Location: Anywhere or Berlin Experience: Senior Architect Principal

Let's build the world's best meeting app for groups together.

Why Us

The origins of Video Conferencing can be traced back to the 1870s.

Not a typo! Look it up. It really isn’t a new idea, although it took about another 100 years to start resembling what we see today. We are fascinated by it, visual and facial signalling makes up over 50% of our communication. Seeing is so much more than just talking.

There are only a handful of companies pushing this technology, I’m proud to say Wonder is one of them.

Your Benefits


This role exists because Wonder is at the forefront of building exciting ways for groups to communicate and interact online.

This is definitely not your average eCommerce, FinTech, or Travel company. In Europe alone there are over 9000 fintech startups, all trying to solve the same problems. Why follow the herd?

In our domain, there are only a handful of companies at this frontier of browser-based applications for online meetings. We see only 3 - 5 serious contenders in this space Globally.

Wonder’s engineering team has unique challenges ahead. Imagine being part of the original V8 team, facing off against Firefox and Internet Explorer in 2006 and trying to 10x JavaScript and ending up 100x’ing it. That’s where we are now at Wonder!
