Vulnerability Researcher Internship

Our client is a cyber security company.

9th November 2026, we reserve the right to close this advert early if we receive a high volume of suitable applications.

Our client'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.

Our client 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!

Our focus is the security of mobile and embedded technologies (although we do occasionally branch out). Our research team use Ghidra as our tool of choice for reverse engineering and produce proof of concepts in the most suitable language for the project which could be C, C++, Python or assembly code. The role requires an inquisitive mindset and enthusiasm for solving challenging research tasks.

An ideal candidate will have:

• A passion for cyber security, a genuine interest in bug hunting and be familiar with recent vulnerabilities.
• A desire to thrive on solving difficult and complex problems.
• Knowledge of vulnerability types (e.g. stack/heap overflow, use after free etc) and common mitigations to prevent such vulnerabilities
• Familiarity with one or more high-level languages such as C, C++ or Java

Skills you may have:

• An interest in how software vulnerabilities and exploits work
• Experience in basic scripting using Python
• Familiarity with the Linux OS and working in the shell
• Participation in Capture the Flag (CTF) challenges
• A basic understanding of how computers communicate (networking)
• Reverse engineering using Ghidra
• Ethical hacking
• Familiarity with Android and adb shell
• Hardware Hacking
• Strong inter-personal skills and enthusiasm for working with others

We are looking for interns with a passion and enthusiasm for cyber security. Ideal candidates will be able to demonstrate an active interest and foundation knowledge in several of the skills listed above.
