What we offer

Working at a fast-moving startup like SatoshiPay means that all your contributions will have a direct impact on the product and by extension on how people will use the internet in the future. The SatoshiPay team is well-connected, both in the FinTech and the blockchain scene, so you'll also benefit from being exposed to these communities. We are an open-minded team that works closely together in a non-hierarchical manner at our office in the heart of Berlin.

We are big believers (and users!) of open source software, so you will also be working on software that is released under an open license and take part in open standards activities. We are also regularly attending hackathons and tech conferences.

  • Health care and retirement plans
  • Fresh fruits and free drinks
  • Ergonomic desks and chairs
