Working at
Mondido Payments

Mondido is a payment service for e-commerce. Mondido enables clients to increase sales by reducing the amount of failed payments and through optimizing the transaction flow. Mondido offers a simple and fast way to start accepting payments on websites and mobile applications while offering smart features for analyzing and increasing sales. Merchants and web shops can get up and running with payments fast and effective using hosted payment windows, JavaScript forms and API integrations.  Mondido is nothing without our customers. Every feature we develop is based on client needs. We listen very carefully to the market and what we should work on to ensure we deliver excellent value. Further, the customer gets all the power: we never demand them to use our logo in their store or anything like that - our clients should own the experience.  We are driven by innovation, and we want to do things differently and break norms. We are all experts in our fields, and we offer lots of freedom as well as responsibility. We want to be solution-oriented and informal in how we work. At Mondio, we offer flexible working hours and the opportunities to be creative and thrive. The people at Mondido are self-reliant and excellent at getting stuff done.  Sometimes we go out for a nice hotel breakfast to do a little bit of brainstorming, and sometimes we play some ping pong in the office. In between lots of work, we need to have a little fun to stay creative.
