Job Description

Your mission

At Papercup we’re on a mission to make the world’s videos watchable in any language. We’ve invented a patented AI system that generates humanlike synthetic voices across languages, allowing people to watch video content in the language of their choice. Our translated and dubbed content has allowed the likes of Insider, Discovery, Sky News, and Canva to reach over 300 million people globally in just the last year.Having just completed a $20 million Series A round, we're on the hunt for top people to join our ambitious mission.

We’re backed by some of the industry’s heaviest hitters - venture funds like Octopus Ventures, world-renowned angel investors including Des Traynor (co-founder of Intercom) and John Collison (co-founder of Stripe), as well as global media groups like Sky and Guardian Media Group.

We are driven, curious and passionate - our company culture is imperative to us and we set a high bar for those who join theteam. We're also fun to be around (at least that's what people tell us).

The FlexScore® is the result of a rigorous 2-step verification of a company’s flexibility

First we assess the flexibility options Papercup provides and then we anonymously survey a statistically significant proportion of their employees to make sure Papercup is as flexible as they say they are. Our assessment is based on the six key elements of flexibility: location, hours, autonomy, benefits, role modelling and work-life balance.

We ask the hard questions so you don’t have to.
