He ensures building and implementing an enterprise application, contributes to low-level design, writes code to ensure optimum efficiency and functionality and user experience. Main tasks are: - develop, engineer and integrate components - analyse and implement technical and business requirements - resolve issues prior to and following testing - aware of and address known security vulnerabilities, applying security by design - support the specification of the software architecture - follow user experience guidelines - shape documentation - provide advanced, component technical support The professional will be part of an international and mixed team of civilians and military that maintains and develops an enterprise application to reflect and support the core business of the European Air Transport Command (EATC). The software is called "Management of European Air Transport" (MEAT) and runs as a web-based IT-service for in-house and external users from within a classified and secured network environment. The individual to be hired will support the development efforts to modernize and properly prepare the aforementioned application to qualify for higher security levels (Dutch national security accreditation). Most significant enhancements to be implemented/ considered in this context are a) an improved role-based access control and b) a data sanitization control mechanisms, which meet privacy and security requirements. In addition, certain outdated technologies are to be renewed, while large parts of the existing code can be reused. Implemented functionalities have to be documumented to support the software architecture documentation based on the arc42 template.
