Job description

Cyber Security Consultant (Defence Sector, Security Cleared or Clearance Eligible), London - Hybrid

A leading Big Four professional services firm is hiring cyber professionals in London who hold security clearance or are eligible to obtain it, to support a growing programme of defence related work. If you have worked on sensitive or government projects, or you are keen to move into that world, this could be the move you are looking for.

The roles span cyber defence and cyber strategy work, so there is room for technical, assurance and advisory backgrounds alike. The focus is mainly Manager level, with some Assistant Manager opportunities, and you could be delivering client engagements, leading workstreams and supporting the growth of the team.

What you could be doing

• Working on cyber engagements for defence and other security-sensitive clients
• Delivering technical security testing and assurance, or advising on security strategy, risk and compliance, depending on your background
• Working directly with clients and explaining findings and recommendations clearly
• For more experienced people, leading engagements and mentoring colleagues

What you will bring

• Current security clearance, or eligibility to obtain it (eligibility usually depends on UK residency and background checks, which we are happy to talk through)
• Solid experience in cyber security across technical, assurance, risk or advisory work
• Confidence working with clients and communicating clearly at different levels
• Willingness to work extra time on site where defence projects require it
• Openness to occasional on-call requirements where relevant

What to expect

The working pattern is hybrid, generally two to three days a week in the London office, with some defence work needing more time on site. We will talk through your clearance, availability and the specific role and timings on an initial call, so you know exactly what you are applying for.
