C Developer


Within our Amsterdam based dev team we have a team of highly skilled C developers working primarily on our Point-Of-Sale (POS) PIN Terminal solution. Most POS terminal vendors, for instance Verifone, require our custom PIN terminal software to be written in C. Within the team there is a lot of freedom and ambition to develop cool and unique features on the device. Next to this the team has built robots (video) to test the PIN devices, to allow for automated testing. As we have so many innovative ideas we are looking for more talent to further improve the most advanced and robust platform in the payment industry.
