Prestigious financial institution is looking for an experienced Calypso/Java Developer. You would primarily be working on the Calypso system, but would also be working on a variety of other projects including self-clearing, Live Risk/PnL aggregation, containerisation, and technical debt analysis.

Role description

A little backround about the company;

As a private financial company, we work alongside our users and we support the applications that we write. This means we get instant feedback on our work. Instead of communicating over email and incident tickets, we go and talk to our users to get requirements. In turn, they come to us with support issues. We work on-site with our QA team to automate our testing. We also have our own infrastructure team to manage our server hardware, databases, networks, cybersecurity. We work directly with them to ensure that we deliver stable and performant apps, quickly and safely.

All this means you’ll need good communication skills and the ability to deal with everyone across the software stack. Other companies refer to this as ‘DevOps’. We just call it being a good developer.

The reason we work like this is that we have an ever-changing set of deliveries. We work on delivery timescales from 1 hour to a max of a few months. We don’t deal in long, verbose specs that are out of date by the time they’re finished. We have Continuous Integration and deployment across the stack so that developers can focus on the code and not waste time figuring out how to deploy it.
