We are now looking for a talented API Integration Engineer to join our dynamic technical team in Vienna (Austria), Warsaw (Poland), Brussel (Belgium), Seclin (France), or Villeurbanne (France), helping us support and improve our cutting-edge integrations, with a focus on next-generation API integrations — essential components of financial services (for example, Tap on Mobile (ToM) and Terminal API).
Join us as an API Integration Engineer and become a key player in ensuring seamless communication between internal systems and external clients. You will act as a vital link between our engineering teams and our customers/partners, troubleshooting and resolving integration issues while continually seeking ways to optimize system performance.

If you are passionate about tackling technical challenges in a global environment and want to make a tangible impact in the financial technology industry, this is the role for you.
We are seeking a proactive problem-solver with a strong technical background and excellent English communication skills. The ideal candidate is open-minded, flexible, a genuine team player, and capable of working independently in an international context.

A Master’s degree or equivalent is required, with 4–5 years of experience in a similar role, ideally supporting API integrations (including the ECR API). Excellent command of English, both spoken and written, and a good understanding of hardware/software environments are essential. The role requires an open-minded attitude and the ability to work effectively with a distributed, global team; potential locations include Vienna, Warsaw, Paris, Seclin, and Villeurbanne.
