Product Engineer

About Black Forest Labs

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.

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.

Why This Role

We're looking for a Product Engineer to build the experiences people meet our models through.

You'll work alongside our researchers and infrastructure engineers to turn frontier model capabilities into interfaces that feel fast, considered, and obvious to use.

You'll own the surfaces developers and creatives touch first:

Playground - where most developers and creatives experience and test our models

Dashboard - where developers manage keys, usage, and billing

Launch demos for new FLUX models, often built against checkpoints nobody outside the lab has seen

Reference implementations and starter apps that other developers build on top of

Day to day, that means:
