Job summary

Unity in San Francisco is seeking engineers to help expand PolySpatial streaming and cross-engine rendering integration. You’ll map Unity graphics to third‑party renderers, preserve fidelity, and build robust pipelines across in‑process, cross‑process, and networked execution.

The role blends shader translation, resource lifetime management, and high‑performance systems work, with opportunities to shape AI-assisted workflows and massive user‑generated content libraries.

Qualifications

• 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 (DirectX, 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.
• Shader cross-compilers, AST manipulators, or shader graph backends are a plus.
• Experience with networked graphics APIs, pixel streaming, cloud rendering, or virtualized GPUs is beneficial.
• Experience building deterministic record/replay systems for rendering, simulation, networking, testing, or debugging is a plus.
• Familiarity with AI-assisted content pipelines, synthetic data generation, ML-based asset optimization, or automated scene analysis is advantageous.

Responsibilities

• Map Unity graphics and rendering features onto third-party renderers while preserving visual consistency and performance.
• Develop compact scene-state representations and compression strategies for meshes, materials, textures, animations, transforms, deltas, and dependency graphs across local and networked execution
• 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 framerates and fidelity while minimizing overhead and sync stalls

Job description

The opportunity

The team behind Unity’s visionOS support, Play-to-Device, and Record & Playback is growing as we prepare for something even more ambitious: adapting PolySpatial to stream Unity content into other game engines and 3D environments — in-process, cross-process, and over the network.

The opportunity

The team behind Unity’s visionOS support, Play-to-Device, and Record & Playback is growing as we prepare for something even more ambitious: adapting PolySpatial 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 graphics, core game engine tech, high-performance networking, distributed systems, and emerging AI/ML-assisted workflows. This is your opportunity to build the fundamental infrastructure for the next generation of interconnected games and intelligent 3D ecosystems.

You'll bridge Unity content into other renderers, 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.
• Develop compact scene-state representations and compression strategies for meshes, materials, textures, animations, transforms, deltas, and dependency graphs across local and networked execution
• 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 framerates 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 (DirectX, 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 building deterministic record/replay systems for rendering, simulation, networking, testing, or debugging.
• Familiarity with MCPs, agentic tool frameworks, AI-assisted content pipelines, synthetic data generation, ML-based asset optimization, or automated scene analysis.
