Vulnerability Researcher

About the Role

We are looking for a telecom security researcher to explore unknown vulnerabilities, design tools, and contribute to secure telecom systems.

• Find new vulnerabilities in carrier‑grade telecom systems, conducting research‑led investigations.
• Innovate by building and testing custom fuzzers, software‑radio solutions, or new tools.
• Learn relentlessly by deepening understanding of telecom systems and collaborating with peers.
• Build and experiment in a world‑class lab, designing and evolving infrastructure for research.

• Curious and driven, with a passion for uncovering how systems work and break.
• Understanding of network protocols, low‑level and high‑level programming, assembly, and interpreted languages.
• Knowledge of cryptographic algorithms, encryption, authentication, signatures, and how they can be misused.
• Comfortable with data structures, distributed systems, virtualization, and containerization.
• Experience with memory‑corruption bugs and bypassing protections like ASLR, stack canaries, and heap guards.
• Proficiency in Linux internals and ability to program in multiple languages.
• Experience with ethical exploitation tools, reverse engineering, IDA Pro, Ghidra, or source‑code analysis.

• Must commute to the UKTL offices in Birmingham at least twice a week.
• Requires DV clearance with no restrictions or the ability to obtain it.

We actively recruit citizens of all backgrounds and adhere to diversity and equality of opportunity. All candidates meeting the required criteria will be considered for interview.
