Wonderbly is looking for a Product Engineer to join our technology team. In this role you will help us build out our new combined architecture for powering our growing number of personalised book brands.

As an expert, AI-native engineer you are equally comfortable defining and delivering complex capabilities as you are collaborating with commercial owners, designers, product managers and marketeers. You will expand our architecture and tooling that is used across our business to create and expand the capabilities of our personalised book brands and the unique proposition each offers.

This is a full-time position based in our Bloomsbury studio. Because we believe the best collaboration happens in person, our in-office days are Tuesdays and Thursdays, with another day at your discretion. It's a lovely place to do your best work.

What’s important to us

We are a multi-disciplinary business at the intersection of publishing, technology and direct-to-consumer marketing. These domains overlap and we need people who are comfortable contributing and influencing outside their specialist area.

Quality is paramount. We make beautifully made, deeply personal books that people treasure for life. The customer needs to connect with this on first contact with our brands.

We're an AI-first development team. We need people who bring that same orientation: using AI tools thoughtfully to move faster and have greater impact by tackling harder problems.

Most importantly, Wonderbly is a creative, customer-focused company. That means we need people who love ideas, books and creating beautiful things.
