WE'RE LOOKING FOR SOMEONE WHO...

Thinks like an attacker, but builds like a defender.

You are analytical, curious and naturally investigative.

You don't stop when you've found the immediate problem. You want to know why it happened and how to prevent it happening again.

You can remain calm during high pressure security incidents.

You can take complex cybersecurity concepts and explain them clearly to people who aren't security specialists.

You have the confidence to challenge technical decisions when security risk demands it.

You influence without relying on hierarchy.

And most importantly, you keep learning.

Because the threat landscape doesn't stand still, and neither should your expertise.

WHY TANGENT SOLUTIONS?

Tangent Solutions is a technology business focused on helping organisations build for a dynamic and digital future, with capabilities spanning cloud, software development, intelligent automation, cybersecurity and software defined networking. Tangent Solutions

That means you won't operate in a technology silo.

You'll work in an environment where cybersecurity intersects with cloud, networking, software, automation and digital transformation.

You will have the opportunity to work alongside technology specialists, engage with complex environments and continuously expand your technical perspective.

This is a place for people who want to build, solve, learn and make an impact.

READY FOR YOUR NEXT CYBERSECURITY CHALLENGE?

If you're ready to take your cybersecurity expertise beyond monitoring and into engineering, investigation, architecture, response and transformation, we want to meet you.

Protect what matters. Solve what others can't. Build what comes next.

Your expertise could be the difference between reacting to the next threat and being ready for it.
