<p data-start="192" data-end="219"><strong data-start="192" data-end="219">About Black Forest Labs</strong></p> <p data-start="221" data-end="611">We're the team behind Latent Diffusion, Stable Diffusion, and FLUX—foundational technologies that changed how the world creates images and video. We’re creating the generative models that power how people make images and video—tools used by millions of creators, developers, and businesses worldwide. Our FLUX models are among the most advanced in the world, and we're just getting started.</p> <p data-start="613" data-end="845">Headquartered in Freiburg, Germany with a growing presence in San Francisco, we're scaling fast while staying true to what makes us different: research excellence, open science, and building technology that expands human creativity.</p> <p data-start="852" data-end="869"><strong data-start="852" data-end="869">Why This Role</strong></p> <p data-start="871" data-end="959">Our research team moves fast. Models improve weekly. New capabilities emerge constantly.</p> <p data-start="961" data-end="1024">What slows us down is not model quality—it’s productionization.</p> <p data-start="1026" data-end="1044">Without this role:</p> <ul data-start="1045" data-end="1230"> <li data-start="1045" data-end="1106"> <p data-start="1047" data-end="1106">Research checkpoints sit longer before becoming usable APIs</p> </li> <li data-start="1107" data-end="1148"> <p data-start="1109" data-end="1148">Inference is slower than it needs to be</p> </li> <li data-start="1149" data-end="1175"> <p data-start="1151" data-end="1175">APIs struggle under load</p> </li> <li data-start="1176" data-end="1230"> <p data-start="1178" data-end="1230">Demos don’t reflect the true potential of our models</p> </li> </ul> <p data-start="1232" data-end="1419">This role removes the bottleneck between frontier research and production reality.
