A day in the life of...

Covert Technical Operations Specialist

Ever since secondary school, I've enjoyed tackling new technology projects in my spare time. So studying computer science at university was a no-brainer for me.

And my passion for digging deeper into technology and exploring the edge of what's possible were two of the reasons I wanted to join MI5.

I haven't been disappointed. Life as a Covert Technical Operations Specialist is fast-moving and exciting; the technology in incredibly advanced.

And it has to be. Historically, the agency intercepted physical documents. Now we're conducting operations to access the computers and devices used by terrorists planning attacks, and always within our legal remit.

I have to explore and explain the risks. The technology terrorists are using is constantly changing. From SMS just five years ago they are now using a range of platforms to communicate and share information. Some use sophisticated encryption, so we have to think differently.

It means there's a lot of variety - you genuinely don't know what you're going to be working on each day.

It can get quite intense and sometimes I need to work odd hours, but I love my job and I get great training, as well as a good work/life balance.

And I know that what I'm doing has a real impact on keeping the country safe from terrorists, spies and other groups who want to harm the nation.

Why join MI5?
