Job description

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.

• In the coming years, one of the team’s major initiatives will be to make the client onboarding experience smoother, more efficient and more user-friendly, both on mobile and web. This is a key project for the team, with a strong impact on the digital journey of future Keytrade clients.
• You will work closely with frontend and backend developers, business analysts, DevOps engineers, testers, a product owner and a scrum master. As part of the feature team, you will plan, estimate, execute and deliver features on a two-week sprint basis, participating in all agile ceremonies. Keytrade offers a flexible remote policy, allowing you to work from home up to half of the time.
