We are Funding Circle

Funding Circle is the world’s leading marketplace for business loans. Our mission is to create a better financial world.

We're aiming to disrupt the traditional banking system by giving smaller businesses easier access to capital and providing investors with a new asset class. We’re one of the fastest growing companies in the world with offices in Amsterdam, Berlin, London, Madrid and San Francisco.

If you're really bright, innovative and passionate about building a better financial world and want to do something amazing, join us!


Funding Circle in Berlin uses Ruby on Rails and Symfony2 & PHP for the core platform, and we are revamping the architecture to include Apache Kafka/Samza, Elasticsearch, Clojure and Go. The system includes Salesforce and Big Data technologies like Hadoop / Hive.

We are a test driven team where English is the common language, but you'll hear Russian, Spanish, French, Arabic, Romanian and Dutch in our Berlin office every day as well.

This is a hands-on position, where you will design, test and implement core features of the platform in close cooperation with stakeholders, product management, and users of the system.

We are part of the global Funding Circle team, so you'll have colleagues in London and San Francisco, that are living at the cutting (and sometimes bleeding) edge with Clojure, Mesos, Docker and more.
