Job Description

About us


Fidesmo is a technology startup based in Stockholm with a research and development center in Madrid. We are building a platform to distribute contactless services to any device having a secure chip: in other words, we want that any watch, bracelet, ring, piece of clothing or even subcutaneous implant (yes, you read right) can be used to pay for a purchase, hop on the train, get inside an office building or rent a car.

This requires writing code that runs on a chip with only a few kilobytes of RAM, or very scalable server code, or code that controls security devices according to the strictest standards from the payments industry. Plus the clients (Android, iOS, JavaScript and also command line). We can say that in Fidesmo we do a bit of everything, and, though this position focuses on developing our backend services you will also have the opportunity of working in other areas. By building our own product we are free from the typical pressure coming from contract development: we program with quality following our own rules.

You can find a technical description of our platform in the Developer Portal. The Fidesmo Android app is published in Google Play. Fidesmo has also open-sourced a few components: the Nordpol library to improve NFC handling in Android and FDSM, a command line client.
