Senior / Staff ML Engineer

Recraft is a graphic design research lab building state-of-the-art image generation models and tools for designers, illustrators, marketers, and developers.

Founded in 2022 and based in London, we build for commercial design standards: full creative control, style consistency, and native vector outputs, an API for teams who want to integrate that capability directly into their workflows, plus mobile app for those who prefer not to be distracted from the process without a computer.

Over 3 million creators across 190+ countries use Recraft. Our mission is to help everyone who works with visuals get the job done, without lowering the bar on design.

If you want to help set that standard, we'd like to hear from you.
