Are you an experienced security architect who instinctively spots gaps in security reasoning and understands the complex realities of security architecture? Do you have 8 to 20 hours per week available alongside your main job or consulting projects? Join us in shaping how AI understands and applies security architecture expertise at scale.

About The Role

10x.team connects expert freelancers with leading AI labs building next-generation models. We are looking for knowledgeable security architects based in the EU or UK to enhance the accuracy, depth, and real-world relevance of AI-powered security systems.

What You Will Do

• Review and refine AI-generated outputs related to security architecture, cyber risk assessments, mitigation strategies, and practical aspects of security design
• Evaluate AI responses for accuracy, practicality, and compliance with real-world security requirements
• Draft realistic security architecture scenarios based on your direct professional experience
• Create scenario variations from different perspectives (e.g. security architect, client, IT leader, or regulator)
• Identify gaps, oversights, or weak reasoning in AI-generated security content
  
  

In simple terms: You will assess and improve AI-generated content, ensuring it reflects true security architecture reasoning, authentic security documentation, and practical procedures.

NOTE

At 10x, There Are Two Types Of Opportunities

• Traditional freelance missions These are regular project-based opportunities where the listed mission is the actual project you may work on.
• AI Lab roles For AI Lab roles, we scout, review, and approve profiles for access to future project opportunities.
  
  

The missions listed for AI Lab roles are not traditional job openings. AI Lab work is often highly confidential as this exposes information of what an AI Lab is working on, and project requests are unpredictable. When an AI Lab request comes in, we often need to respond within 24 hours with suitable talent.

Matching depends on the specific needs of each AI Lab project and your niche expertise. Once your profile is reviewed and approved, you may be matched to relevant AI Lab projects when suitable opportunities arise.

This can happen within hours, but it may also take months, depending on the researchers at the AI labs and their project needs.
