Senior Software Engineer, Graphics

The opportunity
The team that brought Unity to vision

OS and enabled real-time interaction via Play-to-Device is growing in preparation for something even more ambitious: adapting Poly Spatial to stream Unity content into other game engines and 3D environments—in-process, cross-process, and over the network.

We're looking for engineers eager to help us invent how different real-time 3D runtimes communicate and render under real-world constraints. You’ll work at the intersection of core engine tech, high-performance networking, distributed systems, and graphics. This is your opportunity to build the fundamental infrastructure for the next generation of interconnected game and 3D ecosystems.

You'll bridge Unity content into another renderer, maintaining fidelity and performance within a renderer we don’t own. This requires a rare mix of artistic instincts, low-level API knowledge, and the systems engineering skills to build a robust pipeline. If you prefer solving hard rendering problems at the systems level—shader translation, resource lifetime, visual equivalence—more than chasing one-off visual features, you'll find this work deeply satisfying.

What you'll be doing

• Map Unity graphics and rendering features onto third-party renderers while preserving visual consistency and performance.
• Build shader/material translation pipelines that cross-compile bytecode, convert coordinate systems, and reconcile lighting models across engines.
• Engineer robust graphical systems that remain stable and resource-efficient even when scaled to massive user-generated content libraries
• Profile and optimize end-to-end rendering for high frame rates and fidelity while minimizing overhead and sync stalls

What we're looking for

• Multi-Engine Fluency:
  Significant experience with Unity's rendering architecture, and at least one other high-end renderer (Unreal, Frostbite, etc).
• Shader & API Depth:
  Strong understanding of shader languages (HLSL/GLSL/Metal) and graphics APIs (Direct
  
  X, Vulkan, Metal), and the ability to translate between them.
• Pipeline Mindset:
  You understand the full asset lifecycle—from authoring through import, batching, streaming, and rendering—including shader compilation, mesh processing, and texture streaming.
• Systems-First Engineer:
  You prioritize building stable, scalable, maintainable systems over chasing the latest graphics techniques.

You might also have

• Experience writing shader cross-compilers, AST manipulators, or shader graph backends.
• Background in networked graphics APIs, pixel-based streaming, cloud rendering, or virtualized GPUs.
• Experience with FBX, USD, glTF or similar interchange formats.
• Shipped titles where you owned significant rendering pipeline components
