Principal Level Rendering Engineer (Light Fields)

Location: Paris, France; hybrid

Company

hirify.global is building Nyx, a hybrid renderer for robotics that combines next-generation light field capture and Gaussian splatting with realtime performance and offline-quality output.

What you will do

• Design and implement light field generation and reconstruction pipelines.
• Build and optimize Gaussian splat generation, training, compression, and realtime rendering.
• Own color science across camera characterization, color spaces, tone mapping, HDR output, and display calibration.
• Turn research papers into robust, performant production code.
• Collaborate with capture, ML, and platform teams on pipeline architecture.

Requirements

• PhD in computer graphics, computational imaging, computer vision, or a related field, or an equivalent research track record.
• Publications at venues such as SIGGRAPH, SIGGRAPH Asia, CVPR, ICCV, or EGSR.
• Hands-on experience with radiance fields, 3D Gaussian splatting, or light field rendering beyond toy implementations.
• Strong grounding in color science, including colorimetry, camera ISP pipelines, and ACES or similar managed workflows.
• Strong C++ and GPU programming skills, including CUDA or compute shaders, plus Python for research tooling.

Nice to have

• Industry experience shipping capture, VFX, or realtime rendering products.
• Experience with differentiable rendering, novel view synthesis, or neural compression.
• Familiarity with HDR standards such as PQ and HLG and with display characterization.
