Description du poste

Do you want to join the exciting and innovating world of online banking?

Keytrade Bank is a young bank, where IT systems traditionally were all developed in house. Currently we are moving to a model where we focus on customer experience and innovative products, relying more and more on off-the-shelf products and services for the basic functionality. Where in the past, responsibilities were organized by technical competences, we now are organizing them per business domain, called Feature Team.

The creation of new products requires strong interaction between all IT fields: the back-end; the front-end, database, infrastructure, vendors and service providers.

Working in a small bank is very different than working in a big bank. Responsibilities are greater, knowledge broader. We have a very high growth rate and we are looking for motivated people willing to become part of our dynamic teams to help improve and transform its existing trading and banking system.
