Senior Backend Developer Distributed Ledger Technology (d/f/m)*

Start date: 01.05.2021 | Job: Permanent, full-time | Place: Frankfurt am Main or Remote

We are Cashlink

We are Cashlink – a financial technology company offering one of the leading software solutions for asset tokenization. Our clients benefit from all building blocks, services and licenses needed to issue tokenized securities and manage decentralized security registries.

The presence of a high number of intermediaries like banks and custodians leads to high transaction costs on the capital market. We use Distributed Ledger Technology to provide a global capital market 2.0 that works for everyone without intermediaries. We’re on this mission to create a more open access to capital and therefore more thriving ideas coming to life.

Help us to extend the core Distributed Ledger Technology components of our software-as-a-service product that makes the transfer of assets and capital as easy as sending a text message.

We’re excited to get to know you!
