Job Specifications

Introduction
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.
Currently we are refactoring our core systems and transforming them in micro services deployed on AWS following Domain Driven Design principles.

You are a team player, always ready to share and discuss ideas in order to improve the existing, and to find solution for new projects. Everyone is acknowledged for their role, and we need people with a strong sense of responsibility in our teams.
You are able to work independently when needed, dealing with tasks from early requirements analysis until final implementation and testing. You are open to interaction with your colleagues, able to reach out for help when required and open to accept or provide constructive criticism. You are eager to learn about trading and banking related matters, and also about new technologies. When it comes to programming, you are meticulous and orderly, without losing your pragmatic attitude.

You will be joining the Trading, Investing & Saving Team (TISA), that is responsible for our trading platform, financial products, and so much more. You will work with several frontend and backend developers, business analysts, DevOps engineer, tester, product owner & a scrum master. As part of the feature team, you will plan, estimate, execute and deliver features on a two weeks sprint basis, participating to all ceremonies, wherever you are, as we have a flexible remote policy that allow you to work from home half of the time.

Academic degree in a technical field or a proven experience of at least 3 years in developing back-end application and integration services
