# Senior Penetration Tester and Security Design Reviewer for NATO with security clearance

**Company:** WLG
**Department:** Security
**Location:** Mons

This role sits in a penetration testing cell and covers both halves of the discipline: the testing itself, and the part that decides whether anything gets fixed — reviews, advice and briefings to people who will act on them.

A distinctive element is the exercise work. You would lead or join the red or blue team during military exercises, which is testing under a clock and in front of an audience.

**What you would be doing**

- Lead or take part in the red or blue team during military exercises.
- Deliver web, infrastructure and application-level penetration testing.
- Run security design reviews for compliance with the governing policies and directives.
- Advise projects and programmes on security, and say plainly what has to change.
- Build and sustain communication with the accreditation boards and the units supporting them.
- Brief at executive and technical level on findings and testing outcomes, up to flag-officer level.
- Coordinate proactively with internal and external stakeholders alongside the head of the cell.

**What you would bring**

- More than three years across web application and IT infrastructure penetration testing.
- Network security architecture design, and assessment of vulnerabilities in operating systems, software, protocols and networks.
- System and network administration of both Unix and Windows.
- Penetration testing tools, techniques and recognised methodologies.
- Scripting in at least one of Perl, Python, Ruby or a shell.
- Technical depth in system and network security, authentication protocols, cryptography, application security and malware.
- The ability to evaluate risk and write the mitigation plan, not only the finding.
- Clear, structured technical reports with an executive summary, findings and a remediation plan — for several different audiences.

The work is full time on site in Mons, with about ten days of travel within Belgium foreseen.
