What will be your role?

At TNO, we have in-depth knowledge of (technical) cyber security and quantitative models and algorithms, as well as wide experience in developing and applying innovative technology and methodologies. Armed with that knowledge and experience, you and your team will ensure that organisations can rely on secure and robust ICT networks and services both now and in the future. You’ll work closely with partners including universities, other knowledge institutes, service providers and product suppliers, both in the Netherlands and elsewhere. Your department’s work ranges from independent advice to exploratory research on high-potential technology. We also make technology applicable for a specific client or context, for example by developing a proof-of-concept. Our clients include the Dutch Ministry of Defence, financial institutions, telecom service providers, and parties in the mobility and logistics sectors. For many of those clients, secure and robust ICT is a crucial business success factor.
Here are some examples of interesting projects of the CSR (Cyber Security and Robustness) department and TNO: 
  • Developing technology for detecting advanced cyber-attacks, together with various national and international partners;
  • Investigating the security of new and planned systems for banking transactions;
  • Researching the applicability of advanced cryptographic technology in the medical field, together with university and industry partners;
  • Analysing and benchmarking the security level of European telecom providers, commissioned by the international sector association;
  • Research programmes for the Dutch Ministry of Defence aimed at expanding its cyber security capability.

In order to expand our team, we are looking for a Junior Cyber Security Researcher.
As an aspiring Cyber Security researcher, you’re fascinated by technology and you enjoy discovering more about new technologies and related issues. You’ll soon join project teams working on innovations in the field of Cyber Security. The projects will often be carried out in collaboration with partners from outside TNO. With your sound IT background, you’ll deal with the actual technology in your projects. The work of a Junior Cyber Security Researcher at TNO offers a great deal of variety. You’ll be working on a number of different projects simultaneously, together with colleagues from your own department, but also with colleagues from other (IT) disciplines. Depending on your personal interests and abilities, these projects will range from short-term consultancy for clients to long term research, or a combination of these. An important part of your work will involve creating proof-of-concepts and developing new technology. Since in this position you will be working together a lot and will be working for and/or with clients, good social skills are a must.
As you go along, you will choose your focus and/or role (e.g., applied research, consultancy) and develop into an expert in one of the areas in which TNO is active.
