Why This Organisation

Our client is a world leading provider of financial markets infrastructure, operating at the heart of global financial and commodities markets from more than 60 offices across 27 countries.

Self organising, cross functional Agile teams, a genuine focus on cloud native architecture and automation, and a culture built around continuous improvement and knowledge sharing.

This is a company that is genuinely investing in Belfast. They have hired 12 engineers here already this year and to support that growth they have moved into a brand new office in Belfast city centre, purpose built to house the expanding team and give engineers the environment they need to do their best work.

It is a core part of a global engineering organisation tackling complex, large scale problems with modern technology and real autonomy.
