Each of these carries its own security risks, and the team you lead is responsible for identifying and addressing them so that the company can keep adopting AI with confidence.

Other security roles worth a look

A few links on CyberJobs.cc are referral links: when one leads to a hire, a sign-up or a purchase (a lab, a course or a tool marked Partner), the company behind it may pay CyberJobs.cc a fee. You pay nothing extra, and it never changes the salary an employer offers you or which roles the board lists. Roles from partners who pay us a fee rank a little higher in this list.

Run a security team before?

Security teams sometimes ask us directly for someone with a given specialty, clearance or certification. Join the candidate pool once and we put you forward when a brief matches, and only after you say yes. No cost to you.
