Description

Cryptography Evaluator Engineer in the System Security Section (TEC-SES), End-to-End Systems Division, Systems Department, Directorate of Technology, Engineering and Quality.

The System Security Section is responsible for the end-to-end system security engineering of the Agency’s missions, projects and activities in space, ground and user segments and communication links, as well as at system, subsystem, element and equipment level. It covers missions from study phase to definition of requirements, design, development, security integration / verification, and security service preparation, across the full stack, from physical to application layer.

To serve these functions, the System Security Section defines and executes the associated technology R&D and studies, as well as the required security engineering standards.

Using security laboratory facilities, the System Security Section performs vulnerability assessments at all levels of its responsibility, proposing detection methods, mitigation and protection measures, using security assessment tools and equipment.

This position will support a third party activity for the development of a national capability on the evaluation and certification of cryptographic algorithms and protocols.

Duties

Your tasks and responsibilities will include:

supporting the project manager by providing recommendations and guidance on the evaluation and certification of cryptographic algorithms;
regular reporting to the Project Manager on the status of the duties assigned under the Project;
direct engagement with and advice to national customers and ESA experts on the strengths, weaknesses and design of cryptographic algorithms and parameter selection for them;
deriving recommendations on cryptographic algorithms in relation to use case and security strength;
fostering new security application areas for multidisciplinary activities, placing emphasis on innovative concepts, cutting-edge technologies and system architectures in the field of crypto algorithm evaluation and certification;
supporting the training of colleagues, as required;
continuously following technological trends and evolutions in the scientific fields relevant for this position, and in particular on the latest emerging threats, exploits, and industry trends;
being engaged in other technical activities outside the main project in the area of your expertise, as requested.
