Pentester/Ethical hacker (senior) wanted

Location The Hague – at least 32 hours per week

Are you always looking for unknown vulnerabilities and the most complex exploits? Are you expert at developing exploits yourself and executing pentests ? Do you like to share your knowledge and skills on security, rescue teaming, exploitation and other security topics with colleagues and do you see it as a challenge to include colleagues in your story? Do you like brainstorming about the different services NFIR can offer its customers? In this position you will be technically challenged to get the best out of yourself and the pen testing team and to perform the best pen tests together with your new colleagues.

Pen tests

Pen tests is very important to businesses as companies and organizations increasingly own large amounts of data. With the advent of the GDPR, the security of personal data has become more important than ever and it has become a duty for companies to secure this data. We’re happy to put that security to the test. Together with other ethical hackers/pentesters, you will work with different types of companies and organizations to investigate which vulnerabilities are present in a company.

Nothing is too crazy here: From walk-in actions, performing red-teaming actions, sending (spear) phishing emails, to testing printers and applications and hacking into SCADA systems, NFIR has it all!

As a pen tester, you are also part of our Incident Reponse team.
