Senior Real-Time 3D Engineer — Performance & SDK Lead

Moon; Glendale (CA); On-site; USD 120,000 - 160,000; Full time

Job summary

Moon is seeking a frontend/graphics engineer to advance real-time 3D in React Three Fiber and Three.js, delivering a home-focused 3D experience for homeowners and designers. You will optimize for frame rates, memory budgets, and fast render times on tablets in the field.

You will build clean abstractions, ship daily behind feature flags, and collaborate with a senior team to push data formats, scene graphs, materials, and lighting toward high-performance, production-ready pipelines.

Qualifications

• 5+ years in frontend/graphics with production Three.js or React Three Fiber.
• Strong 3D fundamentals: scene graphs, materials, lighting, geometry, GPU performance.
• Experience optimizing data formats, asset pipelines, or file sizes with measurable results.
• Profiling depth across GPU, CPU, and memory to identify bottlenecks.
• Experience building libraries or SDKs consumed by other teams (a plus).
• Pragmatic, detail-oriented, and fast-moving.

Responsibilities

• Develop new 3D capabilities exposed as clean, versioned APIs.
• Own render and runtime performance on real devices: frame rates, load times, memory budgets.
• Optimize core 3D data formats and loading strategies (sizes and pipelines).
• Deep scene-graph work: materials, geometry, lighting, instancing, data-driven assembly.
• Write documentation and examples to enable teams; support consuming teams on rotation.
• Ship daily behind feature flags with AI-assisted workflows on a shared design system.
