This position offers the flexibility to work remotely and on a freelance basis, contributing to cutting-edge AI projects. The role requires a minimum of 2 years of experience in network or infrastructure security.
Key Responsibilities:
- Analyze realistic enterprise network, endpoint, and email security scenarios to evaluate how threats, controls, and failures interact in production environments.
- Review firewall, EDR, and infrastructure security cases — identifying what went wrong, why, and what the business impact is.
- Classify incidents, misconfigurations, and control failures using structured frameworks based on real operational data.
- Create, label, and validate security training and evaluation datasets used to improve AI models.
- Provide clear, expert-level explanations of root causes and remediation paths that AI systems can learn from.
Key Skills:
- 2+ years of hands-on experience in network security, infrastructure security, or endpoint security roles.
- Solid familiarity with firewalls, EDR platforms, email security gateways, IAM systems, and SIEMs.
- Deep understanding of how real enterprises deploy, operate, and fail at security controls.
- Able to clearly articulate security issues, root causes, and business risk — in writing.
- Self-motivated, detail-oriented, and comfortable working independently on task-based assignments.
- Experience with threat hunting, incident response, or red/blue team operations (nice to have).
- Background in security architecture, cloud security, or zero-trust environments (nice to have).
- Familiarity with AI systems, data labeling, or security research workflows (nice to have).
