What the job involves
- We're looking for a Senior-level Fullstack Engineer with a strong backend skill set to build internal tools for Developers. As your first priority, you'll extend our V1 Remote Development Environment
- We’ve got 50+ Engineers working remotely primarily across Europe and you’ll build internal tools to aid their productivity. Your first project will be on extending the V1 of our Remote Development Environment
- Extend the V1 of our Remote Development Environment
- Work truly fullstack, from server side development to frontend and infrastructure
- Build and develop effective relationships with other Engineers to drive adoption of the tools you build

- We have a fast yet non-hacky development style. We work strictly with product managers who have a technical background. As a result, we do not overwhelm engineers with unrealistic expectations

- Our engineers have one sync meeting per week + a Manager 1:1, async text Slack dailies, we have no dedicated QAs, we work in super small & independent teams, we have no Jira and in our team, we only have engineers, no code monkeys
Our take
Video is an integral part of companies’ marketing strategies, and the adoption of synthetic media has grown in popularity. As organisations are investing in videos, startups are building platforms to support the process. Synthesia is an AI-powered video generation platform that saves enterprises up to 100x the cost and time of producing a video.
The company leverages deep learning to simulate real videos and real actors without the need for costly infrastructure like camera crews, actors, cameras, studios, and a lengthy post-production process. Synthesia’s first product STUDIO launched in public beta in the summer of 2020 and it is now used by 30,000+ companies, including the BBC, Teleperformance, Amazon, and Reuters.
Notably, Prof. Matthias Niessner, one of the co-founders of the company, is behind some of the most well-recognised research projects in the field Deep Video Portraits and Face2Face. The company's intuitive interface has grown to become the #1 rated video creation platform, proving its strong ability to capitalise on the growing AI in media market – which is estimated to be worth $99.48 Billion by 2030.
