About the Role
You’re someone who can’t help but ask “What’s really going on under here?” Whether it’s a telecoms protocol, a complex system, or a bespoke piece of hardware, you’re driven by curiosity — and motivated by making real world technology safer.
Join a collaborative, inclusive team where your ideas matter, your voice is heard, and your work has genuine impact.
You’ll have the freedom to explore, experiment, and grow, while helping shape the security of next generation networks.
- What You’ll Be Doing
- Conduct all security assessments within our dedicated in-house lab environment, ensuring safe and controlled testing conditions.
- Perform hands‑on penetration testing across hardware, software, and telecoms‑specific technologies to identify vulnerabilities in complex systems.
- Apply both positive and negative testing techniques to rigorously assess network functions, protocols, and system resilience.
Develop scripts and automate testing processes to enhance efficiency, consistency, and repeatability — freeing up time for deeper, high‑impact research.
- Investigate and analyse security findings, clearly articulating technical risks to both technical and non‑technical stakeholders.
Produce high‑quality, actionable technical reports that support remediation and strengthen overall security posture.
