Job Description

Your mission

We’re on a mission to make the world's videos watchable in any languagePapercup uses AI to dub videos into other languages using the most human-sounding synthetic voices you've ever heard. Leaders in entertainment, news, and enterprise, such as Jamie Oliver, Business Insider and Bloomberg, use Papercup daily to leap language barriers and engage more deeply with their international audiences.

Last year alone, over 350 million people watched videos translated by Papercup. But this is just the start - billions of hours of video are stuck in a single language - our technology will fundamentally change that and make videos watchable in any language.

We’re more than just an AI startup - we also care deeply about our people. We want people to feel fulfilled, rewarded and genuinely happy at Papercup. That’s why creating and fostering the right culture matters to us and why we’re committed to building a company that people are proud to work for.

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.
