Overview

Job Title:
Senior / Principal Cyber Security Consultant

Salary:
Yes. Let's talk. Though if you're coming with 4 years of experience and wanting 6 figures then this probably isn't the place for you.

Bonus:
Absolutely

This isn’t that ad.

This isn’t a paper-pushing compliance gig either. You’ll be advising defence and critical national infrastructure clients - the sort of places where “oops” isn’t an acceptable incident response plan.

You’ll be helping these organisations protect their ICT investments and defend against the kind of threats that don’t usually make the news (and shouldn’t).

And yes, that means you’ll need to have or be eligible for UK Government Security Clearance. If you hold Green Badge / DV clearance, we definitely need to talk.

What you’ll actually be doing
  • Helping public defence and critical national infrastructure organisations not get pwned.
  • Working on projects where security isn’t a bolt-on - it’s mission-critical.
  • Designing and reviewing architectures with TOGAF, SABSA or similar frameworks. (Knowing the JSP
    604/440 ecosystem wouldn’t hurt either.)
  • Writing risk assessments and security assurance documentation people will actually read.
You’ll fit in if you:
  • Have 5+ years of experience working with complex ICT systems
  • Can hold your own in a room full of stakeholders, whether they’re techies, suits, or someone from MOD who’s still using Windows 7.
  • Know what JSP
    440/604 is without having to Google it mid-meeting.
  • Understand enterprise architecture and aren’t allergic to acronyms like TOGAF, SABSA or NIST.
  • Have a solid understanding of the likes of Information Assurance and Risk Advisory
What we’re really looking for
  • You’ve worked in Defence or Critical Infrastructure. And you didn’t just drop in for a 2-week discovery workshop.
  • You understand that cyber risk isn’t just about patching stuff - it’s about understanding mission impact.
  • You’re a grown-up. You can work independently and still be part of a team. You get the job done, even when it’s messy.
What’s in it for you
  • Interesting work that actually matters.
  • Training that actually leads to certifications, not just a dusty Udemy login.
  • Routes into Principal / Chartered status with the UK Cyber Security Council, and support for accreditations like CISSP, CISM, SABSA, TOGAF, CREST and so on.
The bottom line

If your idea of a “cyber security role” involves shouting “have you tried turning it off and on again?” then this isn’t for you.

But if you’re serious about securing the systems that keep the UK running - from defence comms to critical national infrastructure - then let’s talk.
