Lead Software Engineer

TensorPix is an AI-powered video platform built for real estate agents, photographers, brokerages, and property marketing teams. It turns existing property photos into polished listing videos in 10 minutes. Users can add voiceovers, branding, and music, then export each video in formats optimized for MLS platforms, social media, and websites. Producing a video with TensorPix costs up to 50x less than hiring a photographer or videographer, making professional video marketing practical for every listing—not only premium properties.
