Full description

A multinational defence organisation is adding two penetration testers to itsoffensive security cell. The work is a genuine mix: hands-on testing, red and blue team playduring large military exercises, and the design reviews that stop a weakness being built in thefirst place.

What you would be doing

  • Testing web applications, infrastructure and application layers, with the tooling andmethodology the job deserves rather than a scanner and a template.
  • Leading or joining red and blue team activity during military exercises.
  • Reviewing security designs against policy, and advising projects before decisions harden.
  • Briefing what you found — to engineers, to boards, and to senior officers — and writing it upso each audience can act on it.
  • Working closely with accreditation and configuration control bodies so findings turn intofixes.

What you would bring

  • More than three years of web application and IT infrastructure penetration testing.
  • Network security architecture, and vulnerability assessment across operating systems,software, protocols and networks.
  • System and network administration on both UNIX and Windows.
  • Scripting in at least one of Perl, Python, Ruby or a shell.
  • Authentication and security protocols, cryptography, application security, malware techniquesand the defences against them.
  • Report writing you are proud of: executive summary, technical findings, a remediation plan.
