Senior Vulnerability Researcher

Salary: £41,000 - 81,000 per year

Requirements:

• Proven experience leading or contributing to advanced vulnerability research initiatives across multiple roles or organisations
• Strong expertise across telecom technologies such as 4G/5G, fibre broadband, and OpenRAN
• Deep understanding of hardware and software development lifecycles, and how they introduce security risks
• Practical knowledge of cryptographic systems, including encryption, authentication, and digital signatures
• Solid grasp of data structures, distributed systems, virtualisation, and containerisation
• Expert-level understanding of network protocols and software internals, from low-level assembly to high-level languages
• Experience with embedded systems, OS internals, and hardware debugging techniques
• Strong knowledge of Linux internals, with the ability to quickly adopt new programming languages
• Demonstrated experience identifying and exploiting memory corruption vulnerabilities, including bypassing modern protections (ASLR, stack canaries, etc.)
• Proficiency in reverse engineering, using tools such as IDA Pro, Ghidra, or equivalent
• Skilled in using debugging tools (e.g., GDB) and advanced exploitation techniques
• Experience building custom tools, research platforms, or test environments to support vulnerability discovery
• Ability to commute to our UKTL offices in Birmingham at least twice a week
• Ability to meet the necessary security standards, including DV clearance with no restrictions; SC clearance may be acceptable to start while DV is in progress

Responsibilities:

• Lead advanced vulnerability research across carrier-grade telecom systems
• Drive investigations into complex, real-world technologies and uncover deep, previously unknown security weaknesses
• Shape the vision for vulnerability research within our organisation
• Define priorities, methodologies, and tooling approaches for research efforts
• Provide technical leadership across multiple domains and guide teams through ambiguous and complex problem spaces
• Design and develop advanced research tooling and environments
• Create bespoke fuzzers, software-defined radio solutions, or entirely new frameworks to enable large-scale experimentation and discovery
• Prototype, iterate, and push technical boundaries by leading by example
• Support and develop other researchers through mentoring, knowledge sharing, and work reviews
• Foster a culture of curiosity and technical excellence
• Apply structured research methodologies to understand complex systems, how they behave, where they fail, and how they can be secured
• Connect insights across hardware, software, and networks to solve real-world security challenges
• Operate within a cutting-edge research environment and explore systems at scale
• Design and evolve the infrastructure that underpins advanced telecom security research
