonus: experience with WebGL, WebGPU, PixiJS, Three.js, or other rendering-heavy systems
- Bonus: experience working on editors, creative tools, canvases, or other complex interactive products
