Freelance | 8-20 hrs/week | Remote (EU/UK)

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. Rather than conducting traditional security architecture projects, you’ll apply your expertise to help AI systems understand and reason about security architecture at scale.

Who You Are

• A senior-level security architect with significant professional experience within the EU or UK
• Experienced in advising on, preparing, and executing security architectures and cybersecurity solutions
• Skilled at evaluating architectural solutions, security documentation, and compliance
• Comfortable working independently and providing structured, critical feedback
• Available for 8-20 hours per week, with prompt availability

Why Join?

• Flexible, fully remote freelance work that fits your current commitments
• Apply your security architecture expertise in a rapidly evolving, high-impact AI environment
• Directly contribute to building advanced AI security systems
• Free access to our in-house AI Academy to further develop your AI skillset
• Clear onboarding, structured tasks, and ongoing opportunities for collaboration

Please note: these AI Lab missions are not traditional job openings with fixed start dates. Project demand is highly dynamic and matching depends on your expertise, availability, and current AI Lab needs. Some experts are matched within days, while others may wait longer for a suitable project.

Join us to help shape the security architecture expertise of the world’s most advanced AI models!

NOTE

At 10x, there are two types of opportunities:

1. Traditional freelance missions

These are regular project-based opportunities where the listed mission is the actual project you may work on.

2. 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.
