Engine & SDK Tech Lead - ByteDance

Polluxa, Inc.; San Jose (CA); On-site; USD 180,000 - 240,000; Full time

Job summary

Polluxa, Inc. in San Jose, CA is seeking a Lead Graphics/Engine Architect to shape the next-generation XR engine, graphics, and SDK features.

You will drive cutting-edge rendering techniques, optimize performance, and collaborate with OS, Engine, Product, and Hardware teams to deliver low-latency, high-visual-quality experiences. You will mentor engineers, design developer-facing APIs, and push innovation in real-time ray tracing, neural graphics, and XR runtime infrastructure.

Responsibilities

• Lead the technical vision and architecture for next-generation game engine, graphics, and SDK features in XR
• Drive cutting-edge graphics research and innovation — advanced rendering techniques, performance optimizations, and novel XR-specific rendering pipelines
• Architect and evolve developer SDKs that enable external creators to build best-in-class XR experiences
• Collaborate with OS, Engine, Product, and Hardware teams to deliver seamless end-to-end XR experiences, with obsessive focus on performance, latency, and visual quality
• Explore and prototype emerging technologies — ray tracing, foveated rendering, neural graphics, eye/face tracking integration, and beyond
• Mentor and grow a team of strong graphics and engine engineers, setting technical direction and raising the bar
• Hands-on experience in game engine development, 3D graphics, or rendering systems, with a proven track record of shipping high-performance graphics features
• Deep expertise in modern rendering pipelines, shader programming (HLSL/GLSL/SPIR-V), and graphics APIs (Vulkan, Direct3D, Metal, or OpenGL ES)
• Advanced proficiency in C/C++ and low-level systems programming, with a strong sense of performance and memory
• Strong foundational knowledge of game engine architecture — rendering, physics, input, animation, and asset pipelines
• Solid understanding of modern mobile or console graphics pipelines and hardware constraints
• Experience designing and building developer-facing SDKs, APIs, or frameworks
• Prior experience in AR/VR/MR development, XR runtime infrastructure, or spatial computing
• Expertise in advanced rendering techniques: 3DGS, neural rendering, real-time ray tracing
• Background in game engine development (Unreal, Unity, or custom engines), especially in graphics or low-latency input pipelines
• Experience with compute shaders, GPU-driven rendering, or heterogeneous computing
• Familiarity with native Android development, including Android Services, IPC, and NDK
• Open-source contributions or published work in graphics, engines, or related fields
