Cybersecurity Specialist, AI Model Evaluation

The Opportunity: Cybersecurity Specialist, AI Model Evaluation

10x.team is actively seeking a distinguished group of European-based cybersecurity professionals and security leaders to play a pivotal role in supporting leading frontier AI labs. This mission involves training next-generation AI models, focusing on model shaping rather than traditional penetration testing or SOC work. You will contribute to advanced AI systems reasoning more effectively about cybersecurity across critical areas such as threat modeling, incident response, security architecture, risk assessment, compliance frameworks, and the complex strategic landscape of enterprise defense. This role is ideal for those who excel in adversarial thinking, defensive precision, and are passionate about the future of intelligent security systems.

Your Mission: Reinforcement Learning From Human Feedback (RLHF) Datasets

You will contribute to Reinforcement Learning From Human Feedback (RLHF) datasets that strengthen AI reasoning across cybersecurity and information security contexts. Specifically, you will:

• Draft complex scenarios involving threat analysis, vulnerability assessment, incident response workflows, security architecture decisions, and risk management trade-offs.
• Evaluate and refine AI-generated responses for technical accuracy, operational realism, appropriate severity assessment, and alignment with industry frameworks (NIST CSF, ISO 27001, MITRE ATT&CK, CIS Controls).
• Create prompt variants tailored to different contexts (e.g., CISO board briefing, SOC analyst triage, red team planning, cloud security review, third-party risk assessment, post-breach forensics).
• Design examples that intentionally expose weaknesses in security reasoning; missed attack vectors, flawed risk prioritization, incomplete incident containment, over-reliance on compliance as security.
• Ensure outputs reflect European regulatory and operational realities, including NIS2, DORA, GDPR breach notification, ENISA guidance, national CERT coordination, and sector-specific requirements (financial services, critical infrastructure, healthcare).
• Collaborate asynchronously with our research coordination team.

This role demands structured, high-focus intellectual work, distilling your everyday threat-informed, risk-calibrated thinking into crucial training signals for AI.

Who We're Looking For

We are seeking a practicing or recently practiced cybersecurity professional or security leader with hands-on operational and/or strategic experience within a European context. Minimum requirements include:

• 5+ years of professional experience in cybersecurity, information security, or a CISO/security leadership role.
• Based in an EU or UK jurisdiction with working knowledge of the European threat landscape and regulatory environment.
• Strong expertise in at least two domains (e.g., network security, application security, cloud security, identity and access management, incident response, GRC, OT/ICS security, threat intelligence).
• Familiarity with major frameworks and standards — NIST CSF, ISO 27001/27002, MITRE ATT&CK, CIS Controls, OWASP, COBIT.
• Ability to articulate security reasoning clearly across both technical and executive audiences, and identify flawed assumptions or blind spots quickly.

Bonus qualifications include:

• Current or former CISO, Head of Security, or equivalent leadership role.
• Relevant certifications (CISSP, CISM, OSCP, GIAC, CISA, CEH, or equivalent).
• Experience with European regulatory compliance — NIS2 implementation, DORA readiness, GDPR security requirements, eIDAS trust services.
• Background in critical infrastructure protection (energy, finance, healthcare, transport).
• Experience in security architecture for cloud-native or hybrid environments (AWS, Azure, GCP).
• Incident response or digital forensics experience (DFIR).
• Red team, purple team, or adversary simulation background.
• Experience briefing boards, regulators, or supervisory authorities on cyber risk.
• Teaching, mentoring, or thought leadership in cybersecurity.

What truly matters is your deep understanding of attacker mindsets and how defenders operate under pressure, including real-world trade-offs in security posture, business continuity, regulatory obligations, and resource constraints, and your ability to articulate these with precision.

Commitment & Structure

• Fully remote work arrangement.
• Asynchronous work with flexible scheduling, allowing you to balance with other responsibilities.
• Commitment of 5–15 hours per week.
• Estimated duration: 2–4+ months, with possibilities for extension.
• Engaged as an independent contractor.

High-quality contributors may be invited to longer-term AI training initiatives.

Compensation

Competitive hourly rate, aligned with market standards for senior European cybersecurity professionals. Continuation is driven by performance and quality of contributions.

Why This Matters

This is a unique opportunity to shape how AI systems comprehend cybersecurity at scale, influencing their understanding of adversarial mindsets, defensive trade-offs, regulatory complexities, and operational realities. Your expertise will be embedded in every sharper threat analysis and more realistic attack path generated by frontier models. Join us to be on the right side of the equation, applying security intelligence with global impact.
