Network & Infrastructure Security Analyst (AI Training)

About The Role

We're partnering with the world's leading AI research labs to build the next generation of AI-driven security systems — and we need seasoned security practitioners to make it happen.

If you've spent years in the trenches defending enterprise networks, hunting threats, or managing security infrastructure, this is your opportunity to apply that hard-won expertise to frontier AI development. Your real-world knowledge of how attacks unfold, how controls fail, and how defenders respond is exactly what's needed to make AI security systems smarter and more reliable.
