Senior Penetration Tester (UKTL)

You’re driven by curiosity and a desire to understand how things really work – and how they can be made more secure. Whether dissecting telecoms protocols, exploring enterprise systems, or analysing hardware, you take a hands‑on, analytical approach to solving complex challenges. In this role you’ll join a collaborative and inclusive team where your expertise is valued, your ideas are heard, and your work directly contributes to strengthening real‑world systems. You’ll have the freedom to explore, experiment, and grow while helping shape the security of next‑generation networks. As a senior member of the team you’ll also play an important role in supporting and mentoring others, helping to develop the next generation of security testing specialists.

What You’ll Be Doing

• Lead and deliver security assessments across complex hardware, software, and telecoms systems.
• Conduct hands‑on penetration testing within a dedicated in‑house lab environment, ensuring safe and controlled testing.
• Apply advanced testing techniques – including both positive and negative approaches (e.g. fuzzing) – to rigorously assess network functions and protocols.
• Identify, investigate, and clearly articulate vulnerabilities and security risks to both technical and non‑technical audiences.
• Develop scripts and automate testing processes to improve efficiency, consistency, and scalability.
• Produce high‑quality, insightful technical reports that support remediation and strengthen security posture.
• Mentor and support junior team members through hands‑on guidance and knowledge sharing.
• Contribute to the development of test strategies and help shape the direction of security assessments.

Successful applicants must be able to commute to the UKTL offices in Birmingham at least twice a week. We strive to offer a great work‑life balance.
