Do you want to move fast and break nothing for 1 billion banking customers? We’re a global tech company that’s taking banking software to the next level, (and we’re definitely not a bank).

We’re looking for highly skilled Java engineers who are passionate about security, reliability and scalability in large distributed systems.

We are building a core banking platform – all the stuff a typical retail bank does: bank accounts, saving accounts, mortgages, bank cards, loans, etc. This platform must work - every time, all the time. We never want to have a customer suffer a ‘card declined’ because of an outage or defect – it’s an anathema to us. For added challenge, we aim to scale this to 1 billion banking customers across both large and small banks globally.

So, we care deeply about blending cutting edge technology with battle hardened tech and proven principles regarding architecture, security, and delivery.

No banking or financial services experience is necessary – we already have an amazing team that knows this domain to perfection – we’re looking for excellent engineers, regardless of domain background – diversity of thought enables better solutions.
