Build treasury systems
with us.

What you'll do

• Design, build and test extensions to treasury and trading platforms (Calypso, Murex or similar): workflows, scheduled tasks, reports, and trade and market-data interfaces.

You have

• A degree in computer science, IT, information systems, software engineering or similar.
• 3+ years of professional software development.
• Strong in at least one of Java, C# or Python. Java is preferred, because most treasury platforms (Calypso included) are built on it.
