Successfully executing an LLM red teaming engagement, as outlined in the LLM Red Teaming Lifecycle, requires a blend of specialized skills. While a single individual might handle multiple responsibilities in smaller setups, larger or more complex operations benefit from a well-defined team structure. Each role brings a unique perspective and expertise, contributing to a more thorough and impactful assessment. Understanding these roles is important before you start setting objectives for an engagement.
An effective LLM red team often comprises individuals with diverse backgrounds, ranging from AI/ML expertise to traditional cybersecurity and ethics. Here are some common roles you'll encounter or may need to fill:
The Red Team Lead is the orchestrator of the entire operation. They are responsible for the overall strategy, planning, and execution of the red teaming engagement.
This role requires strong leadership, communication, and project management skills, along with a solid understanding of both red teaming principles and LLM technologies.
This role is at the heart of testing the LLM's direct vulnerabilities. These specialists possess a deep understanding of how LLMs process language and where their weaknesses lie.
This specialist often has a background in natural language processing, AI safety, or creative problem-solving, combined with a knack for thinking like an attacker.
While some LLM red teaming is black-box, a Data Scientist or ML Engineer on the red team can provide deeper insights, especially in grey-box or white-box scenarios, or when assessing vulnerabilities related to the model's training or architecture.
This role requires a strong foundation in machine learning, data analysis, and often programming skills in languages like Python.
LLMs don't exist in a vacuum. They are part of larger systems, with APIs, databases, and network infrastructure. The Security Engineer brings traditional cybersecurity expertise to the team.
This individual is typically skilled in network security, application security testing, and infrastructure hardening.
Given the potential for LLMs to generate harmful content, exhibit biases, or be misused, the Ethics and Safety Advisor plays an essential part in guiding the red team's activities responsibly.
This role often requires expertise in AI ethics, responsible AI development, and sometimes legal or policy backgrounds.
Clear communication of findings is as important as the discovery itself. While other team members contribute to documentation, a dedicated Technical Writer can ensure the final report is actionable and understandable.
Strong writing skills and the ability to understand and articulate complex technical issues are necessary for this role.
While team composition is flexible, a typical structure might involve a lead coordinating various specialists who focus on different aspects of the LLM system.

It's important to remember that these roles are not always rigidly separated. In smaller organizations or on projects with limited resources, one person might wear multiple hats. For instance, an LLM Security Specialist might also handle some data science tasks or contribute heavily to report writing.
The key is that the responsibilities associated with these roles are covered. Effective LLM red teaming hinges on a collaborative environment where team members share insights and work together. An LLM Security Specialist might discover an anomaly that requires a Data Scientist's deeper model knowledge to exploit, or a Security Engineer might find an API vulnerability that gives an LLM Specialist a new attack vector.
The specific composition of your LLM red team will depend on:
As you move through the LLM red teaming lifecycle described earlier, from planning and reconnaissance to exploitation and reporting, individuals in these roles will take the lead on different tasks, but continuous communication and knowledge sharing are essential for success. With a clear understanding of who does what, the team is better prepared to define specific objectives and the scope of the red teaming operation, which we will discuss next.
