Senior Frontend Engineer - Design System

Synthesia is the world's first AI video generation platform. It's a video production studio in a browser; no cameras, no film crews. You simply choose an avatar, enter your script, and your video is ready in minutes. We believe the future of media is synthetic, and we are on a mission to turn cameras into code and make everyone a creator.

In engineering, we are working on a variety of ambitious projects that are critical to our mission. These range from hyper-personalized onboarding, which aims to introduce new customers to Synthesia through a low-latency, highly personalised experience, to creating our own video delivery platform.

This platform, in addition to addressing typical concerns such as video transcoding and tiered storage, will allow us to offer proprietary media formats to our customers, including nonlinear and translatable video. This is a full-time, permanent role. You can work remotely in Europe or hybrid from one of our hubs in London, Copenhagen, Munich, Zurich or Amsterdam. Our base salary range starts at €100,000 (or a local equivalent) and your package would include stock options.
