Back-end Developer - Based in Warsaw

MANGOPAY’s vision is to fuel the success of the platform economy.

We empower the platform economy with our platform-specific payment infrastructure. Since 2013, we have supported 2,500+ clients in e-commerce, retail, and cutting-edge platforms.

MANGOPAY has developed a payment solution that aims to fuel the success of the platform economy. Built around our programmable e-wallet solution, MANGOPAY’s payment infrastructure offers a simple and easily integrated solution that covers platform payment needs with total integration, as well as flexibility and workflows for many business models.

Our teams are split across Europe in eight different locations, with main offices in Paris and Luxembourg. Platforms and marketplaces are thriving and we are looking for outstanding profiles to tackle some of the most ambitious challenges in our field and contribute to our robust growth.

As a Developer you will reinforce one of our teams, organized around functional areas. 

Your main missions will be to :

• Participate in the missions of the development team (developments, code reviews, monitoring of releases, level 3 support...)
• Work in collaboration with the QA and product teams (new features, quality approach,...)
• Propose and implement technical and/or organizational improvements
• Participate in the tech life of the company (watch, meetups, mutual aid, presentations,...)
• You will find an environment with high quality deliverables and high availability requirements coupled with high volumes of data (we process several tens of millions of financial transactions per year), conducive to increasing your skills with an experienced team whose values are mutual support, humility, initiative and continuous improvement
