We're seeking someone who can help make major contributions to our new frontend growth strategy by ensuring a high quality user experience while working closely with your backend colleagues.

This will include working on a new JavaScript SDK that will impact all team.blue brands as well as merchants across Europe and their millions of transactions.

What we offer

You will be joining a high-impact team where your ideas matter. At OnPay, we combine the agility of a small team with the resources and opportunities of being a part of team.blue. Our flat structure means ideas go from concept to production, with minimal bureaucracy in the way.

We believe great work happens when talented people are given the space to focus. That's why we minimize meetings and protect deep work time, allowing you to craft exceptional solutions for our customers.

Working with us, you will get:
