How to apply for AI Red Team Engineer

About White Circle

White Circle is a specialized firm focused on securing AI interactions, helping companies test and protect their AI systems. They stand out by combining red teaming expertise with a product-oriented approach, making them a leader in AI safety. Working here means contributing to cutting-edge security in one of the fastest-growing fields.

About the role

As an AI Red Team Engineer, you will conduct adversarial testing on LLM-powered systems to uncover vulnerabilities like jailbreaks and prompt injection. Your work directly impacts customer trust and product security, with a focus on creating repeatable automation and clear documentation. This role is ideal for those passionate about AI security and offensive testing.

A typical day

You might start by reviewing new LLM models or features to identify attack surfaces, then write Python scripts to automate adversarial tests. After running attacks, you'd analyze results, document findings for customer demos, and update the attack library with new prompts and test cases.

Who White Circle is looking for

• Deep understanding of LLM vulnerabilities (e.g., jailbreaks, prompt injection, data leakage) and hands-on experience exploiting them.
• Proficient in Python for scripting automated attacks, scoring responses, and generating test reports.
• Experienced in security testing with a strong ability to document findings clearly for customer demos and security reviews.
• Skilled in building and maintaining attack libraries, including prompts, test cases, rubrics, and regression tests.

Tips for this application

• Highlight specific examples of LLM vulnerabilities you've discovered or tested, such as a successful jailbreak or prompt injection attack.
• Showcase your Python automation skills by providing a link to a GitHub repo with scripts for adversarial testing or scoring.
• Tailor your resume to emphasize experience with security documentation, especially for customer-facing demos or reviews.
• Mention any experience building test libraries or regression test suites, as this is a key responsibility.
• Research White Circle's blog or case studies to understand their testing methodology and reference it in your cover letter.

What to cover in your cover letter

['Emphasize your hands-on experience with LLM adversarial testing and specific techniques (jailbreaks, prompt injection).', 'Highlight your ability to automate testing in Python and produce clear, actionable reports.', 'Show enthusiasm for building and maintaining an attack library, as this is a core part of the role.', "Connect your skills to White Circle's mission of helping companies test and protect AI interactions."]

Research before applying

• Read White Circle's blog posts or case studies on AI red teaming to understand their methodology and terminology.
• Explore their product offerings (e.g., testing, protection, observation) to see how this role fits into their suite.
• Look up any recent talks or publications by White Circle team members on LLM security.
• Check their careers page or LinkedIn for insights into company culture and team structure.

Likely interview topics

Based on the job description, expect questions about:

• Walk me through a time you discovered a novel LLM vulnerability. How did you test and document it?
• How would you design an automated pipeline to test for prompt injection at scale?
• Describe your approach to building a regression test suite for adversarial prompts.
• How do you prioritize which attacks to test when faced with a new LLM system?
• Can you explain how you would present a security finding to a non-technical customer?

Common mistakes to avoid

• Don't submit a generic application; this role requires specific LLM and adversarial testing expertise, so tailor every part.
• Avoid focusing only on theoretical knowledge; they want evidence of hands-on automation and testing.
• Don't overlook the documentation aspect; failing to show you can write clear reports for customers is a common mistake.
