Full description

Find the weakness before anyone else does.

A multinational defence organisation is adding a penetration tester to its offensive securitycell. The work is a genuine mix: hands-on testing, red and blue team play during large militaryexercises, and the design reviews that stop a weakness being built in the first 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, boards and senior officers, and writing it up so eachaudience can act on it
  • Working closely with accreditation and configuration control bodies so findings turn into fixes

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

Why this one is worth a look

Real offensive work against serious targets, with exercises that most testers never get near.
