Security Testing Role – Dive Deep, Make an Impact
You love uncovering what’s beneath the surface. Whether it’s a telecoms protocol or a complex IT system, you’re motivated to understand how things work — and how they can be made more secure. You bring a hands‑on mindset to testing and analysis, and you’re motivated by the real‑world impact your work can have.
In this role, you’ll be part of a collaborative, inclusive team that values fresh ideas, different perspectives, and mutual support. You’ll have the freedom to explore, experiment, and grow — all while helping to build more resilient networks.
What You’ll Be Doing
- Testing hardware and software components to uncover vulnerabilities in complex systems.
- Use positive and negative testing techniques (including fuzzing) to push network functions and protocols to their limits.
- Script and automate your assessments to boost efficiency and repeatability.
- Investigate and communicate your findings clearly, showcasing the technical risks and their implications.
- Contribute to high‑quality technical reports that are thorough, insightful, and actionable.
