At SORAMITSU you'll be developing new financial products and infrastructure that is shaping the way money is created, distributed, and used today. You'll work on enterprise payments & identity software used by centralized authorities around the globe, such as central banks, as well as software that is completely decentralized and governed by the people, aimed at democratizing money & digital assets. Because of this duality in focus, SORAMITSU is a very unique place to work. There are simply not that many companies in the world where you can push proprietary code powering an entire country's payment infrastructure in the first half of your day, and then wrap up your day working on an open source decentralized crypto-asset exchange used by a global audience.
