You will join a pioneering security research team at the intersection of generative AI and cybersecurity. As an expert human-in-the-loop, you'll validate cloud vulnerability findings from AI models, conduct deep research into infrastructure threats, and create authoritative labels that train models to distinguish critical risks from noise at scale.

Location: Remote, EU/UK

• Pioneer the future of AI-assisted threat detection by defining how large language models understand and prioritize real-world cloud security vulnerabilities.

• Join a high-caliber team of hands-on leaders with a track record of successful exits, IPOs, and leadership roles at major tech firms.

• Direct product influence where your day-to-day research insights shape the development of next-generation security tools used by thousands of organizations.

What you will do:

• Lead high-volume vulnerability labeling operations and validate cloud security findings to create high-quality training data for AI models.

• Conduct comprehensive research into vulnerabilities affecting EC2, Docker, and cloud infrastructure while building proof-of-concept exploits to validate threat scenarios.

• Translate patterns from your research into actionable product improvements by collaborating directly with engineering and machine learning teams.

The ideal candidate:

• Possesses 5+ years of hands-on security experience with a strong background in vulnerability research and cloud-native attack vectors (AWS/Containers).

• Demonstrates strong technical investigation skills with proficiency in Python or Go for automating research tasks and creating validation tools.

• Combines an analytical mindset with a product-focused approach, capable of communicating complex technical findings to both technical and business stakeholders.

We never post fake jobs

This isn't a trick. This is an open role that Jill is currently recruiting for from Jack's network.
Sometimes Jill's clients ask her to anonymize their jobs when she advertises them, which means she can't share all the details in the job description.
We appreciate this can make them look a bit suspect, but there isn't much we can do about it.

Give Jack a spin! You could land this role. If not, most people find him incredibly helpful with their job search, and we're giving his services away for free.
