Senior Software Engineer

OSI Engineering is a globally leading consumer device company headquartered in Cupertino, CA, and they are seeking a Senior Keynote Shader & Effects Engineer. The role involves owning the design, implementation, and optimization of shaders and visual effects for their custom animation rendering engine.

Responsibilities:

• Designing, prototyping, and shipping new shader-driven visual effects for the Keynote animation engine
• Collaborating with designers to translate creative direction into performant realtime effects
• Writing and maintaining production-quality Metal shaders, optimized for silicon GPUs using state-of-the-art graphics techniques
• Keeping up with the latest best practices in shader and realtime rendering research
• Applying modern testing methodologies to a wide variety of effects across devices

Requirements:

• Proven ability to write highly performant realtime graphics shader code using modern techniques, holding 60/120fps at 4K across a range of silicon, including thermally-constrained devices
• Strong grasp of the realtime rendering pipeline: rasterization, compute, render passes, resource binding, and GPU/CPU synchronization
• Ability to visualize and translate high-level visual concepts into efficient shader implementations
• Track record of owning a subsystem or feature area end to end
• Excellent communication skills
• Degree in Computer Science or equivalent experience/skills
• Deep, hands-on Metal experience strongly preferred. Exceptional GLSL/Vulkan candidates considered if paired with demonstrated low-level GPU optimization work
• Fluency with foundational graphics frameworks and how they interoperate with custom Metal code
• Experience applying ML models and Vision to realtime graphics and image processing
• Familiarity with the broader graphics stack (Core Graphics, Core Animation)
• Familiarity with computer graphics research (SIGGRAPH, GDC, etc.)
• Experience with Motion, After Effects, or other animation/effects tools
• Experience with scripting, unit testing, and automated testing
• Artistic or design background
