At SumUp, we are driven to empower small businesses across the globe by de-hassling their lives and helping them to succeed. Our vision as a global FinTech company is to build the first-ever global card acceptance brand, and we are well on our way as small businesses in over 31 countries around the world rely on SumUp to get paid. To get there, we are putting together an awesome team that is committed to one another and to our merchants. You could be our missing link! Help us bring card acceptance to the masses!

Our boldness, startup mindset, empathy and love for product foster a creative environment for our employees.

We believe that together we can help small businesses grow. 

We are looking for a Partner Engineer who can master all the technical aspects of integrating SumUp's APIs and SDKs for mPOS and eCom, to support, QA and gather regular technical feedback from partners.

Your work as a Partner Engineer is ever-evolving. One day, you might be on a call with our Business Team and a prospective partner, scoping a SumUp implementation to meet their needs. The next, you'll do some troubleshooting with a partner’s engineering team to enable them to successfully process their first transaction. After that, you might update the technical documentation to address common questions or challenges you notice integrators are having.

At its core, this is a client-facing technical support position, so you should have an in-depth understanding of technical aspects of web, server-side and mobile development.

SumUp's solution can get a new partner transacting in just a few hours, and you will be a key component in improving that process even further.
