CoreTech Security’s mission is to deliver high-end security research and bespoke solutions to some of the most interesting cyber security clients in the UK. In practice, this means that we have built a world-class team of vulnerability researchers, reverse engineers, and high-assurance software engineers.

CoreTech is looking for talented students with an active interest in subjects such as ethical hacking, vulnerability research and reverse engineering, to join our world-class research team for a paid summer 2027 internship. If you are going into your final year in 2027 you may be offered a contract for our 2028 graduate intake on completion of your internship.

By working closely with your peers in small, usually two-to-three person teams, our interns rapidly develop the skills necessary to deliver bespoke research and capabilities for our most trusted clients. Our intern projects are chosen specifically to give you direct insight into the sorts of projects we deliver for our clients, with real demands and as-yet unsolved technical challenges you’ll be expected to best. Just ask our previous interns!

Reasons to use Rodeo

I’m in my final year doing Economics and I don’t know whether to apply for grad schemes now or do a masters first. What do you think?

Honest answer — it depends on where you want to end up. A lot of top grad schemes (Big 4, civil service, banking) don’t need a masters. Let’s look at the ones you’d be competitive for now, and we can decide if a masters actually adds anything.

Also worth knowing: most autumn 2026 applications are open now. Timing matters more than you think.

Start with a chat, not a search bar

Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
