Project Overview:
We are seeking a skilled Cybersecurity AI Trainer to work as a project consultant in our AI Labor Marketplace. This is not a full-time employment position - you will be engaged as an expert project consultant on a contract basis.
Location: U.S.-based experts only
Engagement: Part-time, project-based expert evaluation work
Work Type: Remote
We’re collaborating on a research initiative to improve how AI systems support Microsoft security analysts. The goal is to evaluate and enhance AI-assisted detections across Sentinel, Entra ID and Microsoft 365 by combining expert human judgement with structured evaluation methods. Your insights as a detection engineer or threat hunter will help shape the next generation of AI-driven threat detection and triage tools.
This is a project-based consultant role. Consultants will be paid on a per-project basis; hourly rates are estimates based upon anticipated time of completion. Consultants will control their own schedule, provide their own tools to perform the work, and are free to simultaneously provide services to other vendors and employers to the extent permitted by those vendors and employers.
