Hey there, hope you're having a fab day 👋

Few important things first: we pay very well (salary + stock options) + we try to be super quick and responsive in the hiring process.

Synthesia is the global leader in synthetic media. Our vision is to build the first fully programmable video generation platform and help everyone transform non-video content into video.

Synthesia is already working with some of the world’s biggest companies and celebrities such as David Beckham and Lionel Messi, BBC, EY, Facebook, McDonalds, Amazon and WPP.

Our Messi campaign collaboration also received a Cannes Lion Award in 2021 and we’ve raised more than $16M so far from names like Mark Cuban, First Mark Capital, Seedcamp and more.

You'll have a chance to work on scaling our current, fast-growing product and shape some of the next products in our pipeline. This will be a dream job for you if you enjoy deep, uninterrupted work. Some of the projects our backend engineers work on include building out a custom video/audio rendering pipeline, implementing real time collaboration, optimizing video delivery/streaming, solving scaling problems, etc. Our tech stack is: Python, C++, React, node.js, PostgreSQL, MongoDB, AWS.

💡Important to know: 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/requirements, and we can therefore move forward much faster. Read more about how we work in this Linkedin post.
